Rev. 2.00 May. 08, 2008 Page iii of xxiv REJ09B0344-0200 General Precautions on Handling of Product 1. Treatment of NC Pins Note: Do not connect anything to the NC pins. The NC (not connected) pins are either not connected to any of the internal circuitry or are used as test pins or to reduce noise. If something is connected to the NC pins, the operation of the LSI is not guaranteed. 2. Treatment of Unused Input Pins Note: Fix all unused input pins to high or low level. Generally, the input pins of CMOS products are high-impedance input pins. If unused pins are in their open states, intermediate levels are induced by noise in the vicinity, a passthrough current flows internally, and a malfunction may occur. 3. Processing before Initialization Note: When power is first supplied, the product's state is undefined. The states of internal circuits are undefined until full power is supplied throughout the chip and a low level is input on the reset pin. During the period where the states are undefined, the register settings and the output state of each pin are also undefined. Design your system so that it does not malfunction because of processing while it is in this undefined state. For those products which have a reset function, reset the LSI immediately after the power supply has been turned on. 4. Prohibition of Access to Undefined or Reserved Addresses Note: Access to undefined or reserved addresses is prohibited. The undefined or reserved addresses may be used to expand functions, or test registers may have been be allocated to these addresses. Do not access these registers; the system's operation is not guaranteed if they are accessed.

Index Rev. 2.00 May. 08, 2008 Page v of xxiv REJ09B0344-0200 Preface This LSI is an RISC (Reduced Instruction Set Computer) microcomputer which includes a Renesas Technology-original RISC CPU as its core, and the peripheral functions required to configure a system. Target Users: This manual was written for users who will be using this LSI in the design of application systems. Target users are expected to understand the fundamentals of electrical circuits, logical circuits, and microcomputers. Objective: This manual was written to explain the hardware functions and electrical characteristics of this LSI to the target users. Refer to the SH-2A, SH2A-FPU Software Manual for a detailed description of the instruction set. Notes on reading this manual: * In order to understand the overall functions of the chip Read the manual according to the contents. This manual can be roughly categorized into parts on the CPU, system control functions, peripheral functions and electrical characteristics. * In order to understand the details of the CPU's functions Read the SH-2A, SH2A-FPU Software Manual. * In order to understand the details of a register when its name is known Read the index that is the final part of the manual to find the page number of the entry on the register. The addresses, bits, and initial values of the registers are summarized in section 26, List of Registers. Rev. 2.00 May. 08, 2008 Page vi of xxiv REJ09B0344-0200 * Examples The notation used for register names, bit names, numbers, and symbols in this manual is described below. (1) Registers The style (register name)_(channel number) is used in cases where the same or a similar function is implemented on more than one channel. Example: CMCSR_0 (2) Bits When bit names are given in this manual, the higher-order bits are to the left and the lower-order bits are to the right. Example: CKS1, CKS0 (3) Numbers Binary numbers are given as B'xxxx, hexadecimal are given as H'xxxx, and decimal are given as xxxx. Examples: B'11 or 11, H'EFA0, 1234 (4) Symbols An overbar is added to the names of active-low signals. Example: WDTOVF (4) (1) 14.2.2 Compare Match Control/Status Register_0, _1 (CMCSR_0, CMCSR_1) CMCSR indicates compare match generation, enables or disables interrupts, and selects the counter input clock.Generation of a WDTOVF signal or interrupt initializes the TCNT value to 0. 14.3 Operation 14.3.1 Interval Count Operation When an internal clock is selected with the CKS1 and CKS0 bits in CMCSR and the STR bit in CMSTR is set to 1, CMCNT starts incrementing using the selected clock. When the values in CMCNT and the compare match constant register (CMCOR) match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1. When the CKS1 and CKS0 bits are set to B'01 at this time, a f/4 clock is selected. Rev. 0.50, 10/04, page 416 of 914 (2) (3) Note: The bit names and sentences in the above figure are examples, and have nothing to do with the contents of this manual. Rev. 2.00 May. 08, 2008 Page vii of xxiv REJ09B0344-0200 * Notation in bit figures and tables describing arrangements of bits Each register description includes a figure that illustrates the arrangement of bits and a table that describes the meanings of settings in the bits. (1) Bit Indicates the bit number. In the case of a 32-bit register, the bits are arranged in order from 31 to 0, and in the case of a 16-bit register, the bits are arranged in the order from 15 to 0. (2) Bit Name The short form of the name of the bit or bit field within the register. When the individual bits of bit fields have to be clearly indicated, notation allowing this is included (e.g., ASID[3:0]). A reserved bit is indicated by -. Instead of a bit name, a blank is used for some bits, such as those of timer counters. (3) Initial Value Indicates the value of each bit after a power-on reset, i.e., the initial value. 0: Initial value is 0 1: Initial value is 1 -: Initial value is undefined (4) R/W Indicates whether each bit is readable or writable, or either writing to or reading from the bit is prohibited. The notation is as follows: R/W: Bit or field is readable and writable. R/(W): Bit or field is readable and writable. However, writing is only performed to clear the flag. R: Bit or field is readable and writable. However, "R" is indicated for all reserved bits. When writing to the bit is required, write the value stated in the bit table or the initial value. W: Bit or field is readable and writable. However, only the value in the bit table is guaranteed when reading from the bit. (5) Description Describes the function enabled by setting the bit. Bit: 15 - 14 13 ASID 12 11 10 - 9 - 8 - 7 - 6 - 5 - 4 Q 3 2 ACMP[2:0] 1 0 IFE Initial value: 0 R/W: R 0 R/W 0 R/W 0 R/W 0 R/W 0 R 1 R 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W (1) Bit 15 14 to 11 10 9 (2) Bit Name (3) (4) Description (5) Initial Value R/W 0 0000 0 1 0 R R/W R R - ASID Reserved This bit is always read as 0. The write value should always be 0. Address Identifier Enables or disables the pin function. Reserved This bit is always read as 0. Reserved This bit is always read as 1. - - - Note: The bit names and sentences in the above figure are examples, and have nothing to do with the contents of this manual.

The CPU in this LSI has a RISC-type (Reduced Instruction Set Computer) instruction set and uses a superscalar architecture and a Harvard architecture, which greatly improves instruction execution speed. In addition, the 32-bit internal-bus architecture enhances data processing power. With this CPU, it has become possible to assemble low-cost, high-performance, and highfunctioning systems, even for applications that were previously impossible with microprocessors, such as realtime control, which demands high speeds. In addition, this LSI includes on-chip peripheral functions necessary for system configuration, such as a large-capacity ROM, a ROM cache, a RAM, a direct memory access controller (DMAC), multi-function timer pulse units 2 (MTU2 and MTU2S), a serial communication interface with FIFO (SCIF), an A/D converter, a D/A converter, an interrupt controller (INTC), 2 I/O ports, and I C bus interface 3 (IIC3). This LSI also provides an external memory access support function to enable direct connection to various memory devices or peripheral LSIs. These on-chip functions significantly reduce costs of designing and manufacturing application systems. The features of this LSI are listed in table 1.1.

The sixteen 32-bit general registers are numbered R0 to R15. General registers are used for data processing and address calculation. R0 is also used as an index register. Several instructions have R0 fixed as their only usable register. R15 is used as the hardware stack pointer (SP). Saving and restoring the status register (SR) and program counter (PC) in exception handling is accomplished by referencing the stack using R15. 31 R0*1 R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 R13 R14 R15, SP (hardware stack pointer)*2 0 Notes: 1. R0 functions as an index register in the indexed register indirect addressing mode and indexed GBR indirect addressing mode. In some instructions, R0 functions as a fixed source register or destination register. 2. R15 functions as a hardware stack pointer (SP) during exception processing. Figure 2.1 General Registers Rev. 2.00 May. 08, 2008 Page 15 of 1200 REJ09B0344-0200 Section 2 CPU 2.1.2 Control Registers The control registers consist of four 32-bit registers: the status register (SR), the global base register (GBR), the vector base register (VBR), and the jump table base register (TBR). The status register indicates instruction processing states. The global base register functions as a base address for the GBR indirect addressing mode to transfer data to the registers of on-chip peripheral modules. The vector base register functions as the base address of the exception handling vector area (including interrupts). The jump table base register functions as the base address of the function table area. 31 14 13 BO CS 9876543210 MQ I[3:0] ST Status register (SR) 31 GBR 0 Global base register (GBR) 0 VBR 31 Vector base register (VBR) 0 31 TBR Jump table base register (TBR) Figure 2.2 Control Registers (1) Status Register (SR) Bit: 31 - 30 - 29 - 28 - 27 - 26 - 25 - 24 - 23 - 22 - 21 - 20 - 19 - 18 - 17 - 16 - Initial value: R/W: Bit: 0 R 15 - 0 R 14 BO 0 R 13 CS 0 R 12 - 0 R 11 - 0 R 10 - 0 R 9 M 0 R 8 Q 0 R 7 0 R 6 I[3:0] 0 R 5 0 R 4 0 R 3 - 0 R 2 - 0 R 1 S 0 R 0 T Initial value: R/W: 0 R 0 R/W 0 R/W 0 R 0 R 0 R R/W R/W 1 R/W 1 R/W 1 R/W 1 R/W 0 R 0 R R/W R/W Rev. 2.00 May. 08, 2008 Page 16 of 1200 REJ09B0344-0200 Section 2 CPU Bit Bit Name Initial Value All 0 R/W R Description Reserved These bits are always read as 0.

Rev. 2.00 May. 08, 2008 Page 17 of 1200 REJ09B0344-0200 Section 2 CPU 2.1.3 System Registers The system registers consist of four 32-bit registers: the high and low multiply and accumulate registers (MACH and MACL), the procedure register (PR), and the program counter (PC). MACH and MACL store the results of multiply or multiply and accumulate operations. PR stores the return address from a subroutine procedure. PC indicates the program address being executed and controls the flow of the processing. 31 MACH MACL 31 PR 0 0 Multiply and accumulate register high (MACH) and multiply and accumulate register low (MACL): Store the results of multiply or multiply and accumulate operations. Procedure register (PR): Stores the return address from a subroutine procedure. 31 PC 0 Program counter (PC): Indicates the four bytes ahead of the current instruction. Figure 2.3 System Registers (1) Multiply and Accumulate Register High (MACH) and Multiply and Accumulate Register Low (MACL) MACH and MACL are used as the addition value in a MAC instruction, and store the result of a MAC or MUL instruction. (2) Procedure Register (PR) PR stores the return address of a subroutine call using a BSR, BSRF, or JSR instruction, and is referenced by a subroutine return instruction (RTS). (3) Program Counter (PC) PC indicates the address of the instruction being executed. Rev. 2.00 May. 08, 2008 Page 18 of 1200 REJ09B0344-0200 Section 2 CPU 2.1.4 Register Banks For the nineteen 32-bit registers comprising general registers R0 to R14, control register GBR, and system registers MACH, MACL, and PR, high-speed register saving and restoration can be carried out using a register bank. The register contents are automatically saved in the bank after the CPU accepts an interrupt that uses a register bank. Restoration from the bank is executed by issuing a RESBANK instruction in an interrupt processing routine. For details, refer to the SH-2A, SH2A-FPU Software Manual. 2.1.5 Initial Values of Registers Table 2.1 lists the values of the registers after a reset.

If the size of memory operand is a byte (8 bits) or a word (16 bits), it is changed into a longword by expanding the sign-part when loaded into a register. 31 Longword 0 Figure 2.4 Data Format in Registers 2.2.2 Data Formats in Memory Memory data formats are classified into bytes, words, and longwords. Memory can be accessed in 8-bit bytes, 16-bit words, or 32-bit longwords. A memory operand of fewer than 32 bits is stored in a register in sign-extended or zero-extended form. A word operand should be accessed at a word boundary (an even address of multiple of two bytes: address 2n), and a longword operand at a longword boundary (an even address of multiple of four bytes: address 4n). Otherwise, an address error will occur. A byte operand can be accessed at any address. Only big-endian byte order can be selected for the data format. Data formats in memory are shown in figure 2.5. Address m + 1 Address m 31 Byte Address 2n Address 4n Word Longword 23 Byte Address m + 3 Address m + 2 15 Byte Word 7 Byte 0 Figure 2.5 Data Formats in Memory Rev. 2.00 May. 08, 2008 Page 20 of 1200 REJ09B0344-0200 Section 2 CPU 2.2.3 Immediate Data Format Byte (8-bit) immediate data is located in an instruction code. Immediate data accessed by the MOV, ADD, and CMP/EQ instructions is sign-extended and handled in registers as longword data. Immediate data accessed by the TST, AND, OR, and XOR instructions is zero-extended and handled as longword data. Consequently, AND instructions with immediate data always clear the upper 24 bits of the destination register. 20-bit immediate data is located in the code of a MOVI20 or MOVI20S 32-bit transfer instruction. The MOVI20 instruction stores immediate data in the destination register in sign-extended form. The MOVI20S instruction shifts immediate data by eight bits in the upper direction, and stores it in the destination register in sign-extended form. Word or longword immediate data is not located in the instruction code, but rather is stored in a memory table. The memory table is accessed by an immediate data transfer instruction (MOV) using the PC relative addressing mode with displacement. See examples given in section 2.3.1 (10), Immediate Data. Rev. 2.00 May. 08, 2008 Page 21 of 1200 REJ09B0344-0200 Section 2 CPU 2.3 2.3.1 Instruction Features RISC-Type Instruction Set Instructions are RISC type. This section details their functions. (1) 16-Bit Fixed-Length Instructions Basic instructions have a fixed length of 16 bits, improving program code efficiency. (2) 32-Bit Fixed-Length Instructions The SH-2A additionally features 32-bit fixed-length instructions, improving performance and ease of use. (3) One Instruction per State Each basic instruction can be executed in one cycle using the pipeline system. (4) Data Length Longword is the standard data length for all operations. Memory can be accessed in bytes, words, or longwords. Byte or word data in memory is sign-extended and handled as longword data. Immediate data is sign-extended for arithmetic operations or zero-extended for logic operations. It is also handled as longword data. Table 2.2 SH2-A CPU MOV.W ADD Sign Extension of Word Data Description @(disp,PC),R1 Data is sign-extended to 32 bits, and R1 becomes H'00001234. It is R1,R0 next operated upon by an ADD ......... instruction. H'1234 Example of Other CPU ADD.W #H'1234,R0 .DATA.W Note: @(disp, PC) accesses the immediate data. (5) Load-Store Architecture Basic operations are executed between registers. For operations that involve memory access, data is loaded to the registers and executed (load-store architecture). Instructions such as AND that manipulate bits, however, are executed directly in memory. Rev. 2.00 May. 08, 2008 Page 22 of 1200 REJ09B0344-0200 Section 2 CPU (6) Delayed Branch Instructions With the exception of some instructions, unconditional branch instructions, etc., are executed as delayed branch instructions. With a delayed branch instruction, the branch is taken after execution of the instruction immediately following the delayed branch instruction. This reduces disturbance of the pipeline control when a branch is taken. In a delayed branch, the actual branch operation occurs after execution of the slot instruction. However, instruction execution such as register updating excluding the actual branch operation, is performed in the order of delayed branch instruction delay slot instruction. For example, even though the contents of the register holding the branch destination address are changed in the delay slot, the branch destination address remains as the register contents prior to the change. Table 2.3 SH-2A CPU BRA ADD TRGET R1,R0 Delayed Branch Instructions Description Executes the ADD before branching to TRGET. Example of Other CPU ADD.W BRA R1,R0 TRGET (7) Unconditional Branch Instructions with No Delay Slot The SH-2A additionally features unconditional branch instructions in which a delay slot instruction is not executed. This eliminates unnecessary NOP instructions, and so reduces the code size. (8) Multiply/Multiply-and-Accumulate Operations 16-bit x 16-bit 32-bit multiply operations are executed in one to two cycles. 16-bit x 16-bit + 64-bit 64-bit multiply-and-accumulate operations are executed in two to three cycles. 32-bit x 32-bit 64-bit multiply and 32-bit x 32-bit + 64-bit 64-bit multiply-and-accumulate operations are executed in two to four cycles. (9) T Bit The T bit in the status register (SR) changes according to the result of the comparison. Whether a conditional branch is taken or not taken depends upon the T bit condition (true/false). The number of instructions that change the T bit is kept to a minimum to improve the processing speed. Rev. 2.00 May. 08, 2008 Page 23 of 1200 REJ09B0344-0200 Section 2 CPU Table 2.4 SH-2A CPU CMP/GE BT BF ADD CMP/EQ BT T Bit Description R1,R0 TRGET0 TRGET1 #-1,R0 #0,R0 TRGET T bit is set when R0 R1.

Example of Other CPU CMP.W BGE BLT SUB.W BEQ R1,R0 TRGET0 TRGET1 #1,R0 TRGET (10) Immediate Data Byte immediate data is located in an instruction code. Word or longword immediate data is not located in instruction codes but in a memory table. The memory table is accessed by an immediate data transfer instruction (MOV) using the PC relative addressing mode with displacement. With the SH-2A, 17- to 28-bit immediate data can be located in an instruction code. However, for 21- to 28-bit immediate data, an OR instruction must be executed after the data is transferred to a register.

That value is transferred to the register by loading the immediate data during the execution of the instruction, and the data is accessed in register indirect addressing mode. With the SH-2A, when data is referenced using an absolute address not exceeding 28 bits, it is also possible to transfer immediate data located in the instruction code to a register and to reference the data in register indirect addressing mode. However, when referencing data using an absolute address of 21 to 28 bits, an OR instruction must be used after the data is transferred to a register.

Instruction execution cycles: The execution cycles shown in the table are minimums. In practice, the number of instruction execution states will be increased in cases such as the following: a. When there is a conflict between an instruction fetch and a data access b. When the destination register of a load instruction (memory register) is the same as the register used by the next instruction. 2. Depending on the operand size, displacement is scaled by x1, x2, or x4. For details, refer to the SH-2A, SH2A-FPU Software Manual.

Figure 2.6 shows the transitions between the states. Power-on reset from any state Manual reset from any state Power-on reset state Manual reset state Reset canceled Reset state Interrupt source or DMA address error occurs Bus request cleared Exception handling state Bus request generated Exception handling source occurs Exception handling ends NMI interrupt or IRQ interrupt occurs Bus-released state Bus request generated Bus request generated Bus request cleared Bus request cleared Program execution state STBY bit set for SLEEP instruction STBY bit cleared for SLEEP instruction Sleep mode Software standby mode Power-down state Figure 2.6 Transitions between Processing States Rev. 2.00 May. 08, 2008 Page 53 of 1200 REJ09B0344-0200 Section 2 CPU (1) Reset State In the reset state, the CPU is reset. There are two kinds of reset, power-on reset and manual reset. (2) Exception Handling State The exception handling state is a transient state that occurs when exception handling sources such as resets or interrupts alter the CPU's processing state flow. For a reset, the initial values of the program counter (PC) (execution start address) and stack pointer (SP) are fetched from the exception handling vector table and stored; the CPU then branches to the execution start address and execution of the program begins. For an interrupt, the stack pointer (SP) is accessed and the program counter (PC) and status register (SR) are saved to the stack area. The exception service routine start address is fetched from the exception handling vector table; the CPU then branches to that address and the program starts executing, thereby entering the program execution state. (3) Program Execution State In the program execution state, the CPU sequentially executes the program. (4) Power-Down State In the power-down state, the CPU stops operating to reduce power consumption. The SLEEP instruction places the CPU in the sleep mode or the software standby mode. (5) Bus-Released State In the bus-released state, the CPU releases bus to a device that has requested it.

The operating mode is determined by the setting of FWE, MD1, and MD0 pins. Table 3.1 shows the allowable combinations of these pin settings; do not set these pins in the other way than the shown combinations. When power is applied to the system, be sure to conduct power-on reset. The MCU operating mode can be selected from MCU extension modes 0 to 2 and single chip mode.

The CPG consists of a crystal oscillator, PLL circuits, and divider circuits. 4.1 Features * Clock operating modes Either the internal crystal resonator or the input on the external clock-signal line can be selected. * Five clocks generated independently An internal clock (I) for the CPU, a peripheral clock (P) for the peripheral modules, a bus clock (B = CK) for the external bus interface, an MTU2S clock (M) for the MTU2S module, and an AD clock (A) for the ADC module can be generated independently. * Frequency change function Internal and peripheral clock frequencies can be changed independently using the PLL (phase locked loop) circuits and divider circuits within the CPG. Frequencies are changed by software using frequency control register (FRQCR) settings. * Power-down mode control The clock can be stopped for sleep mode and software standby mode, and specific modules can be stopped using the module standby function. For details on clock control in the power-down modes, see section 23, Power-Down Modes. Figure 4.1 shows a block diagram of the clock pulse generator.

The multiplication rate is set by the frequency control register. When this is done, the phase of the rising edge of the internal clock (I) is controlled so that it will agree with the phase of the rising edge of the CK pin. (2) PLL Circuit 2 PLL circuit 2 multiplies the input clock frequency from the crystal oscillator or EXTAL pin by 4. The multiplication rate is fixed according to the clock operating mode. The clock operating mode is specified by the MD_CLK0 and MD_CLK2 pins. For details on the clock operating mode, see table 4.2. (3) Crystal Oscillator The crystal oscillator is an oscillation circuit in which a crystal resonator is connected to the XTAL pin or EXTAL pin. This can be used according to the clock operating mode. (4) Divider 1 Divider 1 generates a clock signal at the operating frequency used by the internal clock (I), the bus clock (B), the peripheral clock (P), the MTU2S clock (M), or the AD clock (A). The operating frequency can be 1, 1/2, 1/4, or 1/8 times the output frequency of PLL circuit 1. However, set the internal clock (I) so that its frequency is not less than the clock frequency of the CK pin, and set the peripheral clock (P) so that its frequency is not more than the clock frequency of the CK pin. The division ratio is set in the frequency control register (FRQCR). (5) Clock Frequency Control Circuit The clock frequency control circuit controls the clock frequency using the MD_CLK0 and MD_CLK2 pins and the frequency control register (FRQCR). Rev. 2.00 May. 08, 2008 Page 63 of 1200 REJ09B0344-0200 Section 4 Clock Pulse Generator (CPG) (6) Standby Control Circuit The standby control circuit controls the states of the clock pulse generator and other modules during clock switching, or sleep or software standby mode. (7) Frequency Control Register (FRQCR) The frequency control register (FRQCR) has control bits assigned for the following functions: clock output/non-output from the CK pin during software standby mode, the frequency multiplication ratio of PLL circuit 1, and the frequency division ratio of the internal clock (I) and the peripheral clock (P). (8) MTU2S Clock Frequency Control Register (MCLKCR) The MTU2S clock frequency control register (MCLKCR) has control bits assigned for the following functions: MTU2S clock (M) output/non-output and the frequency division ratio. (9) AD Clock Frequency Control Register (ACLKCR) The AD clock frequency control register (ACLKCR) has control bits assigned for the following functions: AD clock (A) output/non-output and the frequency division ratio. (10) Standby Control Register The standby control register has bits for controlling the power-down modes. See section 23, Power-Down Modes, for more information.

Table 4.3 shows the usable frequency ranges in the clock operating modes.

This allows a crystal with a lower frequency to be used. Either a crystal resonator with a frequency in the range from 8 to 10 MHz or an external signal in the same frequency range input on the EXTAL pin can be used. When the CK output is in use, the frequency range is from 32 to 40 MHz. When an input signal on the EXTAL pin is in use, the XTAL pin should be left open.

All of these are controlled by software through the frequency control register (FRQCR). The methods are described below. 4.5.1 Changing the Multiplication Rate A PLL settling time is required when the multiplication rate of PLL circuit 1 is changed. When the multiplication rate is changed, the LSI temporarily stops automatically and the internal watchdog timer (WDT) starts counting the settling time. When the count of the WDT overflows, the LSI restarts operating with the set clock frequency. The following shows this setting procedure. 1. In the initial state, the multiplication rate of PLL circuit 1 is 1 time. 2. Set a value that will become the specified oscillation settling time in the WDT and stop the WDT. The following must be set: WTCSR.TME = 0: WDT stops WTCSR.CKS[2:0]: Division ratio of WDT count clock WTCNT counter: Initial counter value For setting of the counter, determine the overflow period with the frequency after the peripheral clock (P) setting change. 3. Set the desired value in the STC[1:0] bits. The division ratio can also be set in the IFC[2:0] and PFC[2:0] bits. 4. This LSI pauses temporarily and the WDT starts incrementing. The internal and peripheral clocks both stop and the WDT is supplied with the clock. The clock will continue to be output at the CK pin. This state is the same as software standby mode. Whether or not registers are initialized depends on the module. For details, see table 23.4 in section 23, Power-Down Modes. 5. Supply of the clock that has been set begins at WDT count overflow, and this LSI begins operating again. The WDT stops counting after it overflows. Rev. 2.00 May. 08, 2008 Page 73 of 1200 REJ09B0344-0200 Section 4 Clock Pulse Generator (CPG) 4.5.2 Changing the Division Ratio Counting by the WDT does not proceed if the frequency divisor is changed but the multiplier is not. 1. In the initial state, IFC[2:0] = B'000 and PFC[2:0] = B'011. 2. Set the desired value in the IFC[2:0] and PFC[2:0] bits. The values that can be set are limited by the clock operating mode and the multiplication rate of PLL circuit 1. Note that if the wrong value is set, this LSI will malfunction. 3. After the register bits (IFC[2:0] and PFC[2:0]) have been set, the clock is supplied of the new division ratio. Note: When executing the SLEEP instruction after the frequency has been changed, be sure to read the frequency control register (FRQCR) three times before executing the SLEEP instruction.

The bypass capacitor must be inserted as close to the power supply pins of the LSI as possible. Note that the capacitance and frequency characteristics of the bypass capacitor must be appropriate for the operating frequency of the LSI. 4.6.3 Note on Using a PLL Oscillation Circuit In the PLLVcc and PLLVss connection pattern for the PLL, signal lines from the board power supply pins must be as short as possible and pattern width must be as wide as possible to reduce inductive interference. Since the analog power supply pins of the PLL are sensitive to the noise, the system may malfunction due to inductive interference at the other power supply pins. To prevent such malfunction, the analog power supply pin Vcc and digital power supply pin VccQ should not supply the same resources on the board if at all possible.

Table 5.2 Exception Reset Timing of Exception Source Detection and Start of Exception Handling Source Power-on reset Timing of Source Detection and Start of Handling Starts when the RES pin changes from low to high, when the H-UDI reset negate command is set after the H-UDI reset assert command has been set, or when the WDT overflows.

Detected when instruction is decoded and starts when the previous executing instruction finishes executing. Starts upon attempted execution of a RESBANK instruction when saving has not been performed to register banks. In the state where saving has been performed to all register bank areas, starts when acceptance of register bank overflow exception has been set by the interrupt controller (the BOVE bit in IBNR of the INTC is 1) and an interrupt that uses a register bank has occurred and been accepted by the CPU. Starts from the execution of a TRAPA instruction. Starts from the decoding of undefined code anytime except immediately after a delayed branch instruction (delay slot). Starts from the decoding of undefined code placed immediately after a delayed branch instruction (delay slot), of instructions that rewrite the PC, of 32-bit instructions, of the RESBANK instruction, of the DIVS instruction, or of the DIVU instruction.

See section 5.1.3, Exception Handling Vector Table, for more information. The vector base register (VBR) is then initialized to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized. The BN bit in IBNR of the interrupt controller (INTC) is also initialized to 0. The program begins running from the PC address fetched from the exception handling vector table. (2) Exception Handling Triggered by Address Errors, Register Bank Errors, Interrupts, and Instructions SR and PC are saved to the stack indicated by R15. In the case of interrupt exception handling other than NMI or UBC with usage of the register banks enabled, general registers R0 to R14, control register GBR, system registers MACH, MACL, and PR, and the vector number of the interrupt exception handling to be executed are saved to the register banks. In the case of exception handling due to an address error, register bank error, NMI interrupt, UBC interrupt, or instruction, saving to a register bank is not performed. When saving is performed to all register banks, automatic saving to the stack is performed instead of register bank saving. In this case, an interrupt controller setting must have been made so that register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the INTC is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the INTC is 1), register bank overflow exception will be generated. In the case of interrupt exception handling, the interrupt priority level is written to the I3 to I0 bits in SR. In the case of exception handling due to an address error or instruction, the I3 to I0 bits are not affected. The start address is then fetched from the exception handling vector table and the program begins running from that address. Rev. 2.00 May. 08, 2008 Page 80 of 1200 REJ09B0344-0200 Section 5 Exception Handling 5.1.3 Exception Handling Vector Table Before exception handling begins running, the exception handling vector table must be set in memory. The exception handling vector table stores the start addresses of exception service routines. (The reset exception handling table holds the initial values of PC and SP.) All exception sources are given different vector numbers and vector table address offsets, from which the vector table addresses are calculated. During exception handling, the start addresses of the exception service routines are fetched from the exception handling vector table, which is indicated by this vector table address. Table 5.3 shows the vector numbers and vector table address offsets. Table 5.4 shows how vector table addresses are calculated.

There are two kinds of reset, power-on and manual. As shown in table 5.5, the CPU state is initialized in both a power-on reset and a manual reset.

To reliably reset this LSI, the RES pin should be kept at the low level for the duration of the oscillation settling time at power-on or when in software standby mode (when the clock is halted), or at least 20-tcyc when the clock is running. In the power-on reset state, the internal state of the CPU and all the on-chip peripheral module registers are initialized. See appendix A, Pin States, for the status of individual pins during the power-on reset state. In the power-on reset state, power-on reset exception handling starts when the RES pin is first driven low for a fixed period and then returned to high. The CPU operates as follows: 1. The initial value (execution start address) of the program counter (PC) is fetched from the exception handling vector table. 2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table. 3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized. The BN bit in IBNR of the INTC is also initialized to 0. 4. The values fetched from the exception handling vector table are set in the PC and SP, and the program begins executing. Be certain to always perform power-on reset processing when turning the system power on. (2) Power-On Reset by Means of H-UDI Reset Assert Command When the H-UDI reset assert command is set, this LSI enters the power-on reset state. Power-on reset by means of an H-UDI reset assert command is equivalent to power-on reset by means of the RES pin. Setting the H-UDI reset negate command cancels the power-on reset state. The time required between an H-UDI reset assert command and H-UDI reset negate command is the same as the time to keep the RES pin low to initiate a power-on reset. In the power-on reset state generated by an H-UDI reset assert command, setting the H-UDI reset negate command starts power-on reset exception handling. The CPU operates in the same way as when a power-on reset was caused by the RES pin.

In this case, WRCSR of the WDT and FRQCR of the CPG are not initialized by the reset signal generated by the WDT. If a reset caused by the RES pin or the H-UDI reset assert command occurs simultaneously with a reset caused by WDT overflow, the reset caused by the RES pin or the H-UDI reset assert command has priority, and the WOVF bit in WRCSR is cleared to 0. When power-on reset exception processing is started by the WDT, the CPU operates in the same way as when a poweron reset was caused by the RES pin.

To reset this LSI without fail, the MRES pin should be kept at the low level for at least 20-tcyc. In the manual reset state, the CPU's internal state is initialized, but all the on-chip peripheral module registers are not initialized. In the manual reset state, manual reset exception handling starts when the MRES pin is first driven low for a fixed period and then returned to high. The CPU operates as follows: 1. The initial value (execution start address) of the program counter (PC) is fetched from the exception handling vector table. 2. The initial value of the stack pointer (SP) is fetched from the exception handling vector table. 3. The vector base register (VBR) is cleared to H'00000000, the interrupt mask level bits (I3 to I0) of the status register (SR) are initialized to H'F (B'1111), and the BO and CS bits are initialized. The BN bit in IBNR of the INTC is also initialized to 0. 4. The values fetched from the exception handling vector table are set in the PC and SP, and the program begins executing. (2) Manual Reset Initiated by WDT When a setting is made for a manual reset to be generated in the WDT's watchdog timer mode, and WTCNT of the WDT overflows, this LSI enters the manual reset state. When manual reset exception processing is started by the WDT, the CPU operates in the same way as when a manual reset was caused by the MRES pin. When a manual reset is generated, the bus cycle is retained, but if a manual reset occurs while the bus is released or during DMAC burst transfer, manual reset exception handling will be deferred until the CPU acquires the bus. However, if the interval from generation of the manual reset until the end of the bus cycle is equal to or longer than the fixed internal manual reset interval cycles, the internal manual reset source is ignored instead of being deferred, and manual reset exception handling is not executed.

When the executing instruction then finishes, address error exception handling starts. The CPU operates as follows: 1. The exception service routine start address which corresponds to the address error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction. 4. After jumping to the address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. Note: * This is the case in which an address error was caused by data read or write. When an address error is caused by an instruction fetch, and if the bus cycle in which the address error occurred does not end by step 3 above, the CPU restarts the address error exception handling until the bus cycle ends.

(2) Bank Underflow Bank underflow occurs when an attempt is made to execute a RESBANK instruction while saving has not been performed to register banks. 5.4.2 Register Bank Error Exception Handling When a register bank error occurs, register bank error exception handling starts. The CPU operates as follows: 1. The exception service routine start address which corresponds to the register bank error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction for a bank overflow, and the start address of the executed RESBANK instruction for a bank underflow. To prevent multiple interrupts from occurring at a bank overflow, the interrupt priority level that caused the bank overflow is written to the interrupt mask level bits (I3 to I0) of the status register (SR). 4. After jumping to the address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch.

Rev. 2.00 May. 08, 2008 Page 90 of 1200 REJ09B0344-0200 Section 5 Exception Handling 5.5.2 Interrupt Priority Level The interrupt priority order is predetermined. When multiple interrupts occur simultaneously (overlap), the interrupt controller (INTC) determines their relative priorities and starts processing according to the results. The priority order of interrupts is expressed as priority levels 0 to 16, with priority 0 the lowest and priority 16 the highest. The NMI interrupt has priority 16 and cannot be masked, so it is always accepted. The user break interrupt and H-UDI interrupt priority level is 15. Priority levels of IRQ interrupts, and on-chip peripheral module interrupts can be set freely using the interrupt priority registers 01, 02, and 05 to 15 (IPR01, IPR02, and IPR05 to IPR15) of the INTC as shown in table 5.8. The priority levels that can be set are 0 to 15. Level 16 cannot be set. See section 6.3.1, Interrupt Priority Registers 01, 02, 05 to 15 (IPR01, IPR02, IPR05 to IPR15), for details of IPR01, IPR02, and IPR05 to IPR15.

Rev. 2.00 May. 08, 2008 Page 91 of 1200 REJ09B0344-0200 Section 5 Exception Handling 5.5.3 Interrupt Exception Handling When an interrupt occurs, its priority level is ascertained by the interrupt controller (INTC). NMI is always accepted, but other interrupts are only accepted if they have a priority level higher than the priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR). When an interrupt is accepted, interrupt exception handling begins. In interrupt exception handling, the CPU fetches the exception service routine start address which corresponds to the accepted interrupt from the exception handling vector table, and saves SR and the program counter (PC) to the stack. In the case of interrupt exception handling other than NMI or UBC with usage of the register banks enabled, general registers R0 to R14, control register GBR, system registers MACH, MACL, and PR, and the vector number of the interrupt exception handling to be executed are saved in the register banks. In the case of exception handling due to an address error, NMI interrupt, UBC interrupt, or instruction, saving is not performed to the register banks. If saving has been performed to all register banks (0 to 14), automatic saving to the stack is performed instead of register bank saving. In this case, an interrupt controller setting must have been made so that register bank overflow exceptions are not accepted (the BOVE bit in IBNR of the INTC is 0). If a setting to accept register bank overflow exceptions has been made (the BOVE bit in IBNR of the INTC is 1), register bank overflow exception occurs. Next, the priority level value of the accepted interrupt is written to the I3 to I0 bits in SR. For NMI, however, the priority level is 16, but the value set in the I3 to I0 bits is H'F (level 15). Then, after jumping to the start address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. See section 6.6, Operation, for further details of interrupt exception handling.

The CPU operates as follows: 1. The exception service routine start address which corresponds to the vector number specified in the TRAPA instruction is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the TRAPA instruction. 4. After jumping to the address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch. 5.6.3 Slot Illegal Instructions An instruction placed immediately after a delayed branch instruction is said to be placed in a delay slot. When the instruction placed in the delay slot is undefined code, an instruction that rewrites the PC, a 32-bit instruction, an RESBANK instruction, a DIVS instruction, or a DIVU instruction, slot illegal exception handling starts when such kind of instruction is decoded. The CPU operates as follows: 1. The exception service routine start address is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the jump address of the delayed branch instruction immediately before the undefined code, the instruction that rewrites the PC, the 32-bit instruction, the RESBANK instruction, the DIVS instruction, or the DIVU instruction. 4. After jumping to the address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch.

The CPU handles general illegal instructions in the same way as slot illegal instructions. Unlike processing of slot illegal instructions, however, the program counter value stored is the start address of the undefined code. 5.6.5 Integer Division Instructions When an integer division instruction performs division by zero or the result of integer division overflows, integer division instruction exception handling starts. The instructions that may become the source of division-by-zero exception are DIVU and DIVS. The only source instruction of overflow exception is DIVS, and overflow exception occurs only when the negative maximum value is divided by -1. The CPU operates as follows: 1. The exception service routine start address which corresponds to the integer division instruction exception that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the integer division instruction at which the exception occurred. 4. After jumping to the address fetched from the exception handling vector table, program execution starts. The jump that occurs is not a delayed branch.

If it is not, an address error will occur when the stack is accessed during exception handling. 5.9.2 Value of Vector Base Register (VBR) The value of the vector base register must always be a multiple of four. If it is not, an address error will occur when the stack is accessed during exception handling. 5.9.3 Address Errors Caused by Stacking of Address Error Exception Handling When the stack pointer is not a multiple of four, an address error will occur during stacking of the exception handling (interrupts, etc.) and address error exception handling will start up as soon as the first exception handling is ended. Address errors will then also occur in the stacking for this address error exception handling. To ensure that address error exception handling does not go into an endless loop, no address errors are accepted at that point. This allows program control to be shifted to the address error exception service routine and enables error processing. When an address error occurs during exception handling stacking, the stacking bus cycle (write) is executed. During stacking of the status register (SR) and program counter (PC), the SP is decremented by 4 for both, so the value of SP will not be a multiple of four after the stacking either. The address value output during stacking is the SP value, so the address where the error occurred is itself output. This means the write data stacked will be undefined.

The INTC registers set the order of priority of each interrupt, allowing the user to process interrupt requests according to the user-set priority. 6.1 Features * 16 levels of interrupt priority can be set By setting the thirteen interrupt priority registers, the priorities of IRQ interrupts and on-chip peripheral module interrupts can be selected from 16 levels for request sources. * NMI noise canceler function An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt exception service routine, the pin state can be checked, enabling it to be used as the noise canceler function. * Occurrence of interrupt can be reported externally (IRQOUT pin) For example, when this LSI has released the bus mastership, this LSI can inform the external bus master of occurrence of an on-chip peripheral module interrupt and request for the bus mastership. * Register banks This LSI has register banks that enable register saving and restoration required in the interrupt processing to be performed at high speed.

After BN is decremented by 1 due to execution of a RESBANK (restore from register bank) instruction, restoration from the register bank is performed. Rev. 2.00 May. 08, 2008 Page 113 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.4 Interrupt Sources There are five types of interrupt sources: NMI, user break, H-UDI, IRQ, and on-chip peripheral modules. Each interrupt has a priority level (0 to 16), with 0 the lowest and 16 the highest. When set to level 0, that interrupt is masked at all times. 6.4.1 NMI Interrupt The NMI interrupt has a priority level of 16 and is accepted at all times. NMI interrupt requests are edge-detected, and the NMI edge select bit (NMIE) in interrupt control register 0 (ICR0) selects whether the rising edge or falling edge is detected. Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets the interrupt mask level bits (I3 to I0) in the status register (SR) to level 15. 6.4.2 User Break Interrupt A user break interrupt which occurs when a break condition set in the user break controller (UBC) matches has a priority level of 15. The user break interrupt exception handling sets the I3 to I0 bits in SR to level 15. For user break interrupts, see section 7, User Break Controller (UBC). 6.4.3 H-UDI Interrupt The user debugging interface (H-UDI) interrupt has a priority level of 15, and occurs at serial input of an H-UDI interrupt instruction. H-UDI interrupt requests are edge-detected and retained until they are accepted. The H-UDI interrupt exception handling sets the I3 to I0 bits in SR to level 15. For H-UDI interrupts, see section 24, User Debugging Interface (H-UDI). Rev. 2.00 May. 08, 2008 Page 114 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.4.4 IRQ Interrupts IRQ interrupts are input from pins IRQ7 to IRQ0. For the IRQ interrupts, low-level, falling-edge, rising-edge, or both-edge detection can be selected individually for each pin by the IRQ sense select bits (IRQ71S to IRQ01S and IRQ70S to IRQ00S) in interrupt control register 1 (ICR1). The priority level can be set individually in a range from 0 to 15 for each pin by interrupt priority registers 01 and 02 (IPR01 and IPR02). When using low-level sensing for IRQ interrupts, an interrupt request signal is sent to the INTC while the IRQ7 to IRQ0 pins are low. An interrupt request signal is stopped being sent to the INTC when the IRQ7 to IRQ0 pins are driven high. The status of the interrupt requests can be checked by reading the IRQ interrupt request bits (IRQ7F to IRQ0F) in the IRQ interrupt request register (IRQRR). When using edge-sensing for IRQ interrupts, an interrupt request is detected due to change of the IRQ7 to IRQ0 pin states, and an interrupt request signal is sent to the INTC. The result of IRQ interrupt request detection is retained until that interrupt request is accepted. Whether IRQ interrupt requests have been detected or not can be checked by reading the IRQ7F to IRQ0F bits in IRQRR. Writing 0 to these bits after reading them as 1 clears the result of IRQ interrupt request detection. The IRQ interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the accepted IRQ interrupt. Rev. 2.00 May. 08, 2008 Page 115 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.4.5 On-Chip Peripheral Module Interrupts On-chip peripheral module interrupts are generated by the following on-chip peripheral modules: * A/D converter (ADC) * Direct memory access controller (DMAC) * Compare match timer (CMT) * Bus state controller (BSC) * Watchdog timer (WDT) * Multi-function timer pulse unit 2 (MTU2) * Multi-function timer pulse unit 2S (MTU2S) * Port output enable 2 (POE2) * I C bus interface 3 (IIC3) 2 * Serial communication interface with FIFO (SCIF) * WAVE interface (WAVEIF) As every source is assigned a different interrupt vector, the source does not need to be identified in the exception service routine. A priority level in a range from 0 to 15 can be set for each module by interrupt priority registers 05 to 15 (IPR05 to IPR15). The on-chip peripheral module interrupt exception handling sets the I3 to I0 bits in SR to the priority level of the accepted on-chip peripheral module interrupt. Rev. 2.00 May. 08, 2008 Page 116 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.5 Interrupt Exception Handling Vector Table and Priority Table 6.4 lists interrupt sources and their vector numbers, vector table address offsets, and interrupt priorities. Each interrupt source is allocated a different vector number and vector table address offset. Vector table addresses are calculated from the vector numbers and vector table address offsets. In interrupt exception handling, the interrupt exception service routine start address is fetched from the vector table indicated by the vector table address. For details of calculation of the vector table address, see table 5.4 in section 5, Exception Handling. The priorities of IRQ interrupts and on-chip peripheral module interrupts can be set freely between 0 and 15 for each pin or module by setting interrupt priority registers 01, 02, and 05 to 15 (IPR01, IPR02, and IPR05 to IPR15). However, if two or more interrupts specified by the same IPR among IPR05 to IPR15 occur, the priorities are defined as shown in the IPR setting unit internal priority of table 6.4, and the priorities cannot be changed. A power-on reset assigns priority level 0 to IRQ interrupts and on-chip peripheral module interrupts. If the same priority level is assigned to two or more interrupt sources and interrupts from those sources occur simultaneously, they are processed by the default priorities indicated in table 6.4.

May. 08, 2008 Page 124 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.6 6.6.1 Operation Interrupt Operation Sequence The sequence of interrupt operations is described below. Figure 6.2 shows the operation flow. 1. The interrupt request sources send interrupt request signals to the interrupt controller. 2. The interrupt controller selects the highest-priority interrupt from the interrupt requests sent, following the priority levels set in interrupt priority registers 01, 02, and 05 to 15 (IPR01, IPR02, and IPR05 to IPR15). Lower priority interrupts are ignored*. If two of these interrupts have the same priority level or if multiple interrupts occur within a single IPR, the interrupt with the highest priority is selected, according to the default priority and IPR setting unit internal priority shown in table 6.4. 3. The priority level of the interrupt selected by the interrupt controller is compared with the interrupt level mask bits (I3 to I0) in the status register (SR) of the CPU. If the interrupt request priority level is equal to or less than the level set in bits I3 to I0, the interrupt request is ignored. If the interrupt request priority level is higher than the level in bits I3 to I0, the interrupt controller accepts the interrupt and sends an interrupt request signal to the CPU. 4. When the interrupt controller accepts an interrupt, a low level is output from the IRQOUT pin. 5. The CPU detects the interrupt request sent from the interrupt controller when the CPU decodes the instruction to be executed. Instead of executing the decoded instruction, the CPU starts interrupt exception handling (figure 6.4). 6. The interrupt exception service routine start address is fetched from the exception handling vector table corresponding to the accepted interrupt. 7. The status register (SR) is saved onto the stack, and the priority level of the accepted interrupt is copied to bits I3 to I0 in SR. 8. The program counter (PC) is saved onto the stack. 9. The CPU jumps to the fetched interrupt exception service routine start address and starts executing the program. The jump that occurs is not a delayed branch. 10. A high level is output from the IRQOUT pin. However, if the interrupt controller accepts an interrupt with a higher priority than the interrupt just being accepted, the IRQOUT pin holds low level. Rev. 2.00 May. 08, 2008 Page 125 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) Notes: The interrupt source flag should be cleared in the interrupt handler. After clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal to CPU" shown in table 6.5 is required before the interrupt source sent to the CPU is actually cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently accepted again, read the interrupt source flag after it has been cleared, and then execute an RTE instruction. * Interrupt requests that are designated as edge-sensing are held pending until the interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing the IRQ interrupt request register (IRQRR). For details, see section 6.4.4, IRQ Interrupts. Interrupts held pending due to edge-sensing are cleared by a power-on reset.

Assume that the bank number bit value in the bank number register (IBNR), BN, is i before the interrupt is generated. b. The contents of registers R0 to R14, GBR, MACH, MACL, and PR, and the interrupt vector table address offset (VTO) of the accepted interrupt are saved in the bank indicated by BN, bank i. c.

Rev. 2.00 May. 08, 2008 Page 137 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.8.3 Save and Restore Operations after Saving to All Banks If an interrupt occurs and usage of the register banks is enabled for the interrupt accepted by the CPU in a state where saving has been performed to all register banks, automatic saving to the stack is performed instead of register bank saving if the BOVE bit in the bank number register (IBNR) is cleared to 0. If the BOVE bit in IBNR is set to 1, register bank overflow exception occurs and data is not saved to the stack. Save and restore operations when using the stack are as follows: (1) Saving to Stack 1. The status register (SR) and program counter (PC) are saved to the stack during interrupt exception handling. 2. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are saved to the stack. The registers are saved to the stack in the order of MACL, MACH, GBR, PR, R14, R13, ..., R1, and R0. 3. The register bank overflow bit (BO) in SR is set to 1. 4. The bank number bit (BN) value in the bank number register (IBNR) remains set to the maximum value of 15. (2) Restoration from Stack When the RESBANK (restore from register bank) instruction is executed with the register bank overflow bit (BO) in SR set to 1, the CPU operates as follows: 1. The contents of the banked registers (R0 to R14, GBR, MACH, MACL, and PR) are restored from the stack. The registers are restored from the stack in the order of R0, R1, ..., R13, R14, PR, GBR, MACH, and MACL. 2. The bank number bit (BN) value in the bank number register (IBNR) remains set to the maximum value of 15. Rev. 2.00 May. 08, 2008 Page 138 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.8.4 Register Bank Exception There are two register bank exceptions (register bank errors): register bank overflow and register bank underflow. (1) Register Bank Overflow This exception occurs if, after data has been saved to all of the register banks, an interrupt for which register bank use is allowed is accepted by the CPU, and the BOVE bit in the bank number register (IBNR) is set to 1. In this case, the bank number bit (BN) value in the bank number register (IBNR) remains set to the bank count of 15 and saving is not performed to the register bank. (2) Register Bank Underflow This exception occurs if the RESBANK (restore from register bank) instruction is executed when no data has been saved to the register banks. In this case, the values of R0 to R14, GBR, MACH, MACL, and PR do not change. In addition, the bank number bit (BN) value in the bank number register (IBNR) remains set to 0. 6.8.5 Register Bank Error Exception Handling When a register bank error occurs, register bank error exception handling starts. When this happens, the CPU operates as follows: 1. The exception service routine start address which corresponds to the register bank error that occurred is fetched from the exception handling vector table. 2. The status register (SR) is saved to the stack. 3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the instruction to be executed after the last executed instruction for a register bank overflow, and the start address of the executed RESBANK instruction for a register bank underflow. To prevent multiple interrupts from occurring at a register bank overflow, the interrupt priority level that caused the register bank overflow is written to the interrupt mask level bits (I3 to I0) of the status register (SR). 4. Program execution starts from the exception service routine start address. Rev. 2.00 May. 08, 2008 Page 139 of 1200 REJ09B0344-0200 Section 6 Interrupt Controller (INTC) 6.9 Data Transfer with Interrupt Request Signals Interrupt request signals can be used to activate the DMAC and transfer data. Interrupt sources that are designated to activate the DMAC are masked without being input to the INTC. The mask condition is as follows: Mask condition = DME * (DE0 * interrupt source select 0 + DE1 * interrupt source select 1 + DE2 * interrupt source select 2 + DE3 * interrupt source select 3 + DE4 * interrupt source select 4 + DE5 * interrupt source select 5 + DE6 * interrupt source select 6 + DE7 * interrupt source select 7) Figure 6.13 shows a block diagram of interrupt control. Here, DME is bit 0 in DMAOR of the DMAC, and DEn (n = 0 to 7) is bit 0 in CHCR0 to CHCR7 of the DMAC. For details, see section 9, Direct Memory Access Controller (DMAC).

If, DMAC activating sources are selected, clear the DE bit to 0 for the relevant channel of the DMAC. 2. When interrupts occur, interrupt requests are sent to the CPU. 3. The CPU clears the interrupt source and performs the necessary processing in the interrupt exception service routine. 6.9.2 Handling Interrupt Request Signals as Sources for Activating DMAC but Not CPU Interrupt 1. Select DMAC activating sources and set both the DE and DME bits to 1. This masks CPU interrupt sources regardless of the interrupt priority register settings. 2. Activating sources are applied to the DMAC when interrupts occur. 3. The DMAC clears the interrupt sources when starting transfer. 6.10 6.10.1 Usage Note Timing to Clear an Interrupt Source The interrupt source flags should be cleared in the interrupt exception service routine. After clearing the interrupt source flag, "time from occurrence of interrupt request until interrupt controller identifies priority, compares it with mask bits in SR, and sends interrupt request signal to CPU" shown in table 6.5 is required before the interrupt source sent to the CPU is actually cancelled. To ensure that an interrupt request that should have been cleared is not inadvertently accepted again, read the interrupt source flag after it has been cleared, and then execute an RTE instruction.

These functions make it easy to design an effective self-monitoring debugger, enabling the chip to debug programs without using an in-circuit emulator. Instruction fetch or data read/write (bus master (CPU or DMAC) selection in the case of data read/write), data size, data contents, address value, and stop timing in the case of instruction fetch are break conditions that can be set in the UBC. Since this LSI uses a Harvard architecture, instruction fetch on the CPU bus (C bus) is performed by issuing bus cycles on the instruction fetch bus (F bus), and data access on the C bus is performed by issuing bus cycles on the memory access bus (M bus). The UBC monitors the C bus and internal bus (I bus). 7.1 Features 1. The following break comparison conditions can be set. Number of break channels: four channels (channels 0 to 3) User break can be requested as the independent condition on channels 0, 1, 2, and 3. * Address Comparison of the 32-bit address is maskable in 1-bit units. One of the three address buses (F address bus (FAB), M address bus (MAB), and I address bus (IAB)) can be selected. * Bus master when I bus is selected Selection of CPU cycles or DMAC cycles * Bus cycle Instruction fetch (only when C bus is selected) or data access * Read/write * Operand size Byte, word, and longword 2. Exception handling routine for user-specified break conditions can be executed. 3. In an instruction fetch cycle, it can be selected whether PC breaks are set before or after an instruction is executed. 4. When a break condition is satisfied, a trigger signal is output from the UBCTRG pin.

Rev. 2.00 May. 08, 2008 Page 165 of 1200 REJ09B0344-0200 Section 7 User Break Controller (UBC) 7.4 7.4.1 Operation Flow of the User Break Operation The flow from setting of break conditions to user break interrupt exception handling is described below: 1. The break address is set in a break address register (BAR). The masked address bits are set in a break address mask register (BAMR). The bus break conditions are set in the break bus cycle register (BBR). Three control bit groups of BBR (C bus cycle/I bus cycle select, instruction fetch/data access select, and read/write select) are each set. No user break will be generated if even one of these groups is set to 00. The relevant break control conditions are set in the bits of the break control register (BRCR). Make sure to set all registers related to breaks before setting BBR, and branch after reading from the last written register. The newly written register values become valid from the instruction at the branch destination. 2. In the case where the break conditions are satisfied, the UBC sends a user break interrupt request to the CPU, sets the C bus condition match flag (SCMFC) or I bus condition match flag (SCMFD) for the appropriate channel, and outputs a pulse to the UBCTRG pin with the width set by the CKS1 and CKS0 bits. Setting the UBID bit in BBR to 1 enables external monitoring of the trigger output without requesting user break interrupts. 3. On receiving a user break interrupt request signal, the INTC determines its priority. Since the user break interrupt has a priority level of 15, it is accepted when the priority level set in the interrupt mask level bits (I3 to I0) of the status register (SR) is 14 or lower. If the I3 to I0 bits are set to a priority level of 15, the user break interrupt is not accepted, but the conditions are checked, and condition match flags are set if the conditions match. For details on ascertaining the priority, see section 6, Interrupt Controller (INTC). 4. Condition match flags (SCMFC and SCMFD) can be used to check which condition has been satisfied. They are set when the conditions match, but are not reset. To use these flags again, write 0 to the corresponding bit of the flags. 5. It is possible that the breaks set in channels 0 to 3 occur around the same time. In this case, there will be only one user break request to the CPU, but these four break channel match flags may be set at the same time. 6. When selecting the I bus as the break condition, note as follows: Several bus masters, including the CPU and DMAC, are connected to the I bus. The UBC monitors bus cycles generated by the bus master specified by BBR, and determines the condition match. Rev. 2.00 May. 08, 2008 Page 166 of 1200 REJ09B0344-0200 Section 7 User Break Controller (UBC) I bus cycles (including read fill cycles) resulting from instruction fetches on the C bus by the CPU are defined as instruction fetch cycles on the I bus, while other bus cycles are defined as data access cycles. The DMAC only issues data access cycles for I bus cycles. If a break condition is specified for the I bus, even when the condition matches in an I bus cycle resulting from an instruction executed by the CPU, at which instruction the user break is to be accepted cannot be clearly defined. 7.4.2 Break on Instruction Fetch Cycle 1. When C bus/instruction fetch/read/word or longword is set in the break bus cycle register (BBR), the break condition is the FAB bus instruction fetch cycle. Whether PC breaks are set before or after the execution of the instruction can then be selected with the PCB0 or PCB1 bit of the break control register (BRCR) for the appropriate channel. If an instruction fetch cycle is set as a break condition, clear LSB in the break address register (BAR) to 0. A break cannot be generated as long as this bit is set to 1. 2. A break for instruction fetch which is set as a break before instruction execution occurs when it is confirmed that the instruction has been fetched and will be executed. This means a break does not occur for instructions fetched by overrun (instructions fetched at a branch or during an interrupt transition, but not to be executed). When this kind of break is set for the delay slot of a delayed branch instruction, the break is not generated until the execution of the first instruction at the branch destination. Note: If a branch does not occur at a delayed branch instruction, the subsequent instruction is not recognized as a delay slot. 3. When setting a break condition for break after instruction execution, the instruction set with the break condition is executed and then the break is generated prior to execution of the next instruction. As with pre-execution breaks, a break does not occur with overrun fetch instructions. When this kind of break is set for a delayed branch instruction and its delay slot, the break is not generated until the first instruction at the branch destination. 4. When an instruction fetch cycle is set, the break data register (BDR) is ignored. Therefore, break data cannot be set for the break of the instruction fetch cycle. 5. If the I bus is set for a break of an instruction fetch cycle, the setting is invalidated. Rev. 2.00 May. 08, 2008 Page 167 of 1200 REJ09B0344-0200 Section 7 User Break Controller (UBC) 7.4.3 Break on Data Access Cycle 1. If the C bus is specified as a break condition for data access break, condition comparison is performed for the virtual address accessed by the executed instructions, and a break occurs if the condition is satisfied. If the I bus is specified as a break condition, condition comparison is performed for the physical address of the data access cycles that are issued by the bus master specified by the bits to select the bus master of the I bus, and a break occurs if the condition is satisfied. For details on the CPU bus cycles issued on the I bus, see 6 in section 7.4.1, Flow of the User Break Operation. 2. The relationship between the data access cycle address and the comparison condition for each operand size is listed in table 7.3. Table 7.3 Data Access Cycle Addresses and Operand Size Comparison Conditions Address Compared Compares break address register bits 31 to 2 to address bus bits 31 to 2 Compares break address register bits 31 to 1 to address bus bits 31 to 1 Compares break address register bits 31 to 0 to address bus bits 31 to 0 Access Size Longword Word Byte This means that when address H'00001003 is set in the break address register (BAR), for example, the bus cycle in which the break condition is satisfied is as follows (where other conditions are met). Longword access at H'00001000 Word access at H'00001002 Byte access at H'00001003 3. If the data access cycle is selected, the instruction at which the break will occur cannot be determined.

If the C bus (FAB)/instruction fetch cycle is specified as a break condition, the instruction at which the break should occur can be uniquely determined. If the C bus/data access cycle or I bus/data access cycle is specified as a break condition, the instruction at which the break should occur cannot be uniquely determined. 1. When C bus (FAB)/instruction fetch (before instruction execution) is specified as a break condition: The address of the instruction that matched the break condition is saved to the stack. The instruction that matched the condition is not executed, and the break occurs before it. However when a delay slot instruction matches the condition, the instruction is executed, and the branch destination address is saved to the stack. 2. When C bus (FAB)/instruction fetch (after instruction execution) is specified as a break condition: The address of the instruction following the instruction that matched the break condition is saved to the stack. The instruction that matches the condition is executed, and the break occurs before the next instruction is executed. However when a delayed branch instruction or delay slot matches the condition, the instruction is executed, and the branch destination address is saved to the stack. 3. When C bus/data access cycle or I bus/data access cycle is specified as a break condition: The address after executing several instructions of the instruction that matched the break condition is saved to the stack.

The CPU can read from or write to the UBC registers via the I bus. Accordingly, during the period from executing an instruction to rewrite the UBC register till the new value is actually rewritten, the desired break may not occur. In order to know the timing when the UBC register is changed, read from the last written register. Instructions after then are valid for the newly written register value. 2. The UBC cannot monitor access to the C bus and I bus cycles in the same channel. 3. When a user break interrupt request and another exception source occur at the same instruction, which has higher priority is determined according to the priority levels defined in table 5.1 in section 5, Exception Handling. If an exception source with higher priority occurs, the user break interrupt request is not received. 4. Note the following when a break occurs in a delay slot. If a pre-execution break is set at a delay slot instruction, the user break interrupt request is not received immediately before execution of the branch destination. 5. User breaks are disabled during UBC module standby mode. Do not read from or write to the UBC registers during UBC module standby mode; the values are not guaranteed. 6. Do not set an address within an interrupt exception handling routine whose interrupt priority level is at least 15 (including user break interrupts) as a break address. 7. Do not set break after instruction execution for the SLEEP instruction or for the delayed branch instruction where the SLEEP instruction is placed at its delay slot. 8. When setting a break for a 32-bit instruction, set the address where the upper 16 bits are placed. If the address of the lower 16 bits is set and a break before instruction execution is set as a break condition, the break is handled as a break after instruction execution. 9. Do not set a user break before instruction execution for the instruction following the DIVU or DIVS instruction. If a user break before instruction execution is set for the instruction following the DIVU or DIVS instruction and an exception or interrupt occurs during execution of the DIVU or DIVS instruction, a user break occurs before instruction execution even though execution of the DIVU or DIVS instruction is halted. 10. Do not set a user break both before instruction execution and after instruction execution for instruction of the same address. If, for example, a user break before instruction execution on channel 0 and a user break after instruction on channel 1 are set at the instruction of the same address, the condition match flag for the channel 1 is set even though a user break on channel 0 occurs before instruction execution.

BSC functions enable this LSI to connect directly with SRAM, SDRAM, and other memory storage devices, and external devices. 8.1 Features The BSC has the following features. 1. External address space A maximum of 64 Mbytes for each of areas CS0 to CS7. Can specify the normal space interface, SRAM interface with byte selection, burst ROM (clock synchronous or asynchronous), MPX-I/O, and SDRAM for each address space. Can select the data bus width (8 or 16 bits) for each address space. Controls insertion of wait cycles for each address space. Controls insertion of wait cycles for each read access and write access. Can set independent idle cycles during the continuous access for five cases: read-write (in same space/different spaces), read-read (in same space/different spaces), the first cycle is a write access. 2. Normal space interface Supports the interface that can directly connect to the SRAM. 3. Burst ROM interface (clock asynchronous) High-speed access to the ROM that has the page mode function. 4. MPX-I/O interface Can directly connect to a peripheral LSI that needs an address/data multiplexing. 5. SDRAM interface Can set the SDRAM in up to two areas. Multiplex output for row address/column address. Efficient access by single read/single write. High-speed access in bank-active mode. Supports an auto-refresh and self-refresh. Supports low-frequency and power-down modes. Issues MRS and EMRS commands. Rev. 2.00 May. 08, 2008 Page 175 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) 6. SRAM interface with byte selection Can connect directly to a SRAM with byte selection. 7. Burst ROM interface (clock synchronous) Can connect directly to a ROM of the clock-synchronous type. 8. Bus arbitration Shares all of the resources with other CPU and outputs the bus enable after receiving the bus request from external devices. 9. Refresh function Supports the auto-refresh and self-refresh functions. Specifies the refresh interval using the refresh counter and clock selection. Can execute concentrated refresh by specifying the refresh counts (1, 2, 4, 6, or 8). 10. Usage as interval timer for refresh counter Generates an interrupt request at compare match.

Otherwise, the correct operation cannot be guaranteed. 8.3.2 Setting Operating Modes This LSI can set the following modes of operation at the time of power-on reset using the external pins. * Single-Chip Mode In single-chip mode, no access is made to the external bus, and the LSI is activated by the onchip ROM program upon a power-on reset. The BSC module enters the module standby state to reduce power consumption. * On-Chip ROM-Enabled Mode/On-Chip ROM-Disabled Mode In on-chip ROM-enabled mode, since the first half of area 0 is allocated to the on-chip ROM, the LSI can be activated by the on-chip ROM program upon a power-on reset. The second half of area 0 is the external memory space. Rev. 2.00 May. 08, 2008 Page 180 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) In on-chip ROM-disabled mode, the LSI is activated by the program stored in the external memory allocated to area 0. The second half of area 0 is the external memory space. In this case, a ROM is assumed for the external memory of area 0. Therefore, minimum functions are provided for the pins including address bus, data bus, CS0, and RD. Although BS, RDWR, WEn, and other pins are shown in the examples of access waveforms in this section, these are examples when pin settings are performed by the pin function controller. For details, see section 19, Pin Function Controller (PFC). Do not perform any operation except for area 0 read access until the pin settings by the program is completed. * Initial Settings of Data Bus Widths for Areas 0 to 7 The initial settings of data bus widths of areas 0 to 7 can be selected at a time as 8 or 16 bits. In on-chip ROM-disabled mode, the data bus width of area 0 cannot be changed from its initial setting after a power-on reset, but the data bus widths of areas 1 to 7 can be changed by register settings in the program. In on-chip ROM-enabled mode, all the data bus widths of areas 0 to 7 can be changed by register settings in the program. Note that data bus widths will be restricted depending on memory types. * Initial Settings of Endianness The initial settings of byte-data alignment of areas 0 to 7 can be selected as big endian or little endian. In on-chip ROM-disabled mode, the endianness of area 0 cannot be changed from its initial setting after a power-on reset, but the endianness of areas 1 to 7 can be changed by register settings in the program. In on-chip ROM-enabled mode, all the endianness of areas 0 to 7 can be changed by register settings in the program. Little endian cannot be selected in area 0. Since both 32-bit and 16-bit accesses are included in instruction fetches, no instructions can be assigned in little endian area. Accordingly, instructions should be executed in big endian area. For details of mode settings, see section 3, MCU Operating Modes.

When RTCOR matches RTCNT, the CMF bit in RTCSR is set to 1 and RTCNT is cleared to 0. When the RFSH bit in SDCR is 1, a memory refresh request is issued by this matching signal. This request is maintained until the refresh operation is performed. If the request is not processed when the next matching occurs, the previous request is ignored. The REFOUT signal can be asserted when a refresh request is generated while the bus is released. For details, see the description of Relationship between Refresh Requests and Bus Cycles in section 8.5.6 (9), Relationship between Refresh Requests and Bus Cycles, and section 8.5.11, Bus Arbitration. When the CMIE bit in RTCSR is set to 1, an interrupt request is issued by this matching signal. The request continues to be output until the CMF bit in RTCSR is cleared. Clearing the CMF bit only affects the interrupt request and does not clear the refresh request. Therefore, a combination of refresh request and interval timer interrupt can be specified so that the number of refresh requests are counted by using timer interrupts while refresh is performed periodically. When RTCOR is written, the upper 16 bits of the write data must be H'A55A to cancel write protection. This register is initialized to H'00000000 by a power-on reset and retains the value by a manual reset and in software standby mode.

In on-chip ROMenabled mode, endian can be set by the CSnBCR setting in a space of areas 0 to 7. Two data bus widths (8 bits and 16 bits) are available for normal memory and SRAM with byte selection. Only 16-bit data bus width is available for SDRAM. For MPX-I/O, the data bus width is fixed at 8 bits or 16 bits, or 8 bits or 16 bits can be selected by the access address. Data alignment is performed in accordance with the data bus width of the device. This also means that when longword data is read from a byte-width device, the read operation must be done four times. In this LSI, data alignment and conversion of data length is performed automatically between the respective interfaces. Tables 8.5 to 8.8 show the relationship between device data width and access unit. Note that addresses corresponding to the strobe signals for the 16-bit bus width differ between big endian and little endian. WE1 indicates the 0 address in big-endian mode, but WE0 indicates the 0 address in little-endian mode.

When using SRAM with a byte-selection pin, see section 8.5.8, SRAM Interface with Byte Selection. Figure 8.2 shows the basic timings of normal space access. A no-wait normal access is completed in two cycles. The BS signal is asserted for one cycle to indicate the start of a bus cycle.

When writing, only the WEn signal for the byte to be written is asserted. It is necessary to output the data that has been read using RD when a buffer is established in the data bus. The RD/WR signal is in a read state (high output) when no access has been carried out. Therefore, care must be taken when controlling the external data buffer, to avoid collision. Figures 8.3 and 8.4 show the basic timings of normal space access. If the WM bit in CSnWCR is cleared to 0, a Tnop cycle is inserted after the CSn space access to evaluate the external wait (figure 8.3). If the WM bit in CSnWCR is set to 1, external waits are ignored and no Tnop cycle is inserted (figure 8.4).

The number of cycles from RD, WEn negation to CSn negation can be specified by setting bits HW1 and HW0. Therefore, a flexible interface to an external device can be obtained. Figure 8.9 shows an example. A Th cycle and a Tf cycle are added before and after an ordinary cycle, respectively. In these cycles, RD and WEn are not asserted, while other signals are asserted. The data output is prolonged to the Tf cycle, and this prolongation is useful for devices with slow writing operations.

In the MPX space, CS5, AH, RD, and WEn signals control the accessing. The basic access for the MPX space consists of 2 cycles of address output followed by an access to a normal space. The bus width for the address output cycle or the data input/output cycle is fixed to 8 bits or 16 bits. Alternatively, it can be 8 bits or 16 bits depending on the address to be accessed. Output of the addresses D15 to D0 or D7 to D0 is performed from cycle Ta2 to cycle Ta3. Because cycle Ta1 has a high-impedance state, collisions of addresses and data can be avoided without inserting idle cycles, even in continuous access cycles. Address output is increased to 3 cycles by setting the MPXW bit in CS5WCR to 1. The RD/WR signal is output at the same time as the CS5 signal; it is high in the read cycle and low in the write cycle. The data cycle is the same as that in a normal space access. Timing charts are shown in figures 8.10 to 8.12.

The control signals for direct connection of SDRAM are RASL, CASL, RD/WR, DQMUL, DQMLL, CKE, CS2, and CS3. All the signals other than CS2 and CS3 are common to all areas, and signals other than CKE are valid when CS2 or CS3 is asserted. SDRAM can be connected to up to 2 spaces. The data bus width of the area that is connected to SDRAM can be set to 16 bits only. Burst read/single write (burst length 1) and burst read/burst write (burst length 1) are supported as SDRAM operating mode. Commands for SDRAM can be specified by RASL, CASL, RD/WR, and specific address signals. These commands supports: * NOP * Auto-refresh (REF) * Self-refresh (SELF) * All banks pre-charge (PALL) * Specified bank pre-charge (PRE) * Bank active (ACTV) * Read (READ) * Read with pre-charge (READA) * Write (WRIT) * Write with pre-charge (WRITA) * Write mode register (MRS, EMRS) The byte to be accessed is specified by DQMUL and DQMLL. Reading or writing is performed for a byte whose corresponding DQMxx is low. For details on the relationship between DQMxx and the byte to be accessed, see section 8.5.1, Endian/Access Size and Data Alignment. Figure 8.13 shows an example of the connection of the SDRAM with the LSI.

Tables 8.9 to 8.11 show the relationship between the settings of bits BSZ[1:0], A2ROW[1:0], A2COL[1:0], A3ROW[1:0], and A3COL[1:0] and the bits output at the address pins. Do not specify those bits in the manner other than this table, otherwise the operation of this LSI is not guaranteed. A29 to A18 are not multiplexed and the original values of address are always output at these pins. The A0 pin of SDRAM specifies a word address. Therefore, connect the A0 pin of SDRAM to the A1 pin of the LSI; then connect the A1 pin of SDRAM to the A2 pin of the LSI, and so on.

For example, read access of burst length 1 is performed consecutively 8 times to read 16-byte continuous data from the SDRAM that is connected to a 16-bit data bus. This access is called the burst read with the burst number 8. Table 8.12 shows the relationship between the access size and the number of bursts. Table 8.12 Relationship between Access Size and Number of Bursts Bus Width 16 bits Access Size 8 bits 16 bits 32 bits 16 bits Number of Bursts 1 1 2 8 Figures 8.14 and 8.15 show a timing chart in burst read. In burst read, an ACTV command is output in the Tr cycle, the READ command is issued in the Tc1, Tc2, and Tc3 cycles, the READA command is issued in the Tc4 cycle, and the read data is received at the rising edge of the external clock (CK) in the Td1 to Td4 cycles. The Tap cycle is used to wait for the completion of an autoprecharge induced by the READA command in the SDRAM. In the Tap cycle, a new command will not be issued to the same bank. However, access to another CS space or another bank in the same SDRAM space is enabled. The number of Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR. In this LSI, wait cycles can be inserted by specifying each bit in CS3WCR to connect the SDRAM in variable frequencies. Figure 8.15 shows an example in which wait cycles are inserted. The number of cycles from the Tr cycle where the ACTV command is output to the Tc1 cycle where the READ command is output can be specified using the WTRCD1 and WTRCD0 bits in CS3WCR. If the WTRCD1 and WTRCD0 bits specify one cycles or more, a Trw cycle where the NOT command is issued is inserted between the Tr cycle and Tc1 cycle. The number of cycles from the Tc1 cycle where the READ command is output to the Td1 cycle where the read data is latched can be specified for the CS2 and CS3 spaces independently, using the A2CL1 and A2CL0 bits in CS2WCR or the A3CL1 and A3CL0 bits in CS3WCR and WTRCD0 bit in CS3WCR. The number of cycles from Tc1 to Td1 corresponds to the SDRAM CAS latency. The CAS latency for the SDRAM is normally defined as up to three cycles. However, the CAS latency in this LSI can Rev. 2.00 May. 08, 2008 Page 251 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) be specified as 1 to 4 cycles. This CAS latency can be achieved by connecting a latch circuit between this LSI and the SDRAM. A Tde cycle is an idle cycle required to transfer the read data into this LSI and occurs once for every burst read or every single read.

For example, write access of burst length 1 is performed continuously 8 times to write 16-byte continuous data to the SDRAM that is connected to a 16-bit data bus. This access is called burst write with the burst number 8. The relationship between the access size and the number of bursts is shown in table 8.12. Figure 8.17 shows a timing chart for burst writes. In burst write, an ACTV command is output in the Tr cycle, the WRIT command is issued in the Tc1, Tc2, and Tc3 cycles, and the WRITA command is issued to execute an auto-precharge in the Tc4 cycle. In the write cycle, the write data is output simultaneously with the write command. After the write command with the autoprecharge is output, the Trw1 cycle that waits for the auto-precharge initiation is followed by the Tap cycle that waits for completion of the auto-precharge induced by the WRITA command in the SDRAM. Between the Trwl and the Tap cycle, a new command will not be issued to the same bank. However, access to another CS space or another bank in the same SDRAM space is enabled. The number of Trw1 cycles is specified by the TRWL1 and TRWL0 bits in CS3WCR. The number of Tap cycles is specified by the WTRP1 and WTRP0 bits in CS3WCR.

When the BACTV bit in SDCR is 1, access is performed using commands without auto-precharge (READ or WRIT). This function is called bank-active function. This function is valid only for either the upper or lower bits of area 3. When area 3 is set to bank-active mode, area 2 should be set to normal space or SRAM with byte selection. When areas 2 and 3 are both set to SDRAM or both the upper and lower bits of area 3 are connected to SDRAM, auto-precharge mode must be set. When the bank-active function is used, precharging is not performed when the access ends. When accessing the same row address in the same bank, it is possible to issue the READ or WRIT command immediately, without issuing an ACTV command. As SDRAM is internally divided into several banks, it is possible to activate one row address in each bank. If the next access is to a different row address, a PRE command is first issued to precharge the relevant bank, then when precharging is completed, the access is performed by issuing an ACTV command followed by a READ or WRIT command. If this is followed by an access to a different row address, the access time will be longer because of the precharging performed after the access request is issued. The number of cycles between issuance of the PRE command and the ACTV command is determined by the WTRP1 and WTPR0 bits in CS3WCR. In a write, when an auto-precharge is performed, a command cannot be issued to the same bank for a period of Trwl + Tap cycles after issuance of the WRITA command. When bank active mode is used, READ or WRIT commands can be issued successively if the row address is the same. The number of cycles can thus be reduced by Trwl + Tap cycles for each write. There is a limit on tRAS, the time for placing each bank in the active state. If there is no guarantee that there will not be a cache hit and another row address will be accessed within the period in which this value is maintained by program execution, it is necessary to set auto-refresh and set the refresh cycle to no more than the maximum value of tRAS. A burst read cycle without auto-precharge is shown in figure 8.19, a burst read cycle for the same row address in figure 8.20, and a burst read cycle for different row addresses in figure 8.21. Similarly, a burst write cycle without auto-precharge is shown in figure 8.22, a burst write cycle for the same row address in figure 8.23, and a burst write cycle for different row addresses in figure 8.24. In figure 8.20, a Tnop cycle in which no operation is performed is inserted before the Tc cycle that issues the READ command. The Tnop cycle is inserted to acquire two cycles of CAS latency for the DQMxx signal that specifies the read byte in the data read from the SDRAM. If the CAS Rev. 2.00 May. 08, 2008 Page 258 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) latency is specified as two cycles or more, the Tnop cycle is not inserted because the two cycles of latency can be acquired even if the DQMxx signal is asserted after the Tc cycle. When bank active mode is set, if only access cycles to the respective banks in the area 3 space are considered, as long as access cycles to the same row address continue, the operation starts with the cycle in figure 8.19 or 8.23, followed by repetition of the cycle in figure 8.20 or 8.23. An access to a different area during this time has no effect. If there is an access to a different row address in the bank active state, after this is detected the bus cycle in figure 8.20 or 8.23 is executed instead of that in figure 8.21 or 8.24. In bank active mode, too, all banks become inactive after a refresh cycle or after the bus is released as the result of bus arbitration.

Auto-refreshing can be performed by clearing the RMODE bit to 0 and setting the RFSH bit to 1 in SDCR. A continuous refreshing can be performed by setting the RRC2 to RRC0 bits in RTCSR. If SDRAM is not accessed for a long period, self-refresh mode, in which the power consumption for data retention is low, can be activated by setting both the RMODE bit and the RFSH bit to 1. (a) Auto-refreshing Refreshing is performed at intervals determined by the input clock selected by bits CKS2 to CKS0 in RTCSR, and the value set by in RTCOR. The value of bits CKS2 to CKS0 in RTCOR should be set so as to satisfy the refresh interval stipulation for the SDRAM used. First make the settings for RTCOR, RTCNT, and the RMODE and RFSH bits in SDCR, then make the CKS2 to CKS0 and RRC2 to RRC0 settings. When the clock is selected by bits CKS2 to CKS0, RTCNT starts counting up from the value at that time. The RTCNT value is constantly compared with the RTCOR value, and if the two values are the same, a refresh request is generated and an autorefresh is performed for the number of times specified by the RRC2 to RRC0. At the same time, RTCNT is cleared to zero and the count-up is restarted. Figure 8.25 shows the auto-refresh cycle timing. After starting, the auto refreshing, PALL command is issued in the Tp cycle to make all the banks to pre-charged state from active state when some bank is being pre-charged. Then REF command is issued in the Trr cycle after inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR. A new command is not issued for the duration of the number of cycles specified by the WTRC1 and WTRC0 bits in CS3WCR after the Trr cycle. The WTRC1 and WTRC0 bits must be set so as to satisfy the SDRAM refreshing cycle time stipulation (tRC). An idle cycle is inserted between the Tp cycle and Trr cycle when the setting value of the WTRP1 and WTRP0 bits in CS3WCR is longer than or equal to 1 cycle.

Self-refreshing is activated by setting both the RMODE bit and the RFSH bit in SDCR to 1. After starting the self-refreshing, PALL command is issued in Tp cycle after the completion of the pre-charging bank. A SELF command is then issued after inserting idle cycles of which number is specified by the WTRP1 and WTRP0 bits in CS3WSR. SDRAM cannot be accessed while in the self-refresh state. Self-refresh mode is cleared by clearing the RMODE bit to 0. After self-refresh mode has been cleared, command issuance is disabled for the number of cycles specified by the WTRC1 and WTRC0 bits in CS3WCR. Self-refresh timing is shown in figure 8.26. Settings must be made so that self-refresh clearing and data retention are performed correctly, and auto-refreshing is performed at the correct intervals. When self-refreshing is activated from the state in which auto-refreshing is set, or when exiting standby mode other than through a power-on reset, auto-refreshing is restarted if the RFSH bit is set to 1 and the RMODE bit is cleared to 0 when self-refresh mode is cleared. If the transition from clearing of self-refresh mode to the start of auto-refreshing takes time, this time should be taken into consideration when setting the initial value of RTCNT. Making the RTCNT value 1 less than the RTCOR value will enable refreshing to be started immediately. After self-refreshing has been set, the self-refresh state continues even if the chip standby state is entered using the LSI standby function, and is maintained even after recovery from standby mode due to an interrupt. Note that the necessary signals such as CKE must be driven even in standby state by setting the HIZCNT bit in CMNCR to 1. The self-refresh state is not cleared by a manual reset. In case of a power-on reset, the bus state controller's registers are initialized, and therefore the self-refresh state is cleared.

If a refresh request occurs while the bus is released by the bus arbitration function, the refresh will not be executed until the bus mastership is acquired. This LSI has the REFOUT pin to request the bus while waiting for refresh execution. For REFOUT pin function selection, see section 19, Pin Function Controller (PFC). This LSI continues to assert REFOUT (low level) until the bus is acquired. On receiving the asserted REFOUT signal, the external device must negate the BREQ signal and return the bus. If the external bus does not return the bus for a period longer than the specified refresh interval, refresh cannot be executed and the SDRAM contents may be lost. If a new refresh request occurs while waiting for the previous refresh request, the previous refresh request is deleted. To refresh correctly, a bus cycle longer than the refresh interval or the bus mastership occupation must be prevented from occurring. If a bus mastership is requested during self-refresh, the bus will not be released until the refresh is completed. Rev. 2.00 May. 08, 2008 Page 269 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) (10) Low-Frequency Mode When the SLOW bit in SDCR is set to 1, output of commands, addresses, and write data, and fetch of read data are performed at a timing suitable for operating SDRAM at a low frequency. Figure 8.27 shows the access timing in low-frequency mode. In this mode, commands, addresses, and write data are output in synchronization with the falling edge of CK, which is half a cycle delayed than the normal timing. Read data is fetched at the rising edge of CK, which is half a cycle faster than the normal timing. This timing allows the hold time of commands, addresses, write data, and read data to be extended. If SDRAM is operated at a high frequency with the SLOW bit set to 1, the setup time of commands, addresses, write data, and read data are not guaranteed. Take the operating frequency and timing design into consideration when making the SLOW bit setting.

This power-down mode can effectively lower the power consumption in the non-access cycle. However, please note that if an access occurs in power-down mode, a cycle of overhead occurs because a cycle is needed to assert the CKE in order to cancel power-down mode.

This 100-s or longer period should be obtained by a power-on reset generating circuit or software. To perform SDRAM initialization correctly, the bus state controller registers must first be set, followed by a write to the SDRAM mode register. In SDRAM mode register setting, the address signal value at that time is latched by a combination of the CSn, RASL, CASL, and RD/WR signals. If the value to be set is X, the bus state controller provides for value X to be written to the SDRAM mode register by performing a write to address H'FFFC4000 + X for area 2 SDRAM, and to address H'FFFC5000 + X for area 3 SDRAM. In this operation the data is ignored, but the mode write is performed as a byte-size access. To set burst read/single write, CAS latency 2 to 3, wrap type = sequential, and burst length 1 supported by the LSI, arbitrary data is written in a bytesize access to the addresses shown in table 8.13. In this time 0 is output at the external address pins of A12 or later.

A PALL command (all bank pre-charge command) is firstly issued. A REF command (auto refresh command) is then issued 8 times. An MRS command (mode register write command) is finally issued. Idle cycles, of which number is specified by the WTRP1 and WTRP0 bits in CS3WCR, are inserted between the PALL and the first REF. Idle cycles, of which number is specified by the WTRC1 and WTRC0 bits in CS3WCR, are inserted between REF and REF, and between the 8th REF and MRS. Idle cycles, of which number is one or more, are inserted between the MRS and a command to be issued next. It is necessary to keep idle time of certain cycles for SDRAM before issuing PALL command after power-on. Refer to the manual of the SDRAM for the idle time to be needed. When the pulse width of the reset signal is longer than the idle time, mode register setting can be started immediately after the reset, but care should be taken when the pulse width of the reset signal is shorter than the idle time.

The differences between the low-power SDRAM and normal SDRAM are that partial refresh takes place that puts only a part of the SDRAM in the self-refresh state during the self-refresh function, and that power consumption is low during refresh under user conditions such as the operating temperature. The partial refresh is effective in systems in which there is data in a work area other than the specific area can be lost without severe repercussions. The low-power SDRAM supports the extension mode register (EMRS) in addition to the mode registers as the normal SDRAM. This LSI supports issuing of the EMRS command. The EMRS command is issued according to the conditions specified in table below. For example, if data H'0YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the CS3 space in the following sequence: PALL -> REF x 8 -> MRS -> EMRS. In this case, the MRS and EMRS issue addresses are H'0000XX0 and H'YYYYYYY, respectively. If data H'1YYYYYYY is written to address H'FFFC5XX0 in longword, the commands are issued to the CS3 space in the following sequence: PALL -> MRS -> EMRS.

This mode is effective in systems where all of the system memory areas are used as work areas. If the RMODE bit in the SDCR is set to 1 while the DEEP and RFSH bits in the SDCR are set to 1, the low-power SDRAM enters deep power-down mode. If the RMODE bit is cleared to 0, the CKE signal is pulled high to cancel deep power-down mode. Before executing an access after returning from deep power-down mode, the power-up sequence must be re-executed.

In a burst ROM (clock asynchronous) interface, basically the same access as the normal space is performed, but the 2nd and subsequent access cycles are performed only by changing the address, without negating the RD signal at the end of the 1st cycle. In the 2nd and subsequent access cycles, addresses are changed at the falling edge of the CK. For the 1st access cycle, the number of wait cycles specified by the W3 to W0 bits in CSnWCR is inserted. For the 2nd and subsequent access cycles, the number of wait cycles specified by the W1 to W0 bits in CSnWCR is inserted. In the access to the burst ROM (clock asynchronous), the BS signal is asserted only to the first access cycle. An external wait input is valid only to the first access cycle. In the single access or write access that does not perform the burst operation in the burst ROM (clock asynchronous) interface, access timing is same as a normal space. In addition, there are some restrictions on 16-byte write access. For details, see section 8.6, Usage Notes. Table 8.15 lists a relationship between bus width, access size, and the number of bursts. Figure 8.32 shows a timing chart. Table 8.15 Relationship between Bus Width, Access Size, and Number of Bursts Bus Width 8 bits Access Size 8 bits 16 bits 32 bits 16 bytes CSnWCR.

This interface has 16-bit data pins and accesses SRAMs having upper and lower byte selection pins, such as UB and LB. When the BAS bit in CSnWCR is cleared to 0 (initial value), the write access timing of the SRAM interface with byte selection is the same as that for the normal space interface. While in read access of a byte-selection SRAM interface, the byte-selection signal is output from the WEn pin, which is different from that for the normal space interface. The basic access timing is shown in figure 8.33. In write access, data is written to the memory according to the timing of the byteselection pin (WEn). For details, please refer to the Data Sheet for the corresponding memory. If the BAS bit in CSnWCR is set to 1, the WEn pin and RD/WR pin timings change. Figure 8.34 shows the basic access timing. In write access, data is written to the memory according to the timing of the write enable pin (RD/WR). The data hold timing from RD/WR negation to data write must be acquired by setting the HW1 and HW0 bits in CSnWCR. Figure 8.35 shows the access timing when a software wait is specified.

The burst ROM interface accesses the burst ROM in the same way as a normal space. This interface is valid only for area 0. In the first access cycle, wait cycles are inserted. In this case, the number of wait cycles to be inserted is specified by the W3 to W0 bits in CS0WCR. In the second and subsequent cycles, the number of wait cycles to be inserted is specified by the BW1 and BW0 bits in CS0WCR. While the burst ROM (clock synchronous) is accessed, the BS signal is asserted only for the first access cycle and an external wait input is also valid for the first access cycle. If the bus width is 16 bits, the burst length must be specified as 8. The burst ROM interface does not support the 8-bit bus width for the burst ROM. The burst ROM interface performs burst operations for all read access. For example, in a longword access over a 16-bit bus, valid 16-bit data is read two times and invalid 16-bit data is read six times. These invalid data read cycles increase the memory access time and degrade the program execution speed and DMA transfer speed. To prevent this problem, using 16-byte read by the DMA is recommended. The burst ROM interface performs write access in the same way as normal space access.

As a result of these collisions, the reliability of the device is low and malfunctions may occur. A function that avoids data collisions by inserting idle (wait) cycles between continuous access cycles has been newly added. The number of wait cycles between access cycles can be set by the WM bit in CSnWCR, bits IWW2 to IWW0, IWRWD2 to IWRWD0, IWRWS2 to IWRWS0, IWRRD2 to IWRRD0, and IWRRS2 to IWRRS 0 in CSnBCR, and bits DMAIW2 to DMAIW0 and DMAIWA in CMNCR. The conditions for setting the idle cycles between access cycles are shown below. 1. Continuous access cycles are write-read or write-write 2. Continuous access cycles are read-write for different spaces 3. Continuous access cycles are read-write for the same space 4. Continuous access cycles are read-read for different spaces 5. Continuous access cycles are read-read for the same space 6. Data output from an external device caused by DMA single address transfer is followed by data output from another device that includes this LSI (DMAIWA = 0) 7. Data output from an external device caused by DMA single address transfer is followed by any type of access (DMAIWA = 1) For the specification of the number of idle cycles between access cycles described above, refer to the description of each register. Besides the idle cycles between access cycles specified by the registers, idle cycles must be inserted to interface with the internal bus or to obtain the minimum pulse width for a multiplexed pin (WEn). The following gives detailed information about the idle cycles and describes how to estimate the number of idle cycles. The number of idle cycles on the external bus from CSn negation to CSn or CSm assertion is described below. There are eight conditions that determine the number of idle cycles on the external bus as shown in table 8.16. The effects of these conditions are shown in figure 8.38. Rev. 2.00 May. 08, 2008 Page 286 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) Table 8.16 Conditions for Determining Number of Idle Cycles No. Condition (1) DMAIW[2:0] in CMNCR Description Range Note When 0 is specified for the number of idle cycles, the DACK signal may be asserted continuously. This causes a discrepancy between the number of cycles detected by the device with DACK and the DMAC transfer count, resulting in a malfunction. Do not set 0 for the number of idle cycles between memory types which are not allowed to be accessed successively. These bits specify the number of 0 to 12 idle cycles for DMA single address transfer. This condition is effective only for single address transfer and generates idle cycles after the access is completed. (2) IW***[2:0] in CSnBCR These bits specify the number of 0 to 12 idle cycles for access other than single address transfer. The number of idle cycles can be specified independently for each combination of the previous and next cycles. For example, in the case where reading CS1 space followed by reading other CS space, the bits IWRRD[2:0] in CS1BCR should be set to B'100 to specify six or more idle cycles. This condition is effective only for access cycles other than single address transfer and generates idle cycles after the access is completed. (3) SDRAM-related These bits specify precharge 0 to 3 bits in completion and startup wait cycles CSnWCR and idle cycles between commands for SDRAM access. This condition is effective only for SDRAM access and generates idle cycles after the access is completed WM in CSnWCR This bit enables or disables external 0 or 1 WAIT pin input for the memory types other than SDRAM. When this bit is cleared to 0 (external WAIT enabled), one idle cycle is inserted to check the external WAIT pin input after the access is completed. When this bit is set to 1 (disabled), no idle cycle is generated. Specify these bits in accordance with the specification of the target SDRAM. (4) Rev. 2.00 May. 08, 2008 Page 287 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) No. Condition (5) Read data transfer cycle Description Range Note One idle cycle is always generated after a read cycle with SDRAM interface. One idle cycle is inserted after a 0 or 1 read access is completed. This idle cycle is not generated for the first or middle cycles in divided access cycles. This is neither generated when the HM[1:0] bits in CSnWCR are not B'00. (6) Internal bus External bus access requests from 0 or idle cycles, etc. the CPU or DMAC and their results larger are passed through the internal bus. The external bus enters idle state during internal bus idle cycles or while a bus other than the external bus is being accessed. This condition is not effective for divided access cycles, which are generated by the BSC when the access size is larger than the external data bus width. Write data wait During write access, a write cycle is 0 or 1 cycles executed on the external bus only after the write data becomes ready. This write data wait period generates idle cycles before the write cycle. Note that when the previous cycle is a write cycle and the internal bus idle cycles are shorter than the previous write cycle, write data can be prepared in parallel with the previous write cycle and therefore, no idle cycle is generated (write buffer effect). Idle cycles between different memory types To ensure the minimum pulse width 0 to 2.5 on the signal-multiplexed pins, idle cycles may be inserted before access after memory types are switched. For some memory types, idle cycles are inserted even when memory types are not switched. The number of internal bus idle cycles may not become 0 depending on the I:B clock ratio. Tables 8.17 and 8.18 show the relationship between the clock ratio and the minimum number of internal bus idle cycles. (7) For write write or write read access cycles, successive access cycles without idle cycles are frequently available due to the write buffer effect described in the left column. If successive access cycles without idle cycles are not allowed, specify the minimum number of idle cycles between access cycles through CSnBCR. The number of idle cycles depends on the target memory types. See table 8.19. (8) Rev. 2.00 May. 08, 2008 Page 288 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) In the above conditions, a total of four conditions, that is, condition (1) or (2) (either one is effective), condition (3) or (4) (either one is effective), a set of conditions (5) to (7) (these are generated successively, and therefore the sum of them should be taken as one set of idle cycles), and condition (8) are generated at the same time. The maximum number of idle cycles among these four conditions become the number of idle cycles on the external bus. To ensure the minimum idle cycles, be sure to make register settings for condition (1) or (2).

Transfer is repeated in the following order: CS1 read CS1 read CS2 write CS2 write CS1 read ... * Conditions The bits for setting the idle cycles between access cycles in CS1BCR and CS2BCR are all set to 0. In CS1WCR and CS2WCR, the WM bit is set to 1 (external WAIT pin disabled) and the HW[1:0] bits are set to 00 (CS negation is not extended). I:B is set to 4:1, and no other processing is done during transfer. For both the CS1 and CS2 spaces, normal SRAM devices are connected, the bus width is 32 bits, and access size is also 32 bits. The idle cycles generated under each condition are estimated for each pair of access cycles. In the following table, R indicates a read cycle and W indicates a write cycle.

CSnBCR is set to 0. The WM bit is set to 1. Generated after a read cycle. See the I:B = 4:1 columns in table 8.17. No idle cycle is generated for the second time due to the write buffer effect. Note Figure 8.39 Comparison between Estimated Idle Cycles and Actual Value Rev. 2.00 May. 08, 2008 Page 292 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) 8.5.11 Bus Arbitration The bus arbitration of this LSI has the bus mastership in the normal state and releases the bus mastership after receiving a bus request from another device. Bus mastership is transferred at the boundary of bus cycles. Namely, bus mastership is released immediately after receiving a bus request when a bus cycle is not being performed. The release of bus mastership is delayed until the bus cycle is complete when a bus cycle is in progress. Even when from outside the LSI it looks like a bus cycle is not being performed, a bus cycle may be performing internally, started by inserting wait cycles between access cycles. Therefore, it cannot be immediately determined whether or not bus mastership has been released by looking at the CSn signal or other bus control signals. The states that do not allow bus mastership release are shown below. 1. Between the read and write cycles of a TAS instruction, or 64-bit transfer cycle of an FMOV instruction 2. Multiple bus cycles generated when the data bus width is smaller than the access size (for example, between bus cycles when longword access is made to a memory with a data bus width of 8 bits) 3. 16-byte transfer by the DMAC 4. Setting the BLOCK bit in CMNCR to 1 Moreover, by using DPRTY bit in CMNCR, whether the bus mastership request is received or not can be selected during DMAC burst transfer. The LSI has the bus mastership until a bus request is received from another device. Upon acknowledging the assertion (low level) of the external bus request signal BREQ, the LSI releases the bus at the completion of the current bus cycle and asserts the BACK signal. After the LSI acknowledges the negation (high level) of the BREQ signal that indicates the external device has released the bus, it negates the BACK signal and resumes the bus usage. With the SDRAM interface, all bank pre-charge commands (PALLs) are issued when active banks exist and the bus is released after completion of a PALL command. The bus sequence is as follows. The address bus and data bus are placed in a high-impedance state synchronized with the rising edge of CK. The bus mastership enable signal is asserted 0.5 cycles after the above timing, synchronized with the falling edge of CK. The bus control signals (BS, CSn, RASL, CASL, CKE, DQMxx, WEn, RD, and RD/WR) are placed in the high-impedance state at subsequent rising edges of CK. Bus request signals are sampled at the falling edge of CKIO. Note that CKE, RASL, and CASL can continue to be driven at the previous value even in the bus-released state by setting the HIZCNT bit in CMNCR. Rev. 2.00 May. 08, 2008 Page 293 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) The sequence for reclaiming the bus mastership from an external device is described below. 1.5 cycles after the negation of BREQ is detected at the falling edge of CK, the bus control signals are driven high. The bus acknowledge signal is negated at the next falling edge of the clock. The fastest timing at which actual bus cycles can be resumed after bus control signal assertion is at the rising edge of the CK where address and data signals are driven. Figure 8.40 shows the bus arbitration timing. When it is necessary to refresh SDRAM while releasing the bus mastership, the bus mastership should be returned using the REFOUT signal. For details on the selection of REFOUT, see section 19, Pin Function Controller (PFC). The REFOUT signal is kept asserting at low level until the bus mastership is acquired. The BREQ signal is negated by asserting the REFOUT signal and the bus mastership is returned from the external device. If the bus mastership is not returned for a refreshing period or longer, the contents of SDRAM cannot be guaranteed because a refreshing cannot be executed. While releasing the bus mastership, the SLEEP instruction (to enter sleep mode or standby mode), as well as a manual reset, cannot be executed until the LSI obtains the bus mastership. The BREQ input signal is ignored in standby mode and the BACK output signal is placed in the high impedance state. If the bus mastership request is required in this state, the bus mastership must be released by pulling down the BACK pin to enter standby mode. The bus mastership release (BREQ signal for high level negation) after the bus mastership request (BREQ signal for low level assertion) must be performed after the bus usage permission (BACK signal for low level assertion). If the BREQ signal is negated before the BACK signal is asserted, only one cycle of the BACK signal is asserted depending on the timing of the BREQ signal to be negated and this may cause a bus contention between the external device and the LSI.

At power-on reset, all signals are negated and data output buffers are turned off regardless of the bus cycle state after the internal reset is synchronized with the internal clock. All control registers are initialized. In standby, sleep, and manual reset, control registers of the bus state controller are not initialized. At manual reset, only the current bus cycle being executed is completed. Since the RTCNT continues counting up during manual reset signal assertion, a refresh request occurs to initiate the refresh cycle. (2) Access from the Side of the LSI Internal Bus Master Since the bus state controller (BSC) incorporates a one-stage write buffer, the BSC can execute an access via the internal bus before the previous external bus cycle is completed in a write cycle. If the on-chip module is read or written after the external low-speed memory is written, the on-chip module can be accessed before the completion of the external low-speed memory write cycle. In read cycles, the CPU is placed in the wait state until read operation has been completed. To continue the process after the data write to the device has been completed, perform a dummy read to the same address to check for completion of the write before the next process to be executed. The write buffer of the BSC functions in the same way for an access by a bus master other than the CPU such as the DMAC. Accordingly, to perform dual address DMA transfers, the next read cycle is initiated before the previous write cycle is completed. Note, however, that if both the DMA source and destination addresses exist in external memory space, the next write cycle will not be initiated until the previous write cycle is completed. Changing the registers in the BSC while the write buffer is operating may disrupt correct write access. Therefore, do not change the registers in the BSC immediately after a write access. If this change becomes necessary, do it after executing a dummy read of the write data. (3) On-Chip Peripheral Module Access Access to the on-chip peripheral module registers from the internal bus requires 2 or more cycles of the peripheral module clock (P). When the CPU writes to an on-chip peripheral register, however, the CPU can execute the following instructions without waiting for the register write to complete. This section describes the case where the system switches to software standby mode to reduce power consumption as an example. In this case, the code sets the STBCR register STBY bit to 1 Rev. 2.00 May. 08, 2008 Page 295 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) and then executes a SLEEP instruction. The code must, however, perform a dummy read of the STBCR register before executing the SLEEP instruction. If the dummy read is not performed, the CPU will execute the SLEEP instruction before the STBY bit is set to 1, and the system will not switch to the intended software standby mode, but rather will switch to sleep mode. The dummy read of the STBCR register is required to wait for the write to the STBY bit to complete. In other cases as well, application code should perform a dummy read of the same register after a register write instruction and only then execute the following instructions for the intended purpose to assure that the changes due to internal register writes are reflected when the following instructions are executed as in this example. The table below lists the number of access cycles required for CPU accesses to the on-chip peripheral module registers. Table 8.20 On-Chip Peripheral Module Register Access Cycle Counts Access Cycles Write Read (2+n) x I + (1+m) x B + 2 x P (2+n) x I + (1+m) x B + 2 x P + (2+I) x I Note: These are the numbers of cycles when the instruction is executed from internal ROM or internal RAM. When I:B is 1:1; n = 0, I = 0 When I:B is 2:1; n = 0 or 1, I = 1 When I:B is 4:1; n = 0 to 3, I = 2 When I:B is 8:1; n = 0 to 7, I = 2 When B:P is 1:1; m = 0 When B:P is 2:1; m = 0 or 1 When B:P is 4:1; m = 0 to 3 Note that n and m depend on the internal execution state. This product adopts synchronized logic and has a hierarchical bus structure. Data input and output for each of the busses is synchronized with the rising edge of the I clock for the C bus, the B clock for the I bus, and the P clock for the peripheral bus. Figure 8.41 shows an example of the write timing to the peripheral bus when the relationship between the clocks is I:B:P = 4:4:1. Data is output in synchronization with I to the C bus, to which the CPU is connected. When I:B is 1:1, 2 x I + B periods are required for data transfers from the C bus to the I bus. For transfers from the I bus to the peripheral bus when B:P is 4:1, since there are four clock cycles during a single P clock period, the timing with which the data is placed on the peripheral bus is as follows: there are four timings for P x 1, and up to 4 B periods are required for the P rising edge, which is the timing for transfers from the I bus to the Rev. 2.00 May. 08, 2008 Page 296 of 1200 REJ09B0344-0200 Section 8 Bus State Controller (BSC) peripheral bus (the example in figure 8.41 is for 4 x B). Therefore, when B:P is 4:1, data is transferred from the I bus to the peripheral bus in time (1+m) x B, where m = 0 to 3 periods. Note that the relationship between the timing with which the data appears on the I bus and the P rising edge depends on the program execution state. In figure 8.41, since n = 0 and m = 3, the access time will be 2 x I + 4 x B + 2 x P. I C bus B I bus P Peripheral bus (2+n) x I (1+m) x B 2 x P Figure 8.41 Internal Peripheral I/O Register Timing when I:B:P = 4:4:1 Figure 8.42 shows an example of the write timing to the peripheral bus when the relationship between the clocks is I:B:P = 4:2:1. Although transfers from the C bus to the peripheral bus are performed the same way for write, for read, the value read from the peripheral bus must be transferred to the CPU. Although the transfers from the peripheral bus to the I bus and from the I bus to the C bus are all performed on the corresponding bus clock rising edge, since I B P, (2 + 1) x I periods are actually required. In the example in figure 8.42, since n = 1, m = 1, and i = 1, the access period will be 3 x I + 2 x B + 2 x P + 3 x I.

The 16-bit bus width is used for the burst ROM interface (clock asynchronous). (The CSnBCR.TYPE[2:0] setting is B'001 and the CSnWCR.BSZ[1:0] setting is B'10) 2. The burst length is specified as 4. (The CSnWCR.BST[1:0] setting is B'10) 3. Write-back is performed with operand cache or 16-byte write access is performed with the DMAC for the burst ROM interface set as above.

Eight SCIF sources, two IIC3 sources, one A/D converter source, five MTU2 sources, and two CMT sources * Selectable bus modes Cycle steal mode (normal mode and intermittent mode) Burst mode * Selectable channel priority levels: The channel priority levels are selectable between fixed mode and round-robin mode. * Interrupt request: An interrupt request can be sent to the CPU on completion of half- or fulldata transfer. Through the HE and HIE bits in CHCR, an interrupt is specified to be issued to the CPU when half of the initially specified DMA transfer is completed. * External request detection: There are following four types of DREQ input detection. Low level detection High level detection Rising edge detection Falling edge detection Rev. 2.00 May. 08, 2008 Page 299 of 1200 REJ09B0344-0200 Section 9 Direct Memory Access Controller (DMAC) * Transfer request acknowledge and transfer end signals: Active levels for DACK and TEND can be set independently. * Support of reload functions in DMA transfer information registers: DMA transfer using the same information as the current transfer can be repeated automatically without specifying the information again. Modifying the reload registers during DMA transfer enables next DMA transfer to be done using different transfer information. The reload function can be enabled or disabled independently in each channel.

During a DMA transfer, these registers indicate the next source address. When the data of an external device with DACK is transferred in single address mode, SAR is ignored. To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary. SAR is initialized to H'00000000 by a reset and retains the value in software standby mode and module standby mode.

During a DMA transfer, these registers indicate the next destination address. When the data of an external device with DACK is transferred in single address mode, DAR is ignored. To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary. DAR is initialized to H'00000000 by a reset and retains the value in software standby mode and module standby mode.

The transfer count is 1 when the setting is H'00000001, 16,777,215 when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. During a DMA transfer, these registers indicate the remaining transfer count. The upper eight bits of DMATCR are always read as 0, and the write value should always be 0. To transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one. DMATCR is initialized to H'00000000 by a reset and retains the value in software standby mode and module standby mode.

When the reload function is enabled, the RDMATCR value is written to the transfer count register (DMATCR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer can be preset in RDMATCR during the current DMA transfer. When the reload function is disabled, RDMATCR is ignored. The upper eight bits of RDMATCR are always read as 0, and the write value should always be 0. As in DMATCR, the transfer count is 1 when the setting is H'00000001, 16,777,215 when H'00FFFFFF is set, and 16,777,216 (the maximum) when H'00000000 is set. To transfer data in 16 bytes, one 16-byte transfer (128 bits) counts one. RDMATCR is initialized to H'00000000 by a reset and retains the value in software standby mode and module standby mode.

However, transfer is enabled only when the TE bit in CHCR of the transfer corresponding channel, the NMIF bit in DMAOR, and the AE bit are all cleared to 0. Clearing the DME bit to 0 can terminate the DMA transfer on all channels. 0: DMA transfer is disabled on all channels 1: DMA transfer is enabled on all channels Note: * Only 0 can be written to clear the flag after 1 is read. If the priority mode bits are modified after a DMA transfer, the channel priority is initialized. If fixed mode 2 is specified, the channel priority is specified as CH0 > CH4 > CH1 > CH5 > CH2 > CH6 > CH3 > CH7. If fixed mode 1 is specified, the channel priority is specified as CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7. If round-robin mode is specified, the transfer end channel is reset. Table 9.3 show the priority change in each mode (modes 0 to 2) specified by the priority mode bits. In each priority mode, the channel priority to accept the next transfer request may change in up to three ways according to the transfer end channel. For example, when the transfer end channel is channel 1, the priority of the channel to accept the next transfer request is specified as CH2 > CH3 > CH0 >CH1 > CH4 > CH5 > CH6 > CH7. When the transfer end channel is any one of the channels 4 to 7, round-robin will not be applied and the priority level is not changed at the end of transfer in the channels 4 to 7.

Transfers can be requested in three modes: auto request, external request, and on-chip peripheral module request. In bus mode, burst mode or cycle steal mode can be selected. 9.4.1 Transfer Flow After the DMA source address registers (SAR), DMA destination address registers (DAR), DMA transfer count registers (DMATCR), DMA channel control registers (CHCR), DMA operation register (DMAOR), and DMA extension resource selector (DMARS) are set for the target transfer conditions, the DMAC transfers data according to the following procedure: 1. Checks to see if transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0) 2. When a transfer request comes and transfer is enabled, the DMAC transfers one transfer unit of data (depending on the TS0 and TS1 settings). For an auto request, the transfer begins automatically when the DE bit and DME bit are set to 1. The DMATCR value will be decremented by 1 for each transfer. The actual transfer flows vary by address mode and bus mode. 3. When half of the specified transfer count is exceeded (when DMATCR reaches half of the initial value), an HEI interrupt is sent to the CPU if the HIE bit in CHCR is set to 1. 4. When transfer has been completed for the specified count (when DMATCR reaches 0), the transfer ends normally. If the IE bit in CHCR is set to 1 at this time, a DEI interrupt is sent to the CPU. 5. When an address error in the DMAC or an NMI interrupt is generated, the transfer is terminated. Transfers are also terminated when the DE bit in CHCR or the DME bit in DMAOR is cleared to 0. Figure 9.2 is a flowchart of this procedure.

Transfers can be requested in three modes: auto request, external request, and on-chip peripheral module request. The request mode is selected by the RS[3:0] bits in CHCR_0 to CHCR_7 and DMARS0 to DMARS3. (1) Auto-Request Mode When there is no transfer request signal from an external source, as in a memory-to-memory transfer or a transfer between memory and an on-chip peripheral module unable to request a transfer, auto-request mode allows the DMAC to automatically generate a transfer request signal internally. When the DE bits in CHCR_0 to CHCR_7 and the DME bit in DMAOR are set to 1, the transfer begins so long as the TE bits in CHCR_0 to CHCR_7, and the AE and NMIF bits in DMAOR are 0. (2) External Request Mode In this mode a transfer is performed at the request signals (DREQ0 to DREQ3) of an external device. Choose one of the modes shown in table 9.5 according to the application system. When the DMA transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, NMIF = 0), DMA transfer is performed upon a request at the DREQ input.

After issuing acknowledge DACK signal for the accepted DREQ, the DREQ pin again enters the request accept enabled state. When DREQ is used by level detection, there are following two cases by the timing to detect the next DREQ after outputting DACK. Overrun 0: Transfer is terminated after the same number of transfer has been performed as requests. Overrun 1: Transfer is terminated after transfers have been performed for (the number of requests plus 1) times. The DO bit in CHCR selects this overrun 0 or overrun 1. Table 9.7 CHCR DO bit 0 1 External Request Overrun 0 Overrun 1 Selecting External Request Detection with DO Bit Rev. 2.00 May. 08, 2008 Page 330 of 1200 REJ09B0344-0200 Section 9 Direct Memory Access Controller (DMAC) (3) On-Chip Peripheral Module Request In this mode, the transfer is performed in response to the DMA transfer request signal from an onchip peripheral module. DMA transfer request signals from on-chip peripheral modules to the DMAC include transmit data empty and receive data full requests from the SCIF, A/D conversion end request from the A/D converter, compare match request from the CMT, and data transfer requests from the IIC3 and MTU2. When a transfer request signal is sent in on-chip peripheral module request mode while DMA transfer is enabled (DE = 1, DME = 1, TE = 0, AE = 0, and NMIF = 0), DMA transfer is performed. When the transmit data empty from the SCIF is selected, specify the transfer destination as the corresponding SCIF transmit data register. Likewise, when the receive data full from the SCIF is selected, specify the transfer source as the corresponding SCIF receive data register. When a transfer request is made by the A/D converter, the transfer source must be the A/D data register (ADDR). When the IIC3 transmit is selected as the transfer request, the transfer destination must be ICDRT; when the IIC3 reception is selected as the transfer request, the transfer source must be ICDRR. Any address can be specified for data transfer source and destination when a transfer request is sent from the CMT or MTU2.

Three modes (fixed mode 1, fixed mode 2, and round-robin mode) are selected using the PR1 and PR0 bits in DMAOR. (1) Fixed Mode In fixed modes, the priority levels among the channels remain fixed. There are two kinds of fixed modes as follows: Fixed mode 1: CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Fixed mode 2: CH0 > CH4 > CH1 > CH5 > CH2 > CH6 > CH3 > CH7 These are selected by the PR1 and PR0 bits in the DMA operation register (DMAOR). (2) Round-Robin Mode Each time one unit of word, byte, longword, or 16 bytes is transferred on one channel, the priority order is rotated. The channel on which the transfer was just finished is rotated to the lowest of the priority order among the four round-robin channels (channels 0 to 4). The priority of the channels other than the round-robin channels (channels 0 to 4) does not change even in round-robin mode. The round-robin mode operation is shown in figure 9.3. The priority in round-robin mode is CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 immediately after a reset. When round-robin mode has been specified, do not concurrently specify cycle steal mode and burst mode as the bus modes of any two or more channels.

The priority of channel 0, which was higher than channel 1, is also shifted. Priority order after transfer CH2 > CH3 > CH0 > CH1 > CH4 > CH5 > CH6 > CH7 (3) When channel 2 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order after transfer CH3 > CH0 > CH1 > CH2 > CH4 > CH5 > CH6 > CH7 Channel 2 is given the lowest priority among the round-robin channels. The priority of channels 0 and 1, which were higher than channel 2, is also shifted. If there is a transfer request only to channel 5 immediately after that, the priority does not change because channel 5 is not a round-robin channel. Post-transfer priority order when there is an immediate transfer request to channel 5 only CH3 > CH0 > CH1 > CH2 > CH4 > CH5 > CH6 > CH7 (4) When channel 7 transfers Initial priority order CH0 > CH1 > CH2 > CH3 > CH4 > CH5 > CH6 > CH7 Priority order does not change.

The DMAC operates as follows: 1. Transfer requests are generated simultaneously to channels 0 and 3. 2. Channel 0 has a higher priority, so the channel 0 transfer begins first (channel 3 waits for transfer). 3. A channel 1 transfer request occurs during the channel 0 transfer (channels 1 and 3 are both waiting) 4. When the channel 0 transfer ends, channel 0 is given the lowest priority among the round-robin channels. 5. At this point, channel 1 has a higher priority than channel 3, so the channel 1 transfer begins (channel 3 waits for transfer). 6. When the channel 1 transfer ends, channel 1 is given the lowest priority among the round-robin channels. 7. The channel 3 transfer begins. 8. When the channel 3 transfer ends, channels 3 and 2 are lowered in priority so that channel 3 is given the lowest priority among the round-robin channels.

They depend on the number of bus cycles of access to the transfer source and destination. A data transfer timing depends on the bus mode, which is cycle steal mode or burst mode. The DMAC supports the transfers shown in table 9.9.

The transfer source and destination can be located externally or internally. DMA transfer requires two bus cycles because data is read from the transfer source in a data read cycle and written to the transfer destination in a data write cycle. At this time, transfer data is temporarily stored in the DMAC. In the transfer between external memories as shown in figure 9.5, data is read to the DMAC from one external memory in a data read cycle, and then that data is written to the other external memory in a data write cycle. DMAC SAR Memory Address bus DAR Data bus Transfer source module Transfer destination module Data buffer The SAR value is an address, data is read from the transfer source module, and the data is tempolarily stored in the DMAC. First bus cycle DMAC SAR Memory Address bus DAR Data bus Transfer source module Transfer destination module Data buffer The DAR value is an address and the value stored in the data buffer in the DMAC is written to the transfer destination module. Second bus cycle Figure 9.5 Data Flow of Dual Address Mode Auto request, external request, and on-chip peripheral module request are available for the transfer request. DACK can be output in read cycle or write cycle in dual address mode. The AM bit in the channel control register (CHCR) can specify whether the DACK is output in read cycle or write cycle. Figure 9.6 shows an example of DMA transfer timing in dual address mode.

In this mode, the DMAC performs one DMA transfer in one bus cycle, accessing one of the external devices by outputting the DACK transfer request acknowledge signal to it, and at the same time outputting an address to the other device involved in the transfer. For example, in the case of transfer between external memory and an external device with DACK shown in figure 9.7, when the external device outputs data to the data bus, that data is written to the external memory in the same bus cycle. External address bus This LSI DMAC External memory External data bus External device with DACK DACK DREQ Data flow (from memory to device) Data flow (from device to memory) Figure 9.7 Data Flow in Single Address Mode Two kinds of transfer are possible in single address mode: (1) transfer between an external device with DACK and a memory-mapped external device, and (2) transfer between an external device with DACK and external memory. In both cases, only the external request signal (DREQ) is used for transfer requests. Figure 9.8 shows an example of DMA transfer timing in single address mode.

Select the mode by the TB bits in the channel control registers (CHCR). (a) Cycle Steal Mode * Normal mode In normal mode of cycle steal, the bus mastership is given to another bus master after a onetransfer-unit (byte, word, longword, or 16-byte unit) DMA transfer. When another transfer request occurs, the bus mastership is obtained from another bus master and a transfer is performed for one transfer unit. When that transfer ends, the bus mastership is passed to another bus master. This is repeated until the transfer end conditions are satisfied. The cycle-steal normal mode can be used for any transfer section; transfer request source, transfer source, and transfer destination. Figure 9.9 shows an example of DMA transfer timing in cycle-steal normal mode. Transfer conditions shown in the figure are; Dual address mode DREQ low level detection Rev. 2.00 May. 08, 2008 Page 340 of 1200 REJ09B0344-0200 Section 9 Direct Memory Access Controller (DMAC) DREQ Bus mastership returned to CPU once Bus cycle CPU CPU CPU DMAC DMAC Read/Write CPU DMAC DMAC CPU Read/Write Figure 9.9 DMA Transfer Example in Cycle-Steal Normal Mode (Dual Address, DREQ Low Level Detection) * Intermittent Mode 16 and Intermittent Mode 64 In intermittent mode of cycle steal, DMAC returns the bus mastership to other bus master whenever a unit of transfer (byte, word, longword, or 16 bytes) is completed. If the next transfer request occurs after that, DMAC obtains the bus mastership from other bus master after waiting for 16 or 64 cycles of B clock. DMAC then transfers data of one unit and returns the bus mastership to other bus master. These operations are repeated until the transfer end condition is satisfied. It is thus possible to make lower the ratio of bus occupation by DMA transfer than normal mode of cycle steal. The cycle-steal intermittent mode can be used for any transfer section; transfer request source, transfer source, and transfer destination. The bus modes, however, must be cycle steal mode in all channels. Figure 9.10 shows an example of DMA transfer timing in cycle-steal intermittent mode. Transfer conditions shown in the figure are; Dual address mode DREQ low level detection DREQ More than 16 or 64 B clock cycles (depends on the CPU's condition of using bus) Bus cycle CPU CPU CPU DMAC DMAC Read/Write CPU CPU DMAC DMAC Read/Write CPU Figure 9.10 Example of DMA Transfer in Cycle-Steal Intermittent Mode (Dual Address, DREQ Low Level Detection) Rev. 2.00 May. 08, 2008 Page 341 of 1200 REJ09B0344-0200 Section 9 Direct Memory Access Controller (DMAC) (b) Burst Mode In burst mode, once the DMAC obtains the bus mastership, it does not release the bus mastership and continues to perform transfer until the transfer end condition is satisfied. In external request mode with low level detection of the DREQ pin, however, when the DREQ pin is driven high, the bus mastership is passed to another bus master after the DMAC transfer request that has already been accepted ends, even if the transfer end conditions have not been satisfied.

Rev. 2.00 May. 08, 2008 Page 343 of 1200 REJ09B0344-0200 Section 9 Direct Memory Access Controller (DMAC) (4) Bus Mode and Channel Priority In priority fixed mode (CH0 > CH1), when channel 1 is transferring data in burst mode and a request arrives for transfer on channel 0, which has higher-priority, the data transfer on channel 0 will begin immediately. In this case, if the transfer on channel 0 is also in burst mode, the transfer on channel 1 will only resume on completion of the transfer on channel 0. When channel 0 is in cycle steal mode, one transfer-unit of data on this channel, which has the higher priority, is transferred. Data is then transferred continuously to channel 1 without releasing the bus. The bus mastership will then switch between the two in this order: channel 0, channel 1, channel 0, channel 1, etc. That is, the CPU cycle after the data transfer in cycle steal mode is replaced with a burst-mode transfer cycle (priority execution of burst-mode cycle). An example of this is shown in figure 9.12. When multiple channels are in burst mode, data transfer on the channel that has the highest priority is given precedence. When DMA transfer is being performed on multiple channels, the bus mastership is not released to another bus-master device until all of the competing burst-mode transfers have been completed.

When a setting is made so that the DMA transfer size is divided into multiple bus cycles and the CS signal is negated between bus cycles, note that DACK and TEND are divided like the CS signal for data alignment. Also, if the DREQ detection is set to level-detection mode (DS bit in CHCR = 0), the DREQ sampling may not be detected correctly with divided DACK, and one extra overrun may occur at maximum. Use a setting that does not divide DACK or specify a transfer size smaller than the external device bus width if DACK is divided. Figure 9.18 shows this example.

For the reload transfer count in RDMATCR, always set a value equal to the initial transfer count (the value in DMATCR). If the first setting of DMATCR differs from the RDMATCR setting used in the second and following DMA transfer, the half-end flag setting timing may be earlier than half of the transfer count or the half-end flag may not be set.

control the TCNT operation for each channel. The MTU2 has a total of eight TCR registers, one each for channels 0 to 4 and three (TCRU_5, TCRV_5, and TCRW_5) for channel 5. TCR register settings should be conducted only when TCNT operation is stopped.

See tables 10.4 and 10.5 for details. 4, 3 CKEG[1:0] 00 R/W Clock Edge 0 and 1 These bits select the input clock edge. When the input clock is counted using both edges, the input clock period is halved (e.g. P/4 both edges = P/2 rising edge). If phase counting mode is used on channels 1 and 2, this setting is ignored and the phase counting mode setting has priority. Internal clock edge selection is valid when the input clock is P/4 or slower. When P/1 or the overflow/underflow of another channel is selected for the input clock, although values can be written, counter operation compiles with the initial value. 00: Count at rising edge 01: Count at falling edge 1x: Count at both edges 2 to 0 TPSC[2:0] 000 R/W Time Prescaler 0 to 2 These bits select the TCNT counter clock. The clock source can be selected independently for each channel. See tables 10.6 to 10.10 for details.

The write value should always be 0. 10.3.2 Timer Mode Register (TMDR) The TMDR registers are 8-bit readable/writable registers that are used to set the operating mode of each channel. The MTU2 has five TMDR registers, one each for channels 0 to 4. TMDR register settings should be changed only when TCNT operation is stopped.

TGRF compare match is generated when TGRF is used as the buffer register. In channels 1 to 4, this bit is reserved. It is always read as 0 and the write value should always be 0. 0: TGRE_0 and TGRF_0 operate normally 1: TGRE_0 and TGRF_0 used together for buffer operation Rev. 2.00 May. 08, 2008 Page 366 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) Bit 5 Bit Name BFB Initial Value 0 R/W R/W Description Buffer Operation B Specifies whether TGRB is to operate in the normal way, or TGRB and TGRD are to be used together for buffer operation. When TGRD is used as a buffer register, TGRD input capture/output compare is not generated in a mode other than complementary PWM. TGRD compare match is generated in complementary PWM mode. When compare match occurs during the Tb period in complementary PWM mode, TGFD is set. Therefore, set the TGIED bit in the timer interrupt enable register 3/4 (TIER_3/4) to 0. In channels 1 and 2, which have no TGRD, bit 5 is reserved. It is always read as 0 and cannot be modified. 0: TGRB and TGRD operate normally 1: TGRB and TGRD used together for buffer operation 4 BFA 0 R/W Buffer Operation A Specifies whether TGRA is to operate in the normal way, or TGRA and TGRC are to be used together for buffer operation. When TGRC is used as a buffer register, TGRC input capture/output compare is not generated in a mode other than complementary PWM. TGRC compare match is generated when in complementary PWM mode. When compare match for channel 4 occurs during the Tb period in complementary PWM mode, TGFC is set. Therefore, set the TGIEC bit in the timer interrupt enable register 4 (TIER_4) to 0. In channels 1 and 2, which have no TGRC, bit 4 is reserved. It is always read as 0 and cannot be modified. 0: TGRA and TGRC operate normally 1: TGRA and TGRC used together for buffer operation 3 to 0 MD[3:0] 0000 R/W Modes 0 to 3 These bits are used to set the timer operating mode.

PWM mode 2 cannot be set for channels 3 and 4. 2. Phase counting mode cannot be set for channels 0, 3, and 4. 3. Reset synchronous PWM mode, complementary PWM mode can only be set for channel 3. When channel 3 is set to reset synchronous PWM mode or complementary PWM mode, the channel 4 settings become ineffective and automatically conform to the channel 3 settings. However, do not set channel 4 to reset synchronous PWM mode or complementary PWM mode. Reset synchronous PWM mode and complementary PWM mode cannot be set for channels 0, 1, and 2.

The MTU2 has a total of eleven TIOR registers, two each for channels 0, 3, and 4, one each for channels 1 and 2, and three (TIORU_5, TIORV_5, and TIORW_5) for channel 5. TIOR should be set while TMDR is set in normal operation, PWM mode, or phase counting mode. The initial output specified by TIOR is valid when the counter is stopped (the CST bit in TSTR is cleared to 0). Note also that, in PWM mode 2, the output at the point at which the counter is cleared to 0 is specified. When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register operates as a buffer register. * TIORH_0, TIOR_1, TIOR_2, TIORH_3, TIORH_4 Bit: 7 6 5 4 3 2 1 0 IOB[3:0] IOA[3:0] Initial value: 0 R/W: R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W 0 R/W Bit 7 to 4 Bit Name IOB[3:0] Initial Value 0000 R/W R/W Description I/O Control B0 to B3 Specify the function of TGRB.

TCNT performs up-counting, and is also capable of free-running operation, cycle counting, and external event counting. Each TGR can be used as an input capture register or output compare register. Always select MTU2 external pins set function using the pin function controller (PFC). (1) Counter Operation When one of bits CST0 to CST4 in TSTR or bits CSTU5, CSTV5, and CSTW5 in TSTR_5 is set to 1, the TCNT counter for the corresponding channel begins counting. TCNT can operate as a free-running counter, periodic counter, for example. (a) Example of Count Operation Setting Procedure Figure 10.4 shows an example of the count operation setting procedure. [1] Select the counter clock with bits TPSC2 to TPSC0 in TCR. At the same time, select the input clock edge with bits CKEG1 and CKEG0 in TCR. Free-running counter [2] For periodic counter operation, select the TGR to be used as the TCNT clearing source with bits CCLR2 to CCLR0 in TCR. [3] Designate the TGR selected in [2] as an output compare register by means of TIOR. [4] Set the periodic counter cycle in the TGR selected in [2].

When the relevant bit in TSTR is set to 1 the corresponding TCNT counter starts up-count operation as a free-running counter. When TCNT overflows (from H'FFFF to H'0000), the TCFV bit in TSR is set to 1. If the value of the corresponding TCIEV bit in TIER is 1 at this point, the MTU2 requests an interrupt. After overflow, TCNT starts counting up again from H'0000. Figure 10.5 illustrates free-running counter operation. TCNT value H'FFFF H'0000 Time CST bit TCFV Figure 10.5 Free-Running Counter Operation When compare match is selected as the TCNT clearing source, the TCNT counter for the relevant channel performs periodic count operation. The TGR register for setting the period is designated as an output compare register, and counter clearing by compare match is selected by means of bits CCLR0 to CCLR2 in TCR. After the settings have been made, TCNT starts up-count operation as a periodic counter when the corresponding bit in TSTR is set to 1. When the count value matches the value in TGR, the TGF bit in TSR is set to 1 and TCNT is cleared to H'0000. If the value of the corresponding TGIE bit in TIER is 1 at this point, the MTU2 requests an interrupt. After a compare match, TCNT starts counting up again from H'0000.

Rising edge, falling edge, or both edges can be selected as the detected edge. For channels 0 and 1, it is also possible to specify another channel's counter input clock or compare match signal as the input capture source. Note: When another channel's counter input clock is used as the input capture input for channels 0 and 1, P/1 should not be selected as the counter input clock used for input capture input. Input capture will not be generated if P/1 is selected. (a) Example of Input Capture Operation Setting Procedure Figure 10.10 shows an example of the input capture operation setting procedure.

Also, a number of TCNT counters can be cleared simultaneously by making the appropriate setting in TCR (synchronous clearing). Synchronous operation enables TGR to be incremented with respect to a single time base. Channels 0 to 4 can all be designated for synchronous operation. Channel 5 cannot be used for synchronous operation. (1) Example of Synchronous Operation Setting Procedure Figure 10.12 shows an example of the synchronous operation setting procedure.

In this example, synchronous operation and PWM mode 1 have been designated for channels 0 to 2, TGRB_0 compare match has been set as the channel 0 counter clearing source, and synchronous clearing has been set for the channel 1 and 2 counter clearing source. Three-phase PWM waveforms are output from pins TIOC0A, TIOC1A, and TIOC2A. At this time, synchronous presetting, and synchronous clearing by TGRB_0 compare match, are performed for channel 0 to 2 TCNT counters, and the data set in TGRB_0 is used as the PWM cycle.

In channel 0, TGRF can also be used as a buffer register. Buffer operation differs depending on whether TGR has been designated as an input capture register or as a compare match register. Note: TGRE_0 cannot be designated as an input capture register and can only operate as a compare match register. Table 10.43 shows the register combinations used in buffer operation.

The settings used in this example are TCNT clearing by compare match B, 1 output at compare match A, and 0 output at compare match B. In this example, the TTSA bit in TBTM is cleared to 0. As buffer operation has been set, when compare match A occurs the output changes and the value in buffer register TGRC is simultaneously transferred to timer general register TGRA. This operation is repeated each time that compare match A occurs. For details of PWM modes, see section 10.4.5, PWM Modes.

Counter clearing by TGRA input capture has been set for TCNT, and both rising and falling edges have been selected as the TIOCA pin input capture input edge. As buffer operation has been set, when the TCNT value is stored in TGRA upon the occurrence of input capture A, the value previously stored in TGRA is simultaneously transferred to TGRC.

Either compare match (initial setting) or TCNT clearing can be selected for the transfer timing. TCNT clearing as transfer timing is one of the following cases. * When TCNT overflows (H'FFFF to H'0000) * When H'0000 is written to TCNT during counting * When TCNT is cleared to H'0000 under the condition specified in the CCLR2 to CCLR0 bits in TCR Note: TBTM must be modified only while TCNT stops. Figure 10.19 shows an operation example in which PWM mode 1 is designated for channel 0 and buffer operation is designated for TGRA_0 and TGRC_0. The settings used in this example are TCNT_0 clearing by compare match B, 1 output at compare match A, and 0 output at compare match B. The TTSA bit in TBTM_0 is set to 1.

This function works by counting the channel 1 counter clock upon overflow/underflow of TCNT_2 as set in bits TPSC0 to TPSC2 in TCR. Underflow occurs only when the lower 16-bit TCNT is in phase counting mode. Table 10.44 shows the register combinations used in cascaded operation. Note: When phase counting mode is set for channel 1, the counter clock setting is invalid and the counters operates independently in phase counting mode. Table 10.44 Cascaded Combinations Combination Channels 1 and 2 Upper 16 Bits TCNT_1 Lower 16 Bits TCNT_2 For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional input capture input pins can be specified by the input capture control register (TICCR).

The output level can be selected as 0, 1, or toggle output in response to a compare match of each TGR. TGR registers settings can be used to output a PWM waveform in the range of 0% to 100% duty. Designating TGR compare match as the counter clearing source enables the period to be set in that register. All channels can be designated for PWM mode independently. Synchronous operation is also possible. There are two PWM modes, as described below. * PWM mode 1 PWM output is generated from the TIOCA and TIOCC pins by pairing TGRA with TGRB and TGRC with TGRD. The output specified by bits IOA0 to IOA3 and IOC0 to IOC3 in TIOR is output from the TIOCA and TIOCC pins at compare matches A and C, and the output specified by bits IOB0 to IOB3 and IOD0 to IOD3 in TIOR is output at compare matches B and D. The initial output value is the value set in TGRA or TGRC. If the set values of paired TGRs are identical, the output value does not change when a compare match occurs. In PWM mode 1, a maximum 8-phase PWM output is possible. * PWM mode 2 PWM output is generated using one TGR as the cycle register and the others as duty registers. The output specified in TIOR is performed by means of compare matches. Upon counter clearing by a synchronization register compare match, the output value of each pin is the initial value set in TIOR. If the set values of the cycle and duty registers are identical, the output value does not change when a compare match occurs. In PWM mode 2, a maximum 8-phase PWM output is possible in combination use with synchronous operation. The correspondence between PWM output pins and registers is shown in table 10.46.

This mode can be set for channels 1 and 2. When phase counting mode is set, an external clock is selected as the counter input clock and TCNT operates as an up/down-counter regardless of the setting of bits TPSC0 to TPSC2 and bits CKEG0 and CKEG1 in TCR. However, the functions of bits CCLR0 and CCLR1 in TCR, and of TIOR, TIER, and TGR, are valid, and input capture/compare match and interrupt functions can be used. This can be used for two-phase encoder pulse input. If overflow occurs when TCNT is counting up, the TCFV flag in TSR is set; if underflow occurs when TCNT is counting down, the TCFU flag is set. The TCFD bit in TSR is the count direction flag. Reading the TCFD flag reveals whether TCNT is counting up or down. Table 10.47 shows the correspondence between external clock pins and channels.

Channel 1 is set to phase counting mode 1, and the encoder pulse A-phase and B-phase are input to TCLKA and TCLKB. Channel 0 operates with TCNT counter clearing by TGRC_0 compare match; TGRA_0 and TGRC_0 are used for the compare match function and are set with the speed control period and position control period. TGRB_0 is used for input capture, with TGRB_0 and TGRD_0 operating in buffer mode. The channel 1 counter input clock is designated as the TGRB_0 input capture source, and the pulse widths of 2-phase encoder 4-multiplication pulses are detected. TGRA_1 and TGRB_1 for channel 1 are designated for input capture, and channel 0 TGRA_0 and TGRC_0 compare matches are selected as the input capture source and store the up/down-counter values for the control periods. This procedure enables the accurate detection of position and speed.

[3] When performing brushless DC motor control, set bit BDC in the timer gate control register (TGCR) and set the feedback signal input source and output chopping or gate signal direct output. [4] Set the dead time in TCNT_3. Set TCNT_4 to H'0000. Inter-channel synchronization setting [5] [5] Set only when restarting by a synchronous clear from another channel during complementary PWM mode operation. In this case, synchronize the channel generating the synchronous clear with channels 3 and 4 using the timer synchro register (TSYR). [6] Set the output PWM duty in the duty registers (TGRB_3, TGRA_4, TGRB_4) and buffer registers (TGRD_3, TGRC_4, TGRD_4). Set the same initial value in each corresponding TGR. [7] This setting is necessary only when no dead time should be generated. Make appropriate settings in the timer dead time enable register (TDER) so that no dead time is generated. [8] Set the dead time in the dead time register (TDDR), 1/2 the carrier cycle in the carrier cycle data register (TCDR) and carrier cycle buffer register (TCBR), and 1/2 the carrier cycle plus the dead time in TGRA_3 and TGRC_3. When no dead time generation is selected, set 1 in TDDR and 1/2 the carrier cycle + 1 in TGRA_3 and TGRC_3.

Figure 10.39 illustrates counter operation in complementary PWM mode, and figure 10.40 shows an example of complementary PWM mode operation. (a) Counter Operation In complementary PWM mode, three counters--TCNT_3, TCNT_4, and TCNTS--perform up/down-count operations. TCNT_3 is automatically initialized to the value set in TDDR when complementary PWM mode is selected and the CST bit in TSTR is 0. When the CST bit is set to 1, TCNT_3 counts up to the value set in TGRA_3, then switches to down-counting when it matches TGRA_3. When the TCNT3 value matches TDDR, the counter switches to up-counting, and the operation is repeated in this way. TCNT_4 is initialized to H'0000. When the CST bit is set to 1, TCNT4 counts up in synchronization with TCNT_3, and switches to down-counting when it matches TCDR. On reaching H'0000, TCNT4 switches to up-counting, and the operation is repeated in this way. TCNTS is a read-only counter. It need not be initialized. When TCNT_3 matches TCDR during TCNT_3 and TCNT_4 up/down-counting, down-counting is started, and when TCNTS matches TCDR, the operation switches to up-counting. When TCNTS matches TGRA_3, it is cleared to H'0000. When TCNT_4 matches TDDR during TCNT_3 and TCNT_4 down-counting, up-counting is started, and when TCNTS matches TDDR, the operation switches to down-counting. When TCNTS reaches H'0000, it is set with the value in TGRA_3. TCNTS is compared with the compare register and temporary register in which the PWM duty is set during the count operation only.

Figure 10.40 shows an example of complementary PWM mode operation. The registers which are constantly compared with the counters to perform PWM output are TGRB_3, TGRA_4, and TGRB_4. When these registers match the counter, the value set in bits OLSN and OLSP in the timer output control register (TOCR) is output. The buffer registers for these compare registers are TGRD_3, TGRC_4, and TGRD_4. Between a buffer register and compare register there is a temporary register. The temporary registers cannot be accessed by the CPU. Data in a compare register is changed by writing the new data to the corresponding buffer register. The buffer registers can be read or written at any time. The data written to a buffer register is constantly transferred to the temporary register in the Ta interval. Data is not transferred to the temporary register in the Tb interval. Data written to a buffer register in this interval is transferred to the temporary register at the end of the Tb interval. The value transferred to a temporary register is transferred to the compare register when TCNTS for which the Tb interval ends matches TGRA_3 when counting up, or H'0000 when counting down. The timing for transfer from the temporary register to the compare register can be selected with bits MD3 to MD0 in the timer mode register (TMDR). Figure 10.40 shows an example in which the mode is selected in which the change is made in the trough. In the tb interval (tb1 in figure 10.40) in which data transfer to the temporary register is not performed, the temporary register has the same function as the compare register, and is compared Rev. 2.00 May. 08, 2008 Page 477 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) with the counter. In this interval, therefore, there are two compare match registers for one-phase output, with the compare register containing the pre-change data, and the temporary register containing the new data. In this interval, the three counters--TCNT_3, TCNT_4, and TCNTS-- and two registers--compare register and temporary register--are compared, and PWM output controlled accordingly.

In addition, there is a register that specifies whether to generate dead time (it should be used only when dead time generation should be disabled). Before setting complementary PWM mode with bits MD3 to MD0 in the timer mode register (TMDR), the following initial register values must be set. TGRC_3 operates as the buffer register for TGRA_3, and should be set with 1/2 the PWM carrier cycle + dead time Td. The timer cycle buffer register (TCBR) operates as the buffer register for the timer cycle data register (TCDR), and should be set with 1/2 the PWM carrier cycle. Set dead time Td in the timer dead time data register (TDDR). When dead time is not needed, the TDER bit in the timer dead time enable register (TDER) should be cleared to 0, TGRC_3 and TGRA_3 should be set to 1/2 the PWM carrier cycle + 1, and TDDR should be set to 1. Set the respective initial PWM duty values in buffer registers TGRD_3, TGRC_4, and TGRD_4. The values set in the five buffer registers excluding TDDR are transferred simultaneously to the corresponding compare registers when complementary PWM mode is set. Set TCNT_4 to H'0000 before setting complementary PWM mode. Table 10.56 Registers and Counters Requiring Initialization Register/Counter TGRC_3 Set Value 1/2 PWM carrier cycle + dead time Td (1/2 PWM carrier cycle + 1 when dead time generation is disabled by TDER) TDDR TCBR TGRD_3, TGRC_4, TGRD_4 TCNT_4 Dead time Td (1 when dead time generation is disabled by TDER) 1/2 PWM carrier cycle Initial PWM duty value for each phase H'0000 Note: The TGRC_3 set value must be the sum of 1/2 the PWM carrier cycle set in TCBR and dead time Td set in TDDR. When dead time generation is disabled by TDER, TGRC_3 must be set to 1/2 the PWM carrier cycle + 1. Rev. 2.00 May. 08, 2008 Page 480 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) (d) PWM Output Level Setting In complementary PWM mode, the PWM pulse output level is set with bits OLSN and OLSP in timer output control register 1 (TOCR1) or bits OLS1P to OLS3P and OLS1N to OLS3N in timer output control register 2 (TOCR2). The output level can be set for each of the three positive phases and three negative phases of 6phase output. Complementary PWM mode should be cleared before setting or changing output levels. (e) Dead Time Setting In complementary PWM mode, PWM pulses are output with a non-overlapping relationship between the positive and negative phases. This non-overlap time is called the dead time. The non-overlap time is set in the timer dead time data register (TDDR). The value set in TDDR is used as the TCNT_3 counter start value, and creates non-overlap between TCNT_3 and TCNT_4. Complementary PWM mode should be cleared before changing the contents of TDDR. (f) Dead Time Suppressing Dead time generation is suppressed by clearing the TDER bit in the timer dead time enable register (TDER) to 0. TDER can be cleared to 0 only when 0 is written to it after reading TDER = 1. TGRA_3 and TGRC_3 should be set to 1/2 PWM carrier cycle + 1 and the timer dead time data register (TDDR) should be set to 1. By the above settings, PWM waveforms without dead time can be obtained. Figure 10.41 shows an example of operation without dead time.

The settings should be made so as to achieve the following relationship between these two registers: With dead time: TGRA_3 set value = TCDR set value + TDDR set value Without dead time: TGRA_3 set value = TCDR set value + 1 The TGRA_3 and TCDR settings are made by setting the values in buffer registers TGRC_3 and TCBR. The values set in TGRC_3 and TCBR are transferred simultaneously to TGRA_3 and TCDR in accordance with the transfer timing selected with bits MD3 to MD0 in the timer mode register (TMDR). The updated PWM cycle is reflected from the next cycle when the data update is performed at the crest, and from the current cycle when performed in the trough. Figure 10.42 illustrates the operation when the PWM cycle is updated at the crest. See the following section, Register Data Updating, for the method of updating the data in each buffer register. Counter value TGRC_3 update TGRA_3 update TCNT_3 TGRA_3 TCNT_4 Time Figure 10.42 Example of PWM Cycle Updating Rev. 2.00 May. 08, 2008 Page 483 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) (h) Register Data Updating In complementary PWM mode, the buffer register is used to update the data in a compare register. The update data can be written to the buffer register at any time. There are five PWM duty and carrier cycle registers that have buffer registers and can be updated during operation. There is a temporary register between each of these registers and its buffer register. When subcounter TCNTS is not counting, if buffer register data is updated, the temporary register value is also rewritten. Transfer is not performed from buffer registers to temporary registers when TCNTS is counting; in this case, the value written to a buffer register is transferred after TCNTS halts. The temporary register value is transferred to the compare register at the data update timing set with bits MD3 to MD0 in the timer mode register (TMDR). Figure 10.43 shows an example of data updating in complementary PWM mode. This example shows the mode in which data updating is performed at both the counter crest and trough. When rewriting buffer register data, a write to TGRD_4 must be performed at the end of the update. Data transfer from the buffer registers to the temporary registers is performed simultaneously for all five registers after the write to TGRD_4. A write to TGRD_4 must be performed after writing data to the registers to be updated, even when not updating all five registers, or when updating the TGRD_4 data. In this case, the data written to TGRD_4 should be the same as the data prior to the write operation.

This initial output is the PWM pulse non-active level, and is output from when complementary PWM mode is set with the timer mode register (TMDR) until TCNT_4 exceeds the value set in the dead time register (TDDR). Figure 10.44 shows an example of the initial output in complementary PWM mode. An example of the waveform when the initial PWM duty value is smaller than the TDDR value is shown in figure 10.45.

This non-overlap time is called the dead time. A PWM waveform is generated by output of the output level selected in the timer output control register in the event of a compare-match between a counter and data register. While TCNTS is counting, data register and temporary register values are simultaneously compared to create consecutive PWM pulses from 0 to 100%. The relative timing of on and off compare-match occurrence may vary, but the compare-match that turns off each phase takes precedence to secure the dead time and ensure that the positive phase and negative phase on times do not overlap. Figures 10.46 to 10.48 show examples of waveform generation in complementary PWM mode. The positive phase/negative phase off timing is generated by a compare-match with the solid-line counter, and the on timing by a compare-match with the dotted-line counter operating with a delay of the dead time behind the solid-line counter. In the T1 period, compare-match a that turns off the negative phase has the highest priority, and compare-matches occurring prior to a are ignored. In the T2 period, compare-match c that turns off the positive phase has the highest priority, and compare-matches occurring prior to c are ignored. In normal cases, compare-matches occur in the order a b c d (or c d a' b'), as shown in figure 10.46. If compare-matches deviate from the a b c d order, since the time for which the negative phase is off is less than twice the dead time, the figure shows the positive phase is not being turned on. If compare-matches deviate from the c d a' b' order, since the time for which the positive phase is off is less than twice the dead time, the figure shows the negative phase is not being turned on. If compare-match c occurs first following compare-match a, as shown in figure 10.47, comparematch b is ignored, and the negative phase is turned off by compare-match d. This is because turning off of the positive phase has priority due to the occurrence of compare-match c (positive phase off timing) before compare-match b (positive phase on timing) (consequently, the waveform does not change since the positive phase goes from off to off). Similarly, in the example in figure 10.48, compare-match a' with the new data in the temporary register occurs before compare-match c, but other compare-matches occurring up to c, which turns off the positive phase, are ignored. As a result, the negative phase is not turned on. Thus, in complementary PWM mode, compare-matches at turn-off timings take precedence, and turn-on timing compare-matches that occur before a turn-off timing compare-match are ignored.

Figures 10.49 to 10.53 show output examples. 100% duty output is performed when the data register value is set to H'0000. The waveform in this case has a positive phase with a 100% on-state. 0% duty output is performed when the data register value is set to the same value as TGRA_3. The waveform in this case has a positive phase with a 100% off-state. On and off compare-matches occur simultaneously, but if a turn-on compare-match and turn-off compare-match for the same phase occur simultaneously, both compare-matches are ignored and the waveform does not change. (l) Toggle Output Synchronized with PWM Cycle In complementary PWM mode, toggle output can be performed in synchronization with the PWM carrier cycle by setting the PSYE bit to 1 in the timer output control register (TOCR). An example of a toggle output waveform is shown in figure 10.54. This output is toggled by a compare-match between TCNT_3 and TGRA_3 and a compare-match between TCNT4 and H'0000. The output pin for this toggle output is the TIOC3A pin. The initial output is 1.

Figure 10.55 illustrates the operation. Use of this function enables counter clearing and restarting to be performed by means of an external signal.

Initial output suppression is applicable only when synchronous clearing occurs in the Tb interval at the trough as indicated by (10) or (11) in figure 10.56. When synchronous clearing occurs outside that interval, the initial value specified by the OLS bits in TOCR is output. Even in the Tb interval at the trough, if synchronous clearing occurs in the initial value output period (indicated by (1) in figure 10.56) immediately after the counters start operation, initial value output is not suppressed. This function can be used in both the MTU2 and MTU2S. In the MTU2, synchronous clearing generated in channels 0 to 2 in the MTU2 can cause counter clearing in complementary PWM mode; in the MTU2S, compare match or input capture flag setting in channels 0 to 2 in the MTU2 can cause counter clearing.

Figures 10.69 to 10.72 show examples of brushless DC motor drive waveforms created using TGCR. When output phase switching for a 3-phase brushless DC motor is performed by means of external signals detected with a Hall element, etc., clear the FB bit in TGCR to 0. In this case, the external signals indicating the polarity position are input to channel 0 timer input pins TIOC0A, TIOC0B, and TIOC0C (set with PFC). When an edge is detected at pin TIOC0A, TIOC0B, or TIOC0C, the output on/off state is switched automatically. When the FB bit is 1, the output on/off state is switched when the UF, VF, or WF bit in TGCR is cleared to 0 or set to 1. The drive waveforms are output from the complementary PWM mode 6-phase output pins. With this 6-phase output, in the case of on output, it is possible to use complementary PWM mode output and perform chopping output by setting the N bit or P bit to 1. When the N bit or P bit is 0, level output is selected.

When start requests using a TGRA_3 compare-match are specified, A/D conversion can be started at the crest of the TCNT_3 count. A/D converter start requests can be set by setting the TTGE bit to 1 in the timer interrupt enable register (TIER). To issue an A/D converter start request at a TCNT_4 underflow (trough), set the TTGE2 bit in TIER_4 to 1.

Transfers from a buffer register to a temporary register or a compare register can be skipped in coordination with interrupt skipping by making settings in the timer buffer transfer register (TBTER). For the linkage with buffer registers, refer to description (c), Buffer Transfer Control Linked with Interrupt Skipping, below. A/D converter start requests generated by the A/D converter start request delaying function can also be skipped in coordination with interrupt skipping by making settings in the timer A/D converter request control register (TADCR). For the linkage with the A/D converter start request delaying function, refer to section 10.4.9, A/D Converter Start Request Delaying Function. The setting of the timer interrupt skipping setting register (TITCR) must be done while the TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to clear the skipping counter. (a) Example of Interrupt Skipping Operation Setting Procedure Figure 10.73 shows an example of the interrupt skipping operation setting procedure. Figure 10.74 shows the periods during which interrupt skipping count can be changed.

Note: The setting of TITCR must be done while the TGIA_3 and TCIV_4 interrupt requests are disabled by the settings of TIER_3 and TIER_4 along with under the conditions in which TGFA_3 and TCFV_4 flag settings by compare match never occur. Before changing the skipping count, be sure to clear the T3AEN and T4VEN bits to 0 to clear the skipping counter.

Figure 10.76 shows an example of operation when buffer transfer is suppressed (BTE1 = 0 and BTE0 = 1). While this setting is valid, data is not transferred from the buffer register to the temporary register. Figure 10.77 shows an example of operation when buffer transfer is linked with interrupt skipping (BTE1 = 1 and BET0 = 0). While this setting is valid, data is not transferred from the buffer register outside the buffer transfer-enabled period. There are two types of timing in which data is transferred from the buffer register to the temporary register or to general register, depending on the buffer register modification timing after an interrupt occurrence. Note that the buffer transfer-enabled period depends on the T3AEN and T4VEN bit settings in the timer interrupt skipping set register (TITCR). Figure 10.78 shows the relationship between the T3AEN and T4VEN bit settings in TITCR and buffer transfer-enabled period. Note: This function must always be used in combination with interrupt skipping. When interrupt skipping is disabled (the T3AEN and T4VEN bits in the timer interrupt skipping set register (TITCR) are cleared to 0 or the skipping count set bits (3ACOR and 4VCOR) in TITCR are cleared to 0), make sure that buffer transfer is not linked with interrupt skipping (clear the BTE1 bit in the timer buffer transfer set register (TBTER) to 0). If buffer transfer is linked with interrupt skipping while interrupt skipping is disabled, buffer transfer is never performed.

(a) Register and counter miswrite prevention function With the exception of the buffer registers, which can be rewritten at any time, access by the CPU can be enabled or disabled for the mode registers, control registers, compare registers, and counters used in complementary PWM mode by means of the RWE bit in the timer read/write enable register (TRWER). The applicable registers are some (21 in total) of the registers in channels 3 and 4 shown in the following: * TCR_3 and TCR_4, TMDR_3 and TMDR_4, TIORH_3 and TIORH_4, TIORL_3 and TIORL_4, TIER_3 and TIER_4, TCNT_3 and TCNT_4, TGRA_3 and TGRA_4, TGRB_3 and TGRB_4, TOER, TOCR, TGCR, TCDR, and TDDR. This function enables miswriting due to CPU runaway to be prevented by disabling CPU access to the mode registers, control registers, and counters. When the applicable registers are read in the access-disabled state, undefined values are returned. Writing to these registers is ignored. (b) Halting of PWM output by external signal The 6-phase PWM output pins can be set automatically to the high-impedance state by inputting specified external signals. There are four external signal input pins. See section 12, Port Output Enable 2 (POE2), for details.

The A/D converter start request delaying function compares TCNT_4 with TADCORA_4 or TADCORB_4, and when their values match, the function issues a respective A/D converter start request (TRG4AN or TRG4BN). A/D converter start requests (TRG4AN and TRG4BN) can be skipped in coordination with interrupt skipping by making settings in the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in TADCR. * Example of Procedure for Specifying A/D Converter Start Request Delaying Function Figure 10.79 shows an example of procedure for specifying the A/D converter start request delaying function. [1] Set the cycle in the timer A/D converter start request cycle buffer register (TADCOBRA_4 or TADCOBRB_4) and timer A/D converter start request cycle register (TADCORA_4 or TADCORB_4). (The same initial value must be specified in the cycle buffer register and cycle register.) [2] Use bits BF1 and BF2 in the timer A/D converter start request control register (TADCR) to specify the timing of transfer from the timer A/D converter start request cycle buffer register to A/D converter start request cycle register. * Specify whether to link with interrupt skipping through bits ITA3AE, ITA4VE, ITB3AE, and ITB4VE. * Use bits TU4AE, DT4AE, UT4BE, and DT4BE to enable A/D conversion start requests (TRG4AN or TRG4BN). Notes: 1. Perform TADCR setting while TCNT_4 is stopped. 2. Do not set BF1 to 1 when complementary PWM mode is not selected. 3. Do not set ITA3AE, ITA4VE, ITB3AE, ITB4VE, DT4AE, or DT4BE to 1 when complementary PWM mode is not selected.

Data is transferred from the buffer registers to the respective cycle set registers at the timing selected with the BF1 and BF0 bits in the timer A/D converter start request control register (TADCR_4). * A/D Converter Start Request Delaying Function Linked with Interrupt Skipping A/D converter start requests (TRG4AN and TRG4BN) can be issued in coordination with interrupt skipping by making settings in the ITA3AE, ITA4VE, ITB3AE, and ITB4VE bits in the timer A/D converter start request control register (TADCR). Figure 10.81 shows an example of A/D converter start request signal (TRG4AN) operation when TRG4AN output is enabled during TCNT_4 up-counting and down-counting and A/D converter start requests are linked with interrupt skipping. Figure 10.82 shows another example of A/D converter start request signal (TRG4AN) operation when TRG4AN output is enabled during TCNT_4 up-counting and A/D converter start requests are linked with interrupt skipping.

(a) Example of MTU2-MTU2S Synchronous Counter Start Setting Procedure Figure 10.83 shows an example of synchronous counter start setting procedure. [1] Use TSTR registers in the MTU2 and MTU2S and halt the counters used for synchronous start operation. [2] Specify necessary operation with appropriate registers such as TCR and TMDR. Stop count operation [1] [3] In TCSYSTR in the MTU2, set the bits corresponding to the counters to be started synchronously to 1. The TSTRs are automatically set appropriately and the counters start synchronously. Notes: 1. Even if a bit in TCSYSTR corresponding to an operating counter is cleared to 0, the counter will not stop. To stop the counter, clear the corresponding bit in TSTR to 0 directly. 2. To start channels 3 and 4 in reset-synchronized PWM mode or complementary PWM mode, make appropriate settings in TCYSTR according to the TSTR setting for the respective mode.

Each interrupt source has its own status flag and enable/disabled bit, allowing the generation of interrupt request signals to be enabled or disabled individually. When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The interrupt request is cleared by clearing the status flag to 0. Relative channel priorities can be changed by the interrupt controller, however the priority order within a channel is fixed. For details, see section 6, Interrupt Controller (INTC). Table 10.57 lists the MTU2 interrupt sources.

The interrupt request is cleared by clearing the TGF flag to 0. The MTU2 has 21 input capture/compare match interrupts, six for channel 0, four each for channels 3 and 4, two each for channels 1 and 2, and three for channel 5. The TGFE_0 and TGFF_0 flags in channel 0 are not set by the occurrence of an input capture. (2) Overflow Interrupt An interrupt is requested if the TCIEV bit in TIER is set to 1 when the TCFV flag in TSR is set to 1 by the occurrence of TCNT overflow on a channel. The interrupt request is cleared by clearing the TCFV flag to 0. The MTU2 has five overflow interrupts, one for each channel. (3) Underflow Interrupt An interrupt is requested if the TCIEU bit in TIER is set to 1 when the TCFU flag in TSR is set to 1 by the occurrence of TCNT underflow on a channel. The interrupt request is cleared by clearing the TCFU flag to 0. The MTU2 has two underflow interrupts, one each for channels 1 and 2. 10.5.2 DMAC Activation The DMAC can be activated by the TGRA input capture/compare match interrupt in each channel. For details, see section 9, Direct Memory Access Controller (DMAC). In the MTU2, a total of five TGRA input capture/compare match interrupts can be used as DMAC activation sources, one each for channels 0 to 4. Rev. 2.00 May. 08, 2008 Page 535 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) 10.5.3 A/D Converter Activation The A/D converter can be activated by one of the following three methods in the MTU2. Table 10.58 shows the relationship between interrupt sources and A/D converter start request signals. (1) A/D Converter Activation by TGRA Input Capture/Compare Match or at TCNT_4 Trough in Complementary PWM Mode The A/D converter can be activated by the occurrence of a TGRA input capture/compare match in each channel. In addition, if complementary PWM operation is performed while the TTGE2 bit in TIER_4 is set to 1, the A/D converter can be activated at the trough of TCNT_4 count (TCNT_4 = H'0000). A/D converter start request signal TRGAN is issued to the A/D converter under either one of the following conditions. * When the TGFA flag in TSR is set to 1 by the occurrence of a TGRA input capture/compare match on a particular channel while the TTGE bit in TIER is set to 1 * When the TCNT_4 count reaches the trough (TCNT_4 = H'0000) during complementary PWM operation while the TTGE2 bit in TIER_4 is set to 1 When either condition is satisfied, if A/D converter start signal TRGAN from the MTU2 is selected as the trigger in the A/D converter, A/D conversion will start. (2) A/D Converter Activation by Compare Match between TCNT_0 and TGRE_0 The A/D converter can be activated by generating A/D converter start request signal TRG0N when a compare match occurs between TCNT_0 and TGRE_0 in channel 0. When the TGFE flag in TSR2_0 is set to 1 by the occurrence of a compare match between TCNT_0 and TGRE_0 in channel 0 while the TTGE2 bit in TIER2_0 is set to 1, A/D converter start request TGR0N is issued to the A/D converter. If A/D converter start signal TGR0N from the MTU2 is selected as the trigger in the A/D converter, A/D conversion will start. Rev. 2.00 May. 08, 2008 Page 536 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) (3) A/D Converter Activation by A/D Converter Start Request Delaying Function The A/D converter can be activated by generating A/D converter start request signal TRG4AN or TRG4BN when the TCNT_4 count matches the TADCORA or TADCORB value if the TAD4AE or TAD4BE bit in the A/D converter start request control register (TADCR) is set to 1. For details, refer to section 10.4.9, A/D Converter Start Request Delaying Function. A/D conversion will start if A/D converter start signal TRG4AN from the MTU2 is selected as the trigger in the A/D converter when TRG4AN is generated or if TRG4BN from the MTU2 is selected as the trigger in the A/D converter when TRG4BN is generated.

The initial setting is for MTU2 operation to be halted. Register access is enabled by clearing module standby mode. For details, refer to section 23, Power-Down Modes. 10.7.2 Input Clock Restrictions The input clock pulse width must be at least 1.5 states in the case of single-edge detection, and at least 2.5 states in the case of both-edge detection. The MTU2 will not operate properly at narrower pulse widths. In phase counting mode, the phase difference and overlap between the two input clocks must be at least 1.5 states, and the pulse width must be at least 2.5 states.

At this point, if there is match with TGRA_1 and the TCNT_1 value, a compare signal is issued. Furthermore, when the TCNT_1 count clock is selected as the input capture source of channel 0, TGRA_0 to D_0 carry out the input capture operation. In addition, when the compare match/input capture is selected as the input capture source of TGRB_1, TGRB_1 carries out input capture operation. The timing is shown in figure 10.129. For cascade connections, be sure to synchronize settings for channels 1 and 2 when setting TCNT clearing.

In complementary PWM mode, channel 3 and channel 4 buffers operate in accordance with bit settings BFA and BFB of TMDR_3. When TMDR_3's BFA bit is set to 1, TGRC_3 functions as a buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for TGRA_4, and TCBR functions as the TCDR's buffer register.

The TIOC4C pin will be unable to produce its waveform output if the BFA bit of TMDR_4 is set to 1. In reset sync PWM mode, the channel 3 and channel 4 buffers operate in accordance with the BFA and BFB bit settings of TMDR_3. For example, if the BFA bit of TMDR_3 is set to 1, TGRC_3 functions as the buffer register for TGRA_3. At the same time, TGRC_4 functions as the buffer register for TGRA_4. The TGFC bit and TGFD bit of TSR_3 and TSR_4 are not set when TGRC_3 and TGRD_3 are operating as buffer registers. Figure 10.131 shows an example of operations for TGR_3, TGR_4, TIOC3, and TIOC4, with TMDR_3's BFA and BFB bits set to 1, and TMDR_4's BFA and BFB bits set to 0.

At this point, TCNT_4's count clock source and count edge obey the TCR_3 setting. In reset synchronous PWM mode, with cycle register TGRA_3's set value at H'FFFF, when specifying TGR3A compare-match for the counter clear source, TCNT_3 and TCNT_4 count up to H'FFFF, then a compare-match occurs with TGRA_3, and TCNT_3 and TCNT_4 are both cleared. At this point, TSR's overflow flag TCFV bit is not set. Figure 10.132 shows a TCFV bit operation example in reset synchronous PWM mode with a set value for cycle register TGRA_3 of H'FFFF, when a TGRA_3 compare-match has been specified without synchronous setting for the counter clear source.

When making a transition from normal operation to reset-synchronized PWM mode, write H'11 to registers TIORH_3, TIORL_3, TIORH_4, and TIORL_4 to initialize the output pins to low level output, then set an initial register value of H'00 before making the mode transition. When making a transition from PWM mode 1 to reset-synchronized PWM mode, first switch to normal operation, then initialize the output pins to low level output and set an initial register value of H'00 before making the transition to reset-synchronized PWM mode. Rev. 2.00 May. 08, 2008 Page 564 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) 10.7.20 Output Level in Complementary PWM Mode and Reset-Synchronized PWM Mode When channels 3 and 4 are in complementary PWM mode or reset-synchronized PWM mode, the PWM waveform output level is set with the OLSP and OLSN bits in the timer output control register (TOCR). In the case of complementary PWM mode or reset-synchronized PWM mode, TIOR should be set to H'00. 10.7.21 Interrupts in Module Standby Mode If module standby mode is entered when an interrupt has been requested, it will not be possible to clear the CPU interrupt source or the DMAC activation source. Interrupts should therefore be disabled before entering module standby mode. 10.7.22 Simultaneous Capture of TCNT_1 and TCNT_2 in Cascade Connection When timer counters 1 and 2 (TCNT_1 and TCNT_2) are operated as a 32-bit counter in cascade connection, the cascade counter value cannot be captured successfully even if input-capture input is simultaneously done to TIOC1A and TIOC2A or to TIOC1B and TIOC2B. This is because the input timing of TIOC1A and TIOC2A or of TIOC1B and TIOC2B may not be the same when external input-capture signals to be input into TCNT_1 and TCNT_2 are taken in synchronization with the internal clock. For example, TCNT_1 (the counter for upper 16 bits) does not capture the count-up value by overflow from TCNT_2 (the counter for lower 16 bits) but captures the count value before the count-up. In this case, the values of TCNT_1 = H'FFF1 and TCNT_2 = H'0000 should be transferred to TGRA_1 and TGRA_2 or to TGRB_1 and TGRB_2, but the values of TCNT_1 = H'FFF0 and TCNT_2 = H'0000 are erroneously transferred. The MTU2 additionally supports the function that can capture TCNT_1 and TCNT_2 simultaneously via a single input capture input. This function allows 32-bit counter fetches without TCNT_1 and TCNT_2 capture timing deviation. For details, see section 10.3.8, Timer Input Capture Control Register (TICCR). Rev. 2.00 May. 08, 2008 Page 565 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) 10.8 10.8.1 MTU2 Output Pin Initialization Operating Modes The MTU2 has the following six operating modes. Waveform output is possible in all of these modes. * Normal mode (channels 0 to 4) * PWM mode 1 (channels 0 to 4) * PWM mode 2 (channels 0 to 2) * Phase counting modes 1 to 4 (channels 1 and 2) * Complementary PWM mode (channels 3 and 4) * Reset-synchronized PWM mode (channels 3 and 4) The MTU2 output pin initialization method for each of these modes is described in this section. 10.8.2 Reset Start Operation The MTU2 output pins (TIOC*) are initialized low by a reset and in standby mode. Since MTU2 pin function selection is performed by the pin function controller (PFC), when the PFC is set, the MTU2 pin states at that point are output to the ports. When MTU2 output is selected by the PFC immediately after a reset, the MTU2 output initial level, low, is output directly at the port. When the active level is low, the system will operate at this point, and therefore the PFC setting should be made after initialization of the MTU2 output pins is completed. Note: Channel number and port notation are substituted for *. Rev. 2.00 May. 08, 2008 Page 566 of 1200 REJ09B0344-0200 Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) 10.8.3 Operation in Case of Re-Setting Due to Error During Operation, etc. If an error occurs during MTU2 operation, MTU2 output should be cut by the system. Cutoff is performed by switching the pin output to port output with the PFC and outputting the inverse of the active level. For large-current pins, output can also be cut by hardware, using port output enable (POE). The pin initialization procedures for re-setting due to an error during operation, etc., and the procedures for restarting in a different mode after re-setting, are shown below. The MTU2 has six operating modes, as stated above. There are thus 36 mode transition combinations, but some transitions are not available with certain channel and mode combinations. Possible mode transition combinations are shown in table 10.59.

If initialization is required, carry it out in normal mode, then switch to PWM mode 1. * In PWM mode 2, since a waveform is not output to the cycle register pin, setting TIOR will not initialize the pins. If initialization is required, carry it out in normal mode, then switch to PWM mode 2. * In normal mode or PWM mode 2, if TGRC and TGRD operate as buffer registers, setting TIOR will not initialize the buffer register pins. If initialization is required, clear buffer mode, carry out initialization, then set buffer mode again. * In PWM mode 1, if either TGRC or TGRD operates as a buffer register, setting TIOR will not initialize the TGRC pin. To initialize the TGRC pin, clear buffer mode, carry out initialization, then set buffer mode again. * When making a transition to a mode (CPWM, RPWM) in which the pin output level is selected by the timer output control register (TOCR) setting, switch to normal mode and perform initialization with TIOR, then restore TIOR to its initial value, and temporarily disable channel 3 and 4 output with the timer output master enable register (TOER). Then operate the unit in accordance with the mode setting procedure (TOCR setting, TMDR setting, TOER setting). Note: Channel number is substituted for * indicated in this article. Pin initialization procedures are described below for the numbered combinations in table 10.59. The active level is assumed to be low.

The MTU2S includes channels 3 to 5 of the MTU2. For details, refer to section 10, Multi-Function Timer Pulse Unit 2 (MTU2). The MTU2S operates on M clock (MTU clock) while the MTU2 operates on P clock (peripheral clock) thus the term P in the MTU2 corresponds to M in the MTU2S. To distinguish from the MTU2, "S" is added to the end of the MTU2S input/output pin and register names. For example, TIOC3A is called TIOC3AS and TGRA_3 is called TGRA_3S in this section. The MTU2S can operate at 80 MHz max. for complementary PWM output functions or at 40 MHz max. for the other functions.

(In the case of TOCS = 0 in timer output control register 1 (TOCR1) in the MTU2, low level when the output level select P (OLSP) bit is 0, or high level when the OLSP bit is 1. In the case of TOCS = 1, low level when the OLS3N, OLS3P, OLS2N, OLS2P, OLS1N, and OLS1P bits are 0 in TOCR2, or high level when these bits are 1.) This active level comparison is done when the MTU2 output function or general output function is selected in the pin function controller. If another function is selected, the output level is not checked. Pin combinations for output comparison and highimpedance control can be selected by POE2 registers. PB21/TIOC3BS and PB20/TIOC3DS Output The high-current pins for the MTU2S are placed in high-impedance state when the pins PB12/TIOC4AS and PB10/TIOC4CS simultaneously output an active level for one or PB13/TIOC4BS and PB11/TIOC4DS more cycles of the peripheral clock (P). (In the case of TOCS = 0 in timer output control register 1S (TOCR1S) in the MTU2S, low level when the output level select P (OLSP) bit is 0, or high level when the OLSP bit is 1. In the case of TOCS = 1, low level when the OLS3N, OLS3P, OLS2N, OLS2P, OLS1N, and OLS1P bits are 0 in TOCR2S, or high level when these bits are 1.)

Note however, that these high-current and MTU2 pins enter high-impedance state only when general input/output function, MTU2 function, or MTU2S function is selected for these pins. (1) Falling Edge Detection When a change from a high to low level is input to the POE0, POE1, POE3, POE4, POE7, and POE8 pins, the high-current pins and the pins for channel 0 of the MTU2 are placed in highimpedance state.

However, note that when low-level sampling is selected by bits 7 to 0 in ICSR1 to ICSR3, just writing 0 to a flag is ignored (the flag is not cleared); flags can be cleared by writing 0 to it only after a high level is input to one of the POE0, POE1, POE3, POE4, POE7, and POE8 pins and is sampled. High-current pins that have entered high-impedance state due to output-level detection can be released either by returning them to their initial state with a power-on reset, or by clearing the flag in bit 15 (OCF1 and OCF2) in OCSR1 and OCSR2. However, note that just writing 0 to a flag is ignored (the flag is not cleared); flags can be cleared only after an inactive level is output from the high-current pins. Inactive-level outputs can be achieved by setting the MTU2 and MTU2S internal registers.

If a power-on reset is issued by the WDT during high-impedance processing by the port output enable (POE) signal, the I/O port pins are placed in output state for a time period of one cycle of the peripheral clock, P, until the pin functions switch to general inputs. If a power-on reset is issued by the WDT during high-impedance processing by MTU2 or MTU2S short detection, the I/O port pins are placed in the same status as described above. Figure 12.5 shows the I/O port pin status when a power-on reset is issued by the WDT during high-impedance processing by the POE input while the timer output is selected.

When the values in CMCNT and CMCOR match, CMCNT is cleared to H'0000 and the CMF flag in CMCSR is set to 1.

When both the interrupt request flag (CMF) and the interrupt enable bit (CMIE) are set to 1, the corresponding interrupt request is output. When the interrupt is used to activate a CPU interrupt, the priority of channels can be changed by the interrupt controller settings. For details, see section 6, Interrupt Controller (INTC). Clear the CMF bit to 0 by the user exception handling routine. If this operation is not carried out, another interrupt will be generated. The direct memory access controller (DMAC) can be set to be activated when a compare match interrupt is requested. In this case, an interrupt is not issued to the CPU. If the setting to activate the DMAC has not been made, an interrupt request is sent to the CPU. The CMF bit is automatically cleared to 0 when data is transferred by the DMAC. 13.4.2 Timing of Compare Match Flag Setting When CMCOR and CMCNT match, a compare match signal is generated at the last state in which the values match (the timing when the CMCNT value is updated to H'0000) and the CMF bit in CMCSR is set to 1. That is, after a match between CMCOR and CMCNT, the compare match signal is not generated until the next CMCNT counter clock input. Figure 13.4 shows the timing of CMF bit setting.

The WDT can simultaneously generate an internal reset signal for the entire LSI. The WDT is a single channel timer that counts up the clock oscillation settling period when the system leaves software standby mode or the temporary standby periods that occur when the clock frequency is changed. It can also be used as a general watchdog timer or interval timer. 14.1 Features * Can be used to ensure the clock oscillation settling time The WDT is used in leaving software standby mode or the temporary standby periods that occur when the clock frequency is changed. * Can switch between watchdog timer mode and interval timer mode. * Outputs WDTOVF signal in watchdog timer mode When the counter overflows in watchdog timer mode, the WDTOVF signal is output externally. It is possible to select whether to reset the LSI internally when this happens. Either the power-on reset or manual reset signal can be selected as the internal reset type. * Interrupt generation in interval timer mode An interval timer interrupt is generated when the counter overflows. * Choice of eight counter input clocks Eight clocks (P x 1 to P x 1/16384) that are obtained by dividing the peripheral clock can be selected.

The procedures for reading or writing to these registers are given below. (1) Writing to WTCNT and WTCSR These registers must be written by a word transfer instruction. They cannot be written by a byte or longword transfer instruction. When writing to WTCNT, set the upper byte to H'5A and transfer the lower byte as the write data, as shown in figure 14.2. When writing to WTCSR, set the upper byte to H'A5 and transfer the lower byte as the write data. This transfer procedure writes the lower byte data to WTCNT or WTCSR. WTCNT write Address: H'FFFE0002 15 H'5A 8 7 Write data 0 WTCSR write Address: H'FFFE0000 15 H'A5 8 7 Write data 0 Figure 14.2 Writing to WTCNT and WTCSR Rev. 2.00 May. 08, 2008 Page 656 of 1200 REJ09B0344-0200 Section 14 Watchdog Timer (WDT) (2) Writing to WRCSR WRCSR must be written by a word access to address H'FFFE0004. It cannot be written by byte transfer or longword transfer instructions. Procedures for writing 0 to WOVF (bit 7) and for writing to RSTE (bit 6) and RSTS (bit 5) are different, as shown in figure 14.3. To write 0 to the WOVF bit, the write data must be H'A5 in the upper byte and H'00 in the lower byte. This clears the WOVF bit to 0. The RSTE and RSTS bits are not affected. To write to the RSTE and RSTS bits, the upper byte must be H'5A and the lower byte must be the write data. The values of bits 6 and 5 of the lower byte are transferred to the RSTE and RSTS bits, respectively. The WOVF bit is not affected. Writing 0 to the WOVF bit 15 Address: H'FFFE0004 H'A5 8 7 H'00 0 Writing to the RSTE and RSTS bits Address: H'FFFE0004 15 H'5A 8 7 Write data 0 Figure 14.3 Writing to WRCSR (3) Reading from WTCNT, WTCSR, and WRCSR WTCNT, WTCSR, and WRCSR are read in a method similar to other registers. WTCSR is allocated to address H'FFFE0000, WTCNT to address H'FFFE0002, and WRCSR to address H'FFFE0004. Byte transfer instructions must be used for reading from these registers.

The procedure is described below. (The WDT does not operate when resets are used for canceling, so keep the RES or MRES pin low until clock oscillation settles.) 1. Before making a transition to software standby mode, always clear the TME bit in WTCSR to 0. When the TME bit is 1, an erroneous reset or interval timer interrupt may be generated when the count overflows. 2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the counter in WTCNT. These values should ensure that the time till count overflow is longer than the clock oscillation settling time. 3. After setting the STBY bit of the standby control register (STBCR: see section 23, PowerDown Modes) to 1, the execution of a SLEEP instruction puts the system in software standby mode and clock operation then stops. 4. The WDT starts counting by detecting the edge change of the NMI signal. 5. When the WDT count overflows, the CPG starts supplying the clock and this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens.

When changing the frequency only by switching the divider, do not use the WDT. 1. Before changing the frequency, always clear the TME bit in WTCSR to 0. When the TME bit is 1, an erroneous reset or interval timer interrupt may be generated when the count overflows. 2. Set the type of count clock used in the CKS[2:0] bits in WTCSR and the initial value of the counter in WTCNT. These values should ensure that the time till count overflow is longer than the clock oscillation settling time. 3. When the frequency control register (FRQCR) is written to, this LSI stops temporarily. The WDT starts counting. 4. When the WDT count overflows, the CPG resumes supplying the clock and this LSI resumes operation. The WOVF flag in WRCSR is not set when this happens. 5. The counter stops at the value of H'00. 6. Before changing WTCNT after execution of the frequency change instruction, always confirm that the value of WTCNT is H'00 by reading from WTCNT.

Set the WT/IT bit in WTCSR to 1, the type of count clock in the CKS[2:0] bits in WTCSR, whether this LSI is to be reset internally or not in the RSTE bit in WRCSR, the reset type if it is generated in the RSTS bit in WRCSR, and the initial value of the counter in WTCNT. 2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode. 3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent the counter from overflowing. 4. When the counter overflows, the WDT sets the WOVF flag in WRCSR to 1, and the WDTOVF signal is output externally (figure 14.4). The WDTOVF signal can be used to reset the system. The WDTOVF signal is output for 64 x P clock cycles. 5. If the RSTE bit in WRCSR is set to 1, a signal to reset the inside of this LSI can be generated simultaneously with the WDTOVF signal. Either power-on reset or manual reset can be selected for this interrupt by the RSTS bit in WRCSR. The internal reset signal is output for 128 x P clock cycles. 6. When a WDT overflow reset is generated simultaneously with a reset input on the RES pin, the RES pin reset takes priority, and the WOVF bit in WRCSR is cleared to 0.

This enables interrupts to be generated at set periods. 1. Clear the WT/IT bit in WTCSR to 0, set the type of count clock in the CKS[2:0] bits in WTCSR, and set the initial value of the counter in WTCNT. 2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode. 3. When the counter overflows, the WDT sets the IOVF bit in WTCSR to 1 and an interval timer interrupt request is sent to the INTC. The counter then resumes counting.

The shortest such time period is thus one cycle of the peripheral clock, P, while the longest is the result of frequency division according to the value in the CKS[2:0] bits. The timing of subsequent incrementation is in accord with the selected frequency division ratio. Accordingly, this time difference is referred to as timer variation. This also applies to the timing of the first incrementation after WTCNT has been written to during timer operation. 14.5.2 Prohibition against Setting H'FF to WTCNT When the value in WTCNT reaches H'FF, the WDT assumes that an overflow has occurred. Accordingly, when H'FF is set in WTCNT, an interval timer interrupt or WDT reset will occur immediately, regardless of the current clock selection by the CKS[2:0] bits. 14.5.3 System Reset by WDTOVF Signal If the WDTOVF signal is input to the RES pin of this LSI, this LSI cannot be initialized correctly. Avoid input of the WDTOVF signal to the RES pin of this LSI through glue logic circuits. To reset the entire system with the WDTOVF signal, use the circuit shown in figure 14.6. Reset input RES Reset signal to entire system WDTOVF Figure 14.6 Example of System Reset Circuit Using WDTOVF Signal Rev. 2.00 May. 08, 2008 Page 663 of 1200 REJ09B0344-0200 Section 14 Watchdog Timer (WDT) 14.5.4 Manual Reset in Watchdog Timer Mode When a manual reset occurs in watchdog timer mode, the bus cycle is continued. If a manual reset occurs while the bus is released or during DMAC burst transfer, manual reset exception handling will be pended until the CPU acquires the bus mastership. However, if the duration from generation of the manual reset to the bus cycle end is equal to or longer than the duration of the internal manual reset activated, the occurrence of the internal manual reset source is ignored instead of being pended, and the manual reset exception handling is not executed. Rev. 2.00 May. 08, 2008 Page 664 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) Section 15 Serial Communication Interface with FIFO (SCIF) This LSI has a four-channel serial communication interface with FIFO (SCIF) that supports both asynchronous and clocked synchronous serial communication. It also has 16-stage FIFO registers for both transmission and reception independently for each channel that enable this LSI to perform efficient high-speed continuous communication. 15.1 Features * Asynchronous serial communication: Serial data communication is performed by start-stop in character units. The SCIF can communicate with a universal asynchronous receiver/transmitter (UART), an asynchronous communication interface adapter (ACIA), or any other communications chip that employs a standard asynchronous serial system. There are eight selectable serial data communication formats. Data length: 7 or 8 bits Stop bit length: 1 or 2 bits Parity: Even, odd, or none Receive error detection: Parity, framing, and overrun errors Break detection: Break is detected when a framing error is followed by at least one frame at the space 0 level (low level). It is also detected by reading the RXD level directly from the serial port register when a framing error occurs. * Clocked synchronous serial communication: Serial data communication is synchronized with a clock signal. The SCIF can communicate with other chips having a clocked synchronous communication function. There is one serial data communication format. Data length: 8 bits Receive error detection: Overrun errors * Full duplex communication: The transmitting and receiving sections are independent, so the SCIF can transmit and receive simultaneously. Both sections use 16-stage FIFO buffering, so high-speed continuous data transfer is possible in both the transmit and receive directions. * On-chip baud rate generator with selectable bit rates * Internal or external transmit/receive clock source: From either baud rate generator (internal) or SCK pin (external) Rev. 2.00 May. 08, 2008 Page 665 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) * Four types of interrupts: Transmit-FIFO-data-empty interrupt, break interrupt, receive-FIFOdata-full interrupt, and receive-error interrupts are requested independently. * When the SCIF is not in use, it can be stopped by halting the clock supplied to it, saving power. * The quantity of data in the transmit and receive FIFO data registers and the number of receive errors of the receive data in the receive FIFO data register can be ascertained. * A time-out error (DR) can be detected when receiving in asynchronous mode.

Data input at the RXD pin is loaded into SCRSR in the order received, LSB (bit 0) first, converting the data to parallel form. When one byte has been received, it is automatically transferred to the receive FIFO data register (SCFRDR). The CPU cannot read or write to SCRSR directly. Bit: 7 6 5 4 3 2 1 0 Initial value: R/W: - - - - - - - - 15.3.2 Receive FIFO Data Register (SCFRDR) SCFRDR is a register that stores serial receive data. The SCIF completes the reception of one byte of serial data by moving the received data from the receive shift register (SCRSR) into SCFRDR for storage. Continuous reception is possible until 16 bytes are stored. The CPU can read but not write to SCFRDR. If data is read when there is no receive data in the SCFRDR, the value is undefined. When SCFRDR is full of receive data, subsequent serial data is lost. SCFRDR is initialized to an undefined value by a power-on reset.

The SCIF loads transmit data from the transmit FIFO data register (SCFTDR) into SCTSR, then transmits the data serially from the TXD pin, LSB (bit 0) first. After transmitting one data byte, the SCIF automatically loads the next transmit data from SCFTDR into SCTSR and starts transmitting again. The CPU cannot read or write to SCTSR directly. Bit: 7 6 5 4 3 2 1 0 Initial value: R/W: - - - - - - - - 15.3.4 Transmit FIFO Data Register (SCFTDR) SCFTDR is a 16-byte FIFO register that stores data for serial transmission. When the SCIF detects that the transmit shift register (SCTSR) is empty, it moves transmit data written in the SCFTDR into SCTSR and starts serial transmission. Continuous serial transmission is performed until there is no transmit data left in SCFTDR. The CPU can write to SCFTDR at all times. When SCFTDR is full of transmit data (16 bytes), no more data can be written. If writing of new data is attempted, the data is ignored.

The O/E setting is used only in asynchronous mode and only when the parity enable bit (PE) is set to 1 to enable parity addition and checking.

Receive data is checked to see if it has an even number of 1s in the received character and parity bit combined. 2. If odd parity is selected, the parity bit is added to transmit data to make an odd number of 1s in the transmitted character and parity bit combined.

The SCIF has a 16-stage FIFO buffer for both transmission and receptions, reducing the overhead of the CPU, and enabling continuous high-speed communication. The transmission format is selected in the serial mode register (SCSMR), as shown in table 15.9. The SCIF clock source is selected by the combination of the CKE1 and CKE0 bits in the serial control register (SCSCR), as shown in table 15.10. (1) Asynchronous Mode * Data length is selectable: 7 or 8 bits * Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding selections constitutes the communication format and character length. * In receiving, it is possible to detect framing errors, parity errors, receive FIFO data full, overrun errors, receive data ready, and breaks. * The number of stored data bytes is indicated for both the transmit and receive FIFO registers. * An internal or external clock can be selected as the SCIF clock source. When an internal clock is selected, the SCIF operates using the clock of on-chip baud rate generator. When an external clock is selected, the external clock input must have a frequency 16 times the bit rate. (The on-chip baud rate generator is not used.) (2) Clocked Synchronous Mode * The transmission/reception format has a fixed 8-bit data length. * In receiving, it is possible to detect overrun errors (ORER). * An internal or external clock can be selected as the SCIF clock source. When an internal clock is selected, the SCIF operates using the clock of the on-chip baud rate generator, and outputs this clock to external devices as the synchronous clock. When an external clock is selected, the SCIF operates on the input synchronous clock not using the on-chip baud rate generator.

Serial communication is synchronized one character at a time. The transmitting and receiving sections of the SCIF are independent, so full duplex communication is possible. The transmitter and receiver are 16-byte FIFO buffered, so data can be written and read while transmitting and receiving are in progress, enabling continuous transmitting and receiving. Figure 15.2 shows the general format of asynchronous serial communication. In asynchronous serial communication, the communication line is normally held in the mark (high) state. The SCIF monitors the line and starts serial communication when the line goes to the space (low) state, indicating a start bit. One serial character consists of a start bit (low), data (LSB first), parity bit (high or low), and stop bit (high), in that order. When receiving in asynchronous mode, the SCIF synchronizes at the falling edge of the start bit. The SCIF samples each data bit on the eighth pulse of a clock with a frequency 16 times* the bit rate. Receive data is latched at the center of each bit. Idle state (mark state) 1 Serial data 0 Start bit 1 bit (LSB) D0 D1 D2 D3 D4 D5 D6 (MSB) D7 0/1 Parity bit 1 bit or none 1 Stop bit 1 1 Transmit/receive data 7 or 8 bits 1 or 2 bits One unit of transfer data (character or frame) Figure 15.2 Example of Data Format in Asynchronous Communication (8-Bit Data with Parity and Two Stop Bits) Note: * This is an example when ABCS = 0 in SCSEMR. When ABCS = 1, a frequency of 8 times the bit rate becomes the basic clock, and receive data is sampled at the fourth rising edge of the basic clock.

The format is selected by settings in the serial mode register (SCSMR).

The clock source is selected by the C/A bit in the serial mode register (SCSMR) and bits CKE[1:0] in the serial control register (SCSCR). For clock source selection, refer to table 15.10, SCSMR and SCSCR Settings and SCIF Clock Source Selection. When an external clock is input at the SCK pin, it must have a frequency equal to 16 times the desired bit rate. When the SCIF operates on an internal clock, it can output a clock signal on the SCK pin. The frequency of this output clock is 16 times the desired bit rate.

When changing the operating mode or the communication format, always clear the TE and RE bits to 0 before following the procedure given below. Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing TE and RE to 0, however, does not initialize the serial status register (SCFSR), transmit FIFO data register (SCFTDR), or receive FIFO data register (SCFRDR), which retain their previous contents. Clear TE to 0 after all transmit data has been transmitted and the TEND flag in the SCFSR is set. The TE bit can be cleared to 0 during transmission, but the transmit data goes to the Mark state after the bit is cleared to 0. Set the TFRST bit in SCFCR to 1 and reset SCFTDR before TE is set again to start transmission. When an external clock is used, the clock should not be stopped during initialization or subsequent operation. SCIF operation becomes unreliable if the clock is stopped. Rev. 2.00 May. 08, 2008 Page 703 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) Figure 15.3 shows a sample flowchart for initializing the SCIF. Start of initialization Clear TE and RE bits in SCSCR to 0 [1] Set the clock selection in SCSCR. Be sure to clear bits TIE, RIE, TE, and RE to 0. [2] Set the data transfer format in SCSMR.

Setting the TE and RE bits enables the TxD and RxD pins to be used. When transmitting, the SCIF will go to the mark state; when receiving, it will go to the idle state, waiting for a start bit. Set TFRST and RFRST bits in SCFCR to 1 After reading ER, DR, and BRK flags in SCFSR, and each flag in SCLSR, write 0 to clear them Set CKE1 and CKE0 in SCSCR (leaving TIE, RIE, TE, and RE bits cleared to 0) Set data transfer format in SCSMR Set value in SCBRR Set ABCS in SCSEMR Set RTRG[1:0] and TTRG[1:0] in SCFCR, and clear TFRST and RFRST [2] [3] Set TE and RE bits in SCSCR to 1, and set TIE, RIE, and REIE bits End of initialization [4] Figure 15.3 Sample Flowchart for SCIF Initialization Rev. 2.00 May. 08, 2008 Page 704 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) * Transmitting Serial Data (Asynchronous Mode) Figure 15.4 shows a sample flowchart for serial transmission. Use the following procedure for serial data transmission after enabling the SCIF for transmission. Start of transmission [1] SCIF status check and transmit data write: Read SCFSR and check that the TDFE flag is set to 1, then write transmit data to SCFTDR, and read 1 from the TDFE and TEND flags, then clear to 0. The quantity of transmit data that can be written is 16 - (transmit trigger set number). [2] Serial transmission continuation procedure: To continue serial transmission, read 1 from the TDFE flag to confirm that writing is possible, then write data to SCFTDR, and then clear the TDFE flag to 0. [3] Break output during serial transmission: To output a break in serial transmission, clear the SPB2DT bit to 0 and set the SPB2IO bit to 1 in SCSPTR, then clear the TE bit in SCSCR to 0.

[3] Clear TE bit in SCSCR to 0 End of transmission Figure 15.4 Sample Flowchart for Transmitting Serial Data Rev. 2.00 May. 08, 2008 Page 705 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) In serial transmission, the SCIF operates as described below. 1. When data is written into the transmit FIFO data register (SCFTDR), the SCIF transfers the data from SCFTDR to the transmit shift register (SCTSR) and starts transmitting. Confirm that the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of data bytes that can be written is (16 - transmit trigger setting). 2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive transmit operations are performed until there is no transmit data left in SCFTDR. When the number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register (SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is generated. The serial transmit data is sent from the TXD pin in the following order. A. Start bit: One-bit 0 is output. B. Transmit data: 8-bit or 7-bit data is output in LSB-first order. C. Parity bit: One parity bit (even or odd parity) is output. (A format in which a parity bit is not output can also be selected.) D. Stop bit(s): One or two 1 bits (stop bits) are output. E. Mark state: 1 is output continuously until the start bit that starts the next transmission is sent. 3. The SCIF checks the SCFTDR transmit data at the timing for sending the stop bit. If data is present, the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial transmission of the next frame is started.

Use the following procedure for serial data reception after enabling the SCIF for reception. [1] Receive error handling and break detection: Read the DR, ER, and BRK flags in SCFSR, and the ORER flag in SCLSR, to identify any error, perform the appropriate error handling, then clear the DR, ER, BRK, and ORER flags to 0. In the case of a framing error, a break can also be detected by reading the value of the RxD pin. [2] SCIF status check and receive data read: Read SCFSR and check that RDF flag = 1, then read the receive data in SCFRDR, read 1 from the RDF flag, and then clear the RDF flag to 0. The transition of the RDF flag from 0 to 1 can be identified by an RXI interrupt. [3] Serial reception continuation procedure: All data received? Yes Clear RE bit in SCSCR to 0 End of reception [3] To continue serial reception, read at least the receive trigger set number of receive data bytes from SCFRDR, read 1 from the RDF flag, then clear the RDF flag to 0.

The SCIF monitors the transmission line, and if a 0 start bit is detected, performs internal synchronization and starts reception. 2. The received data is stored in SCRSR in LSB-to-MSB order. 3. The parity bit and stop bit are received. After receiving these bits, the SCIF carries out the following checks. A. Stop bit check: The SCIF checks whether the stop bit is 1. If there are two stop bits, only the first is checked. B. The SCIF checks whether receive data can be transferred from the receive shift register (SCRSR) to SCFRDR. C. Overrun check: The SCIF checks that the ORER flag is 0, indicating that the overrun error has not occurred. D. Break check: The SCIF checks that the BRK flag is 0, indicating that the break state is not set. If all the above checks are passed, the receive data is stored in SCFRDR. Note: When a parity error or a framing error occurs, reception is not suspended. 4. If the RIE bit in SCSCR is set to 1 when the RDF or DR flag changes to 1, a receive-FIFOdata-full interrupt (RXI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to 1 when the ER flag changes to 1, a receive-error interrupt (ERI) request is generated. If the RIE bit or the REIE bit in SCSCR is set to 1 when the BRK or ORER flag changes to 1, a break reception interrupt (BRI) request is generated. Figure 15.8 shows an example of the operation for reception.

This mode is suitable for high-speed serial communication. The SCIF transmitter and receiver are independent, so full-duplex communication is possible while sharing the same clock. The transmitter and receiver are also 16-byte FIFO buffered, so continuous transmitting or receiving is possible by reading or writing data while transmitting or receiving is in progress. Figure 15.9 shows the general format in clocked synchronous serial communication.

Data is guaranteed valid at the rising edge of the serial clock. In each character, the serial data bits are transmitted in order from the LSB (first) to the MSB (last). After output of the MSB, the communication line remains in the state of the MSB. In clocked synchronous mode, the SCIF receives data by synchronizing with the rising edge of the serial clock. (1) Transmit/Receive Formats The data length is fixed at eight bits. No parity bit can be added. (2) Clock An internal clock generated by the on-chip baud rate generator by the setting of the C/A bit in SCSMR and CKE[1:0] in SCSCR, or an external clock input from the SCK pin can be selected as the SCIF transmit/receive clock. When the SCIF operates on an internal clock, it outputs the clock signal at the SCK pin. Eight clock pulses are output per transmitted or received character. When the SCIF is not transmitting or receiving, the clock signal remains in the high state. When only receiving, the clock signal outputs while the RE bit of SCSCR is 1 and the number of data in receive FIFO is more than the receive FIFO data trigger number. (3) Transmitting and Receiving Data * SCIF Initialization (Clocked Synchronous Mode) Before transmitting, receiving, or changing the mode or communication format, the software must clear the TE and RE bits to 0 in the serial control register (SCSCR), then initialize the SCIF. Clearing TE to 0 initializes the transmit shift register (SCTSR). Clearing RE to 0, however, does not initialize the RDF, PER, FER, and ORER flags and receive data register (SCRDR), which retain their previous contents.

Be sure to clear the TIE, RIE, TE, and RE bits to 0. [2] Set the data transfer format in SCSMR. [3] Set CKE[1:0]. [4] Write a value corresponding to the bit rate into SCBRR. This is not necessary if an external clock is used. [5] Set the TE or RE bit in SCSCR to 1. Also set the TIE, RIE, and REIE bits to enable the TXD, RXD, and SCK pins to be used. When transmitting, the TXD pin will go to the mark state. When receiving in clocked synchronous mode with the synchronization clock output (clock master) selected, a clock starts to be output from the SCK pin at this point.

When data is written into the transmit FIFO data register (SCFTDR), the SCIF transfers the data from SCFTDR to the transmit shift register (SCTSR) and starts transmitting. Confirm that the TDFE flag in the serial status register (SCFSR) is set to 1 before writing transmit data to SCFTDR. The number of data bytes that can be written is (16 - transmit trigger setting). 2. When data is transferred from SCFTDR to SCTSR and transmission is started, consecutive transmit operations are performed until there is no transmit data left in SCFTDR. When the number of transmit data bytes in SCFTDR falls below the transmit trigger number set in the FIFO control register (SCFCR), the TDFE flag is set. If the TIE bit in the serial control register (SCSR) is set to 1 at this time, a transmit-FIFO-data-empty interrupt (TXI) request is generated. If clock output mode is selected, the SCIF outputs eight synchronous clock pulses. If an external clock source is selected, the SCIF outputs data in synchronization with the input clock. Data is output from the TXD pin in order from the LSB (bit 0) to the MSB (bit 7). 3. The SCIF checks the SCFTDR transmit data at the timing for sending the MSB (bit 7). If data is present, the data is transferred from SCFTDR to SCTSR, and then serial transmission of the next frame is started. If there is no data, the TXD pin holds the state after the TEND flag in SCFSR is set to 1 and the MSB (bit 7) is sent. 4. After the end of serial transmission, the SCK pin is held in the high state. Figure 15.12 shows an example of SCIF transmit operation.

However, the RDF bit is cleared to 0 automatically when an RXI interrupt activates the DMAC to read the data in SCFRDR.

The SCIF synchronizes with serial clock input or output and starts the reception. 2. Receive data is shifted into SCRSR in order from the LSB to the MSB. After receiving the data, the SCIF checks the receive data can be loaded from SCRSR into SCFRDR or not. If this check is passed, the RDF flag is set to 1 and the SCIF stores the received data in SCFRDR. If the check is not passed (overrun error is detected), further reception is prevented. 3. After setting RDF to 1, if the receive FIFO data full interrupt enable bit (RIE) is set to 1 in SCSCR, the SCIF requests a receive-data-full interrupt (RXI). If the ORER bit is set to 1 and the receive-data-full interrupt enable bit (RIE) or the receive error interrupt enable bit (REIE) in SCSCR is also set to 1, the SCIF requests a break interrupt (BRI).

Use the following procedure for the simultaneous transmission/reception of serial data, after enabling the SCIF for transmission/reception. [1] SCIF status check and transmit data write: Read SCFSR and check that the TDFE flag is set to 1, then write transmit data to SCFTDR, read 1 from the TDFE and TEND flags, and clear these flags to 0.

Yes Write transmit data to SCFTDR, read 1 from the TDFE and TEND flags in SCFSR, and clear the TDFE and TEND flags in SCFSR to 0 Read the ORER flag in SCLSR to identify any error, perform the appropriate error handling, then clear the ORER flag to 0. Reception cannot be resumed while the ORER flag is set to 1. [3] SCIF status check and receive data read: Read SCFSR and check that RDF flag = 1, then read the receive data in SCFRDR, and clear the RDF flag to 0. The transition of the RDF flag from 0 to 1 can also be identified by an RXI interrupt. [4] Serial transmission and reception continuation procedure: To continue serial transmission and reception, read 1 from the RDF flag and the receive data in SCFRDR, and clear the RDF flag to 0 before receiving the MSB in the current frame. Similarly, read 1 from the TDFE flag to confirm that writing is possible before transmitting the MSB in the current frame.

Table 15.12 shows the interrupt sources and their order of priority. The interrupt sources are enabled or disabled by means of the TIE, RIE, and REIE bits in SCSCR. A separate interrupt request is sent to the interrupt controller for each of these interrupt sources. When a TXI request is enabled by the TIE bit and the TDFE flag in the serial status register (SCFSR) is set to 1, a TXI interrupt request is generated. The DMAC can be activated and data transfer performed by this TXI interrupt request. At this time, an interrupt request is not sent to the CPU. When an RXI request is enabled by the RIE bit and the RDFE flag or the DR flag in SCFSR is set to 1, an RXI interrupt request is generated. The DMAC can be activated and data transfer performed by this RXI interrupt request. At this time, an interrupt request is not sent to the CPU. The RXI interrupt request caused by the DR flag is generated only in asynchronous mode. When the RIE bit is set to 0 and the REIE bit is set to 1, the SCIF requests only an ERI interrupt without requesting an RXI interrupt. The TXI interrupt indicates that transmit data can be written, and the RXI interrupt indicates that there is receive data in SCFRDR.

After the TDFE flag is set, transmit data up to the number of empty bytes in SCFTDR can be written, allowing efficient continuous transmission. However, if the number of data bytes written in SCFTDR is equal to or less than the transmit trigger number, the TDFE flag will be set to 1 again after being read as 1 and cleared to 0. TDFE flag clearing should therefore be carried out when SCFTDR contains more than the transmit trigger number of transmit data bytes. The number of transmit data bytes in SCFTDR can be found from the upper 8 bits of the FIFO data count register (SCFDR). 15.6.2 SCFRDR Reading and RDF Flag The RDF flag in the serial status register (SCFSR) is set when the number of receive data bytes in the receive FIFO data register (SCFRDR) has become equal to or greater than the receive trigger number set by bits RTRG[1:0] in the FIFO control register (SCFCR). After RDF flag is set, receive data equivalent to the trigger number can be read from SCFRDR, allowing efficient continuous reception. However, if the number of data bytes in SCFRDR exceeds the trigger number, the RDF flag will be set to 1 again if it is cleared to 0. The RDF flag should therefore be cleared to 0 after being read as 1 after reading the number of the received data in the receive FIFO data register (SCFRDR) which is less than the trigger number. The number of receive data bytes in SCFRDR can be found from the lower 8 bits of the FIFO data count register (SCFDR). Rev. 2.00 May. 08, 2008 Page 721 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) 15.6.3 Restriction on DMAC Usage When the DMAC writes data to SCFTDR due to a TXI interrupt request, the state of the TEND flag becomes undefined. Therefore, the TEND flag should not be used as the transfer end flag in such a case. 15.6.4 Break Detection and Processing Break signals can be detected by reading the RXD pin directly when a framing error (FER) is detected. In the break state the input from the RXD pin consists of all 0s, so the FER flag is set and the parity error flag (PER) may also be set. Note that, although transfer of receive data to SCFRDR is halted in the break state, the SCIF receiver continues to operate. 15.6.5 Sending a Break Signal The I/O condition and level of the TXD pin are determined by the SPB2IO and SPB2DT bits in the serial port register (SCSPTR). This feature can be used to send a break signal. Until TE bit is set to 1 (enabling transmission) after initializing, the TXD pin does not work. During the period, mark status is performed by the SPB2DT bit. Therefore, the SPB2IO and SPB2DT bits should be set to 1 (high level output). To send a break signal during serial transmission, clear the SPB2DT bit to 0 (designating low level), then clear the TE bit to 0 (halting transmission). When the TE bit is cleared to 0, the transmitter is initialized regardless of the current transmission state, and 0 is output from the TXD pin.

In reception, the SCIF synchronizes internally with the fall of the start bit, which it samples on the base clock. Receive data is latched at the rising edge of the eighth base clock pulse.* The timing is shown in figure 15.17. 16 clocks 8 clocks 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 Base clock -7.5 clocks Receive data (RxD) Synchronization sampling timing Start bit +7.5 clocks D0 D1 Data sampling timing Figure 15.17 Receive Data Sampling Timing in Asynchronous Mode Note: * This is an example when ABCS = 0 in SCSEMR. When ABCS = 1, a frequency of 8 times the bit rate becomes the basic clock, and receive data is sampled at the fourth rising edge of the basic clock. Rev. 2.00 May. 08, 2008 Page 723 of 1200 REJ09B0344-0200 Section 15 Serial Communication Interface with FIFO (SCIF) The receive margin in asynchronous mode can therefore be expressed as shown in equation 1. Equation 1: M = (0.5 - D - 0.5 1 ) - (L - 0.5) F - (1 + F) x 100 % 2N N Where: M: Receive margin (%) N: Ratio of clock frequency to bit rate (N = 16 when ABCS = 0, and N = 8 when ABCS = 1) D: Clock duty (D = 0 to 1.0) L: Frame length (L = 9 to 12) F: Absolute deviation of clock frequency From equation 1, if F = 0, D = 0.5, and N = 16, the receive margin is 46.875%, as given by equation 2. Equation 2: When D = 0.5 and F = 0: M = (0.5 - 1/(2 x 16)) x 100% = 46.875% This is a theoretical value. A reasonable margin to allow in system designs is 20% to 30%. 15.6.7 FER and PER Flags in the Serial Status Register (SCFSR) The FER (framing error) and PER (parity error) flags in the serial status register (SCFSR) are status flags of the receive FIFO data register (SCFRDR) to be read next. If the CPU or DMAC reads the receive FIFO data register, the FER (framing error) and PER (parity error) flags of the current receive data will be lost. To check the framing error and parity error status of the current receive data correctly, the serial status register (SCFSR) should be read before the receive FIFO data register is read.

However, the configuration of the registers that control the I C bus differs partly from the Philips register configuration. 2 2 2 16.1 Features 2 * Selection of I C format or clocked synchronous serial format * Continuous transmission/reception Since the shift register, transmit data register, and receive data register are independent from each other, the continuous transmission/reception can be performed. I C bus format: * Start and stop conditions generated automatically in master mode * Selection of acknowledge output levels when receiving * Automatic loading of acknowledge bit when transmitting * Bit synchronization/wait function In master mode, the state of SCL is monitored per bit, and the timing is synchronized automatically. If transmission/reception is not yet possible, set the SCL to low until preparations are completed. * Six interrupt sources Transmit data empty (including slave-address match), transmit end, receive data full (including slave-address match), arbitration lost, NACK detection, and stop condition detection * The direct memory access controller (DMAC) can be activated by a transmit-data-empty request or receive-data-full request to transfer data. * Direct bus drive Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive function is selected. Clocked synchronous serial format: * Four interrupt sources Transmit-data-empty, transmit-end, receive-data-full, and overrun error * The direct memory access controller (DMAC) can be activated by a transmit-data-empty request or receive-data-full request to transfer data. 2 Rev. 2.00 May. 08, 2008 Page 725 of 1200 REJ09B0344-0200 Section 16 I2C Bus Interface 3 (IIC3) Figure 16.1 shows a block diagram of the I C bus interface 3. 2 Transfer clock generation circuit SCL Output control Transmission/ reception control circuit ICCR1 ICCR2 ICMR Noise filter ICDRT SAR SDA Output control ICDRS Noise canceler Address comparator ICDRR NF2CYC Bus state decision circuit Arbitration decision circuit [Legend] ICCR1: ICCR2: ICMR: ICSR: ICIER: ICDRT: ICDRR: ICDRS: SAR: NF2CYC: ICIER ICSR I2C bus control register 1 I2C bus control register 2 I2C bus mode register I2C bus status register I2C bus interrupt enable register I2C bus transmit data register I2C bus receive data register I2C bus shift register Slave address register NF2CYC register Interrupt generator Figure 16.1 Block Diagram of I C Bus Interface 3 2 Rev. 2.00 May. 08, 2008 Page 726 of 1200 REJ09B0344-0200 Internal data bus Interrupt request Section 16 I2C Bus Interface 3 (IIC3) 16.2 Input/Output Pins 2 Table 16.1 shows the pin configuration of the I C bus interface 3.

When ICDRT detects the space in the shift register (ICDRS), it transfers the transmit data which is written in ICDRT to ICDRS and starts transferring data. If the next transfer data is written to ICDRT during transferring data of ICDRS, continuous transfer is possible. ICDRT is initialized to H'FF.

When data of one byte is received, ICDRR transfers the receive data from ICDRS to ICDRR and the next data can be received. ICDRR is a receive-only register, therefore the CPU cannot write to this register. ICDRR is initialized to H'FF by a power-on reset.

In transmission, data is transferred from ICDRT to ICDRS and the data is sent from the SDA pin. In reception, data is transferred from ICDRS to ICDRR after data of one byte is received.

For master transmit mode operation timing, refer to figures 16.5 and 16.6. The transmission procedure and operations in master transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Also, set the bits CKS[3:0] in ICCR1. (Initial setting) 2. Read the BBSY flag in ICCR2 to confirm that the bus is released. Set the MST and TRS bits in ICCR1 to select master transmit mode. Then, write 1 to BBSY and 0 to SCP. (Start condition issued) This generates the start condition. 3. After confirming that TDRE in ICSR has been set, write the transmit data (the first byte data show the slave address and R/W) to ICDRT. At this time, TDRE is automatically cleared to 0, and data is transferred from ICDRT to ICDRS. TDRE is set again. 4. When transmission of one byte data is completed while TDRE is 1, TEND in ICSR is set to 1 at the rise of the 9th transmit clock pulse. Read the ACKBR bit in ICIER, and confirm that the slave device has been selected. Then, write second byte data to ICDRT. When ACKBR is 1, the slave device has not been acknowledged, so issue the stop condition. To issue the stop condition, write 0 to BBSY and SCP. SCL is fixed low until the transmit data is prepared or the stop condition is issued. 5. The transmit data after the second byte is written to ICDRT every time TDRE is set. 6. Write the number of bytes to be transmitted to ICDRT. Wait until TEND is set (the end of last byte data transmission) while TDRE is 1, or wait for NACK (NACKF in ICSR = 1) from the receive device while ACKE in ICIER is 1. Then, issue the stop condition to clear TEND or NACKF. 7. When the STOP bit in ICSR is set to 1, the operation returns to slave receive mode.

For master receive mode operation timing, refer to figures 16.7 and 16.8. The reception procedure and operations in master receive mode are shown below. 1. Clear the TEND bit in ICSR to 0, then clear the TRS bit in ICCR1 to 0 to switch from master transmit mode to master receive mode. Then, clear the TDRE bit to 0. 2. When ICDRR is read (dummy data read), reception is started, and the receive clock is output, and data received, in synchronization with the internal clock. The master device outputs the level specified by ACKBT in ICIER to SDA, at the 9th receive clock pulse. 3. After the reception of first frame data is completed, the RDRF bit in ICSR is set to 1 at the rise of 9th receive clock pulse. At this time, the receive data is read by reading ICDRR, and RDRF is cleared to 0. 4. The continuous reception is performed by reading ICDRR every time RDRF is set. If 8th receive clock pulse falls after reading ICDRR by the other processing while RDRF is 1, SCL is fixed low until ICDRR is read. 5. If next frame is the last receive data, set the RCVD bit in ICCR1 to 1 before reading ICDRR. This enables the issuance of the stop condition after the next reception. 6. When the RDRF bit is set to 1 at rise of the 9th receive clock pulse, issue the stage condition. 7. When the STOP bit in ICSR is set to 1, read ICDRR. Then clear the RCVD bit to 0. 8. The operation returns to slave receive mode. Note: If only one byte is received, read ICDRR (dummy-read) after the RCVD bit in ICCR1 is set.

For slave transmit mode operation timing, refer to figures 16.9 and 16.10. The transmission procedure and operations in slave transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches. 2. When the slave address matches in the first frame following detection of the start condition, the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th clock pulse. At this time, if the 8th bit data (R/W) is 1, the TRS bit in ICCR1 and the TDRE bit in ICSR are set to 1, and the mode changes to slave transmit mode automatically. The continuous transmission is performed by writing transmit data to ICDRT every time TDRE is set. 3. If TDRE is set after writing last transmit data to ICDRT, wait until TEND in ICSR is set to 1, with TDRE = 1. When TEND is set, clear TEND. 4. Clear TRS for the end processing, and read ICDRR (dummy read). SCL is opened. 5. Clear TDRE.

For slave receive mode operation timing, refer to figures 16.11 and 16.12. The reception procedure and operations in slave receive mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) Set the MST and TRS bits in ICCR1 to select slave receive mode, and wait until the slave address matches. 2. When the slave address matches in the first frame following detection of the start condition, the slave device outputs the level specified by ACKBT in ICIER to SDA, at the rise of the 9th clock pulse. At the same time, RDRF in ICSR is set to read ICDRR (dummy read). (Since the read data show the slave address and R/W, it is not used.) 3. Read ICDRR every time RDRF is set. If 8th receive clock pulse falls while RDRF is 1, SCL is fixed low until ICDRR is read. The change of the acknowledge before reading ICDRR, to be returned to the master device, is reflected to the next transmit frame. 4. The last byte data is read by reading ICDRR.

When the MST bit in ICCR1 is 1, the transfer clock output from SCL is selected. When MST is 0, the external clock input is selected. (1) Data Transfer Format Figure 16.13 shows the clocked synchronous serial transfer format. The transfer data is output from the fall to the fall of the SCL clock, and the data at the rising edge of the SCL clock is guaranteed. The MLS bit in ICMR sets the order of data transfer, in either the MSB first or LSB first. The output level of SDA can be changed during the transfer wait, by the SDAO bit in ICCR2.

The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For transmit mode operation timing, refer to figure 16.14. The transmission procedure and operations in transmit mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set the MST and CKS[3:0] bits in ICCR1. (Initial setting) 2. Set the TRS bit in ICCR1 to select transmit mode. Then, TDRE in ICSR is set. 3. Confirm that TDRE has been set. Then, write the transmit data to ICDRT. The data is transferred from ICDRT to ICDRS, and TDRE is set automatically. The continuous transmission is performed by writing data to ICDRT every time TDRE is set. When changing from transmit mode to receive mode, clear TRS while TDRE is 1.

The transfer clock is output when MST in ICCR1 is 1, and is input when MST is 0. For receive mode operation timing, refer to figure 16.15. The reception procedure and operations in receive mode are described below. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) 2. When the transfer clock is output, set MST to 1 to start outputting the receive clock. 3. When the receive operation is completed, data is transferred from ICDRS to ICDRR and RDRF in ICSR is set. When MST = 1, the next byte can be received, so the clock is continually output. The continuous reception is performed by reading ICDRR every time RDRF is set. When the 8th clock is risen while RDRF is 1, the overrun is detected and AL/OVE in ICSR is set. At this time, the previous reception data is retained in ICDRR. 4. To stop receiving when MST = 1, set RCVD in ICCR1 to 1, then read ICDRR. Then, SCL is fixed high after receiving the next byte data. Rev. 2.00 May. 08, 2008 Page 755 of 1200 REJ09B0344-0200 Section 16 I2C Bus Interface 3 (IIC3) Notes: Follow the steps below to receive only one byte with MST = 1 specified. See figure 16.16 for the operation timing. 1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting) 2. Set MST = 1 while the RCVD bit in ICCR1 is 0. This causes the receive clock to be output. 3. Check if the BC2 bit in ICMR is set to 1 and then set the RCVD bit in ICCR1 to 1.

Figure 16.17 shows a block diagram of the noise filter circuit. The noise filter consists of three cascaded latches and a match detector. The SCL (or SDA) input signal is sampled on the peripheral clock. When NF2CYC is set to 0, this signal is not passed forward to the next circuit unless the outputs of both latches agree. When NF2CYC is set to 1, this signal is not passed forward to the next circuit unless the outputs of three latches agree. If they do not agree, the previous value is held.

Table 16.4 shows the contents of each interrupt request.

Note that a TXI or RXI interrupt can activate the DMAC if the setting for DMAC activation has been made. In such a case, an interrupt request is not sent to the CPU. Interrupt sources should be cleared in the exception handling. The TDRE and TEND bits are automatically cleared to 0 by writing the transmit data to ICDRT. The RDRF bit is automatically cleared to 0 by reading ICDRR. The TDRE bit is set to 1 again at the same time when the transmit data is written to ICDRT. Therefore, when the TDRE bit is cleared to 0, then an excessive data of one byte may be transmitted.

To prevent this problem, the transfer rate of I C should be specified as equal to or higher than 1/1.8 of the highest transfer rate among the other masters. 16.7.2 Note on Master Receive Mode 2 If ICDRR is read near the falling edge of 8th clock, the receive data will not be received in some cases. In addition, if RCVD is set to 1 near the falling edge of 8th clock, a stop condition cannot be issued in some cases. To prevent these errors, one of the following two methods should be selected. 1. In master receive mode, ICDRR should be read before the falling edge of 8th clock. 2. In master receive mode, RCVD should be set to 1 and the processing should be performed in byte units. 16.7.3 Note on Master Receive Mode with ACKBT Setting In master receive mode operation, ACKBT should be set before the 8th falling edge of SCL in the final data transfer during continuous data transfer. Otherwise, the slave device may overrun. 16.7.4 Note on MST and TRS Bit Status When an Arbitration was Lost If the master transmission is set according to the MST and TRS bit settings while multiple masters are used, the conflicting status in which the AL bit in ICSR is set to 1 in master transmit mode (MST and TRS are set to 1) depending on the arbitration lost generation timing during TRS bit handling instruction execution. This problem can be avoided by the following methods. * When multiple masters are used, the MST and TRS bits should be set by a MOV instruction. * When an arbitration lost occurs, check if both MST and TRS bits are cleared to 0. If either or both of MST and TRS bits are not cleared to 0, both the bits should be cleared to 0.

In single-cycle scan mode, A/D conversion is performed once on one or more specified channels and then it ends. In continuous scan mode, the A/D conversion is performed sequentially on one or more specified channels until the ADST bit is cleared to 0. The ADCS bit in the A/D control register (ADCR) is used to select the operating mode. Setting the ADCS bit to 0 selects single-cycle scan mode and setting the ADCS bit to 1 selects continuous scan mode. In both modes, A/D conversion starts on the channel with the lowest number in the analog input channels selected by the A/D analog input channel select register (ADANSR) from AN0 to AN7. In single-cycle scan mode, when one cycle of A/D conversion on all specified channels is completed, the ADF bit in ADSR is set to 1 and the ADST bit is automatically cleared to 0. In continuous scan mode, when conversion on all specified channels is completed, the ADF bit in ADSR is set to 1. To stop A/D conversion, write 0 to the ADST bit. When the ADF bit is set to 1, if the ADIE bit in ADCR is set to 1, an A/D conversion end interrupt (ADI) is generated. When clearing the ADF bit to 0, read the ADF bit while set to 1 and then write 0. However, when the DMAC is activated by an ADI interrupt, the ADF bit is automatically cleared to 0. 17.4.1 Single-Cycle Scan Mode The following example shows the operation when analog input channels 0 to 3 (AN0 to AN3) are selected and the A/D conversion is performed in single-cycle scan mode using four channels. 1. Set the ADCS bit in the A/D control register (ADCR) to 0. 2. Set all bits ANS0 to ANS3 in the A/D analog input channel select register (ADANSR) to 1. 3. Set the ADST bit in the A/D control register (ADCR) to 1 to start A/D conversion. 4. After channels 0 to 2 (GrA) are sampled simultaneously, offset canceling processing (OFC) is performed. Then, A/D conversion is performed on channel 0. Upon completion of the A/D conversion, the A/D conversion result is transferred to ADDR0. Following this, channel 1 is converted. Upon completion of the conversion, the A/D conversion result is transferred to ADDR1. In the same way, channel 2 is converted and the A/D conversion result is transferred to ADDR2. A/D conversion of channel 3 is then started. Upon completion of the A/D conversion, the A/D conversion result is transferred to ADDR3.

When A/D conversion ends on all specified channels (AN0 to AN3), the ADF bit is set to 1, the ADST bit is automatically cleared to 0, and the A/D conversion ends.

This operation also applies to the A/D_1 conversion. 1. Set the ADCS bit in the A/D control register (ADCR) to 0. 2. Set all bits of ANS0, ANS2, and ANS3 in the A/D analog input channel select register (ADANSR) to 1. 3. Set the ADST bit in the A/D control register (ADCR) to 1 to start A/D conversion. 4. Channels 0 and 2 (GrA) are sampled simultaneously. As the ANS1 bit in ADANSR is set to 0, channel 1 is not sampled. After this, offset canceling processing (OFC) is performed. Then the A/D conversion on channel 0 is started. Upon completion of the A/D conversion, the A/D conversion result is transferred to ADDR0. In the same way, channel 2 is converted and the A/D conversion result is transferred to ADDR2. The A/D conversion is not performed on channel 1. 5. The A/D conversion of channel 3 starts. Upon completion of the A/D conversion, the A/D conversion result is transferred to ADDR3. 6. When the A/D conversion ends on all the specified channels (AN0 to AN3), the ADF bit is set to 1. At this time, if the ADIE bit is set to 1, an ADI interrupt is generated after the A/D conversion. 7. Steps 4 to 6 are repeated as long as the ADST bit remains set to 1. When the ADST bit is cleared to 0, the A/D conversion stops. After this, if the ADST bit is set to 1, the A/D conversion starts again and repeats steps 4 to 6.

Each of channels 0 to 2 of the A/D converter has a dedicated built-in sample-and-hold circuit. Channels 0 to 2 can be simultaneously sampled as one group. This group is referred to as Group A (GrA) (in table 17.5). Even when only one channel is selected in the group by ADANSR, the sample-andhold operation is performed with the dedicated sample-and-hold circuit. When only the channels without a dedicated sample-and-hold circuit are specified by ADANSR, the time that elapses is the same as when a dedicated sample-and-hold circuit is used. When an event that sets the ADST bit, for example, writing to this bit by the CPU, A/D converter activation request from the MTU2, the MTU2S, or an external trigger signal occurs, the analog input is sampled by the dedicated sample-and-hold circuit for each channel after the A/D conversion start delay time (tD) has passed and the offset canceling processing (OFC) is performed. After this, the sampling of the analog input using the sample-and-hold circuit common to all the channels is performed and then the A/D conversion is started. Figure 17.4 shows the A/D conversion timing in this case. This A/D conversion time (tCONV) includes the tD, the offset canceling processing time (tOFC), the analog input sampling time with a dedicated sample-and-hold circuit for each channel (tSPLSH), and the analog input sampling time with the sample-and-hold circuit common to all the channels (tSPL). The tSPLSH does not depend on the number of channels simultaneously sampled. In continuous scan mode, the A/D conversion time (tCONV) given in table 17.6 applies to the conversion time of the first cycle. The conversion time of the second and subsequent cycles is expressed as (tCONV - tD + 6).

To enable this function, set the TRGE bit in ADCR to 1 and clear the EXTRG bit to 0. After this setting is made, if an A/D conversion start trigger from the MTU2 or MTU2S is generated, the ADST bit is set to 1. The timing between the setting of the ADST bit and the start of the A/D conversion is the same for all A/D conversion activation sources. The A/D conversion start trigger must be input after ADCR, ADSTRGR, and ADANSR registers have been set. Rev. 2.00 May. 08, 2008 Page 787 of 1200 REJ09B0344-0200 Section 17 A/D Converter (ADC) 17.4.5 External Trigger Input Timing The A/D conversion can be externally triggered. To input an external trigger, set the pin function controller (PFC) to select ADTRG pin function and drive the ADTRG pin low when a high level is input to the ADTRG pin with the TRGE and EXTRG bits in ADCR are both set to 1. A falling edge of the ADTRG pin sets the ADST bit in ADCR to 1, starting the A/D conversion. Other operations are conducted in the same way for all A/D conversion activation sources. Figure 17.5 shows the timing. The ADST bit is set to 1 after 5 states has elapsed from the point at which the A/D converter detects a falling edge on the ADTRG pin. A low level input to the ADTRG pin must be made after the ADCR, ADSTRGR, and ADANSR registers have been set.

This function allows the detection of nonupdated ADDR states. Figure 17.6 shows an example of when the auto-clear function of ADDR is disabled (normal state) and enabled. Rev. 2.00 May. 08, 2008 Page 788 of 1200 REJ09B0344-0200 Section 17 A/D Converter (ADC) When the ACE bit is 0 (initial value) and the A/D conversion result (H'0222) is not written to ADDR for some reason, the old data (H'0111) becomes the ADDR value. In addition, when the ADDR value is read into a general register using an A/D conversion end interrupt, the old data (H'0111) is stored in the general register. To detect a renewal failure, every time the old data needs to be stored in the RAM, a general register, etc. When the ACE bit is 1, reading ADDR = H'0111 by the CPU or DMAC automatically clears ADDR to H'0000. After this, if the A/D conversion result (H'0222) cannot be transferred to ADDR for some reason, the cleared data (H'0000) remains as the ADDR value. When this ADDR value is read into a general register, H'0000 is stored in the general register. Just by checking whether the read data value is H'0000 or not allows the detection of non-updated ADDR states. * ACE bit = 0 (Normal condition: Auto-clear function is disabled.)

An ADI interrupt generation is enabled when the ADIE bit in ADCR is set to 1. The DMAC can be activated by the DMAC setting when an ADI interrupt is generated. At this time, no interrupt to the CPU is generated. When the DMAC is activated by an ADI interrupt, the ADF bit in ADSR is automatically cleared at the data transfer by the DMAC.

When the A/D converter is not used, set Vcc AVcc 5.0V 0.5V, AVss = Vss, and do not leave the AVcc pin open. 17.7.3 Range of AVREF Pin Settings Set AVREF = AVcc 0.3 V and AVREFVss = AVss 0.3 V. If these conditions are not met, the reliability of the LSI may be adversely affected. 17.7.4 Notes on Board Design In board design, digital circuitry and analog circuitry should be as mutually isolated as possible, and the layout in which the digital circuit signal lines and analog circuit signal lines cross or are in close proximity to each other should be avoided as much as possible. Failure to do so may result in the incorrect operation of the analog circuitry due to inductance, adversely affecting the A/D conversion values. Also, digital circuitry must be isolated from the analog input signals (AN0 to AN7), analog reference power supply (AVREF), the analog power supply (AVcc), the analog ground (AVss), and the analog reference ground (AVREFVss). Also, AVss should be connected at one point to a stable digital ground (Vss) on the board.

The AVREFVss and AVss should be the same voltage. Also, the bypass capacitors connected to AVREF and the filter capacitor connected to ANn should be connected to the AVss. If a filter capacitor is connected as shown in figure 17.8, the input currents at the analog input pin (ANn) are averaged, and an error may occur. Careful consideration is therefore required when deciding the circuit constants. 4.5 V to 5.5 V 10 F GND 0.1 F AVCC AVSS AVREFH 0.1 F AVREFVSS SH7211F Analog input pin (channel 0 to 7) AN0 to AN7 100 0.1 F Figure 17.8 Example of Analog Input Pin Protection Circuit 17.7.6 Notes on Register Setting * Set the ADST bit in the A/D control register (ADCR) after the A/D start trigger select register (ADSTRGR) and the A/D analog input channel select register (ADANSR) have been set.

For details, see section 23, Power-Down Modes. 18.5.2 D/A Output Hold Function in Software Standby Mode When this LSI enters software standby mode with D/A conversion enabled, the D/A outputs are retained, and the analog power supply current is equal to as during D/A conversion. If the analog power supply current needs to be reduced in software standby mode, clear the DAOE0, DAOE1, and DAE bits to 0 to disable the D/A outputs. 18.5.3 Setting Analog Input Voltage The reliability of this LSI may be adversely affected if the following voltage ranges are exceeded. 1. AVcc and AVss input voltages Input voltages AVcc and AVss should be Vcc AVcc 5.0 V 0.5 V and AVss = Vss. Do not leave the AVcc and AVss pins open when the A/D converter or D/A converter is not in use and in software standby mode. When not in use, connect AVcc to the power supply (VccQ) and AVss to the ground (VssQ). 2. Setting range of AVREF input voltage Set the voltage range of the AVREF pin as AVREF = AVcc 0.3 V when the A/D converter or D/A converter is used, or as AVREF = AVcc when no A/D converter or D/A converter is used.

Bits PA25IOR to PA0IOR correspond to pins PA25 to PA0. PAIORH and PAIORL are enabled when the port A pins are functioning as general-purpose inputs/outputs (PA25 to PA0) and for the TIOC input/output of the MTU2. In other states, they are disabled. A given pin on port A will be an output pin if the corresponding bit in PAIORH or PAIORL is set to 1, and an input pin if the bit is cleared to 0. Bits 15 to 10 of PAIORH are reserved. These bits are always read as 0. The write value should always be 0. PAIORH and PAIORL are initialized to H'0000 by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby mode.

Bits PB30IOR to PB0IOR correspond to pins PB30 to PB0, respectively. PBIOR is enabled when the port B pins are functioning as general-purpose inputs/outputs (PB9, PB5, and PB4). In other states, PBIOR is disabled. A given pin on port B will be an output pin if the corresponding bit in PBIORH and PBIORL is set to 1, and an input pin if the bit is cleared to 0. Bit 15 of PBIORH is reserved. This bit is always read as 0. The write value should always be 0. PBIORH and PBIORL are initialized to H'0000 by a power-on reset; but are not initialized by a manual reset or in sleep mode or software standby mode.

Bits PD15IOR to PD0IOR correspond to pins PD15 to PD0. PDIOR is enabled when the port D pins are functioning as general-purpose inputs/outputs (PD15 to PD0). In other states, PDIOR is disabled. A given pin on port D will be an output pin if the corresponding bit in PDIOR is set to 1, and an input pin if the bit is cleared to 0. PDIOR is initialized to H'0000 by a power-on; but is not initialized by a manual reset or in sleep mode or software standby mode.

Bits PA25DR to PA0DR correspond to pins PA25 to PA0, respectively. When a pin function is general output, if a value is written to PADRH or PADRL, the value is output directly from the pin, and if PADRH or PADRL is read, the register value is returned directly regardless of the pin state. When a pin function is general input, if PADRH or PADRL is read, the pin state, not the register value, is returned directly. If a value is written to PADRH or PADRL, although that value is written into PADRH or PADRL, it does not affect the pin state. Table 20.2 summarizes PADRH and PADRL read/write operations. PADRH and PADRL are initialized to the respective values shown in table 20.1 by a power-on reset. PADRH and PADRL are not initialized by a manual reset or in sleep mode or software standby mode.

The flash memory has the following features. 21.1 Features * Two flash-memory MATs, with one selected by the mode in which the LSI starts up The on-chip flash memory has two memory spaces in the same address space (hereafter referred to as memory MATs). The mode setting when the LSI starts up determines the memory MAT that is currently mapped. The MAT can be switched by bank-switching after the LSI has started up. Size of the user MAT, from which booting-up proceeds after a power-on reset in user mode: 512 kbytes Size of the user boot MAT, from which booting-up proceeds after a power-on reset in user boot mode: 12 kbytes * Three on-board programming modes and one off-board programming mode On-board programming modes Boot Mode: The on-chip SCIF interface is used for programming in this mode. Either the user MAT or user-boot MAT can be programmed, and the bit rate for data transfer between the host and this LSI are automatically adjusted. User Program Mode: This mode allows programming of the user MAT via any desired interface. User Boot Mode: This mode allows writing of a user boot program via any desired interface and programming of the user MAT. Off-board programming mode Programmer Mode: This mode allows programming of the user MAT and user boot MAT with the aid of a PROM programmer. * Downloading of an on-chip program to provide an interface for programming/erasure This LSI has a dedicated programming/erasing program. After this program has been downloaded to the on-chip RAM, programming or erasing can be performed by setting parameters as arguments. "User branching" is also supported. Rev. 2.00 May. 08, 2008 Page 885 of 1200 REJ09B0344-0200 Section 21 Flash Memory User branching Programming is performed in 256-byte units. Each round of programming consists of application of the programming pulse, reading for verification, and several other steps. Erasing is performed in block units and each round of erasing consists of several steps. A userprocessing routine can be executed between each round of erasing, and making the setting for this is called the addition of a user branch. * Protection modes There are two modes of protection: software protection is applied by register settings and hardware protection is applied by the level on the FWE pin. Protection of the flash memory from programming or erasure can be selected. When an abnormal state is detected, such as runaway execution of programming/erasing, the protection modes initiate the transition to the error protection state and suspend programming/erasing processing. * Programming/erasing time The time taken to program 256 bytes of flash memory in a single round is 2 ms (typ.), which is equivalent to 7.8 s per byte. The erasing time is 80 ms (typ.) per 8-Kbyte block, 600 ms (typ.) per 64-Kbyte block, and 1200 ms (typ.) per 128-Kbyte block. * Number of programming operations The flash memory can be programmed up to 100 times. * Operating frequency for programming/erasing The operating frequency range for programming/erasing I = 32 to 40 MHz Rev. 2.00 May. 08, 2008 Page 886 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.2 21.2.1 Overview Block Diagram ROM cache address bus ROM cache data bus (128 bits) FCCS FPCS Module bus FECS FKEY FMATS FTDAR Control unit Memory MAT unit User MAT: 512 kbytes User boot MAT: 12 kbytes Flash memory FWE pin Mode pins Operating mode [Legend] FCCS: FPCS: FECS: FKEY: FMATS: FTDAR: Flash code control and status register Flash program code select register Flash erase code select register Flash key code register Flash MAT select register Flash transfer destination address register Figure 21.1 Block Diagram of Flash Memory Rev. 2.00 May. 08, 2008 Page 887 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.2.2 Operating Mode When each mode pin and the FWE pin are set in the reset state and the reset signal is released, the microcontroller enters each operating mode as shown in figure 21.2.

The start address is allocated to the same address in the user MAT and user boot MAT. Therefore, when the program execution or data access is performed between the two MATs, the MAT must be switched by using FMATS. The user MAT or user boot MAT can be read in all modes if it is in ROM valid mode. However, the user boot MAT can be programmed only in boot mode and programmer mode. 512 kbytes Address H'0007FFFF Figure 21.3 Flash Memory Configuration The user MAT and user boot MAT have different memory sizes. Do not access a user boot MAT that is 12 kbytes or more. When a user boot MAT exceeding 12 kbytes is read from, an undefined value is read.

The procedure program is made by the user in user program mode and user boot mode. The overview of the procedure is as follows. For details, see section 21.5.2, User Program Mode. Start user procedure program for programming/erasing. Select on-chip program to be downloaded and set download destination Download on-chip program by setting VBR, FKEY, and SCO bits. Initialization execution (on-chip program execution) Programming (in 256-byte units) or erasing (in one-block units) (on-chip program execution) No Programming/ erasing completed? Yes End user procedure program Figure 21.5 Overview of User Procedure Program (1) Selection of On-Chip Program to be Downloaded and Setting of Download Destination This LSI has programming/erasing programs and they can be downloaded to the on-chip RAM. The on-chip program to be downloaded is selected by setting the corresponding bits in the programming/erasing interface registers. The download destination can be specified by FTDAR. Rev. 2.00 May. 08, 2008 Page 893 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2) Download of On-Chip Program The on-chip program is automatically downloaded by clearing VBR of the CPU to H'80000000 and then setting the SCO bit in the flash code control and status register (FCCS) and the flash key code register (FKEY), which are programming/erasing interface registers. The user MAT is replaced to the embedded program storage area when downloading. Since the flash memory cannot be read when programming/erasing, the procedure program, which is working from download to completion of programming/erasing, must be executed in a space other than the flash memory to be programmed/erased (for example, on-chip RAM). Since the result of download is returned to the programming/erasing interface parameters, whether the normal download is executed or not can be confirmed. Note that VBR can be changed after download is completed. (3) Initialization of Programming/Erasing The operating frequency and user branch are set before execution of programming/erasing. The user branch destination must be in an area other than the user MAT area which is in the middle of programming and the area where the on-chip program is downloaded. These settings are performed by using the programming/erasing interface parameters. (4) Programming/Erasing Execution To program or erase, the FWE pin must be brought high and user program mode must be entered. The program data/programming destination address is specified in 256-byte units when programming. The block to be erased is specified in erase-block units when erasing. These specifications are set by using the programming/erasing interface parameters and the onchip program is initiated. The on-chip program is executed by using the JSR or BSR instruction to perform the subroutine call of the specified address in the on-chip RAM. The execution result is returned to the programming/erasing interface parameters. The area to be programmed must be erased in advance when programming flash memory. There are limitations and notes on the interrupt processing during programming/erasing. For details, see section 21.7.2, Interrupts during Programming/Erasing. (5) When Programming/Erasing is Executed Consecutively When the processing is not ended by the 256-byte programming or one-block erasure, the program address/data and erase-block number must be updated and consecutive programming/erasing is required. Since the downloaded on-chip program is left in the on-chip RAM after the processing, download and initialization are not required when the same processing is executed consecutively.

They are all 8-bit registers that can be accessed in bytes. (1) Flash Code Control and Status Register (FCCS) FCCS is configured by bits which request the monitor of the FWE pin state and error occurrence during programming or erasing flash memory and the download of the on-chip program.

When FLER is set to 1, flash memory enters the error protection state. When FLER is set to 1, high voltage is applied to the internal flash memory. To reduce the damage to flash memory, the reset signal must be released after the reset period of 100 s which is longer than normal. 0: Flash memory operates normally Programming/erasing protection for flash memory (error protection) is invalid. [Clearing condition] At a power-on reset 1: Indicates an error occurs during programming/erasing flash memory. Programming/erasing protection for flash memory (error protection) is valid.

When this bit is set to 1, the on-chip program which is selected by FPCS/FECS is automatically downloaded in the on-chip RAM area specified by FTDAR. In order to set this bit to 1, H'A5 must be written to FKEY and this operation must be in the on-chip RAM. Thirty-two NOP instructions must be executed immediately after setting this bit to 1. For interrupts during download, see section 21.7.2, Interrupts during Programming/Erasing. For the download time, see section 21.7.3, Other Notes. Since this bit is cleared to 0 when download is completed, this bit cannot be read as 1. Download by setting the SCO bit to 1 requires a special interrupt processing that performs bank switching to the on-chip program storage area. Therefore, before issuing a download request (SCO = 1), set VBR to H'80000000. Otherwise, the CPU gets out of control. Once download end is confirmed, VBR can be changed to any other value. The mode in which the FWE pin is high must be used when using the SCO function. 0: Download of the on-chip programming/erasing program to the on-chip RAM is not executed.

When a value other than H'A5 is written to FKEY, 1 cannot be written to the SCO bit. Therefore downloading to the on-chip RAM cannot be executed. Only when H'5A is written, programming/erasing of flash memory can be executed. Even if the on-chip programming/erasing program is executed, flash memory cannot be programmed or erased when a value other than H'5A is written to FKEY. H'A5: Writing to the SCO bit is enabled (The SCO bit cannot be set by a value other than H'A5.) H'5A: Programming/erasing is enabled (A value other than H'5A enables software protection state.)

The MAT is switched by writing a value in FMATS with the on-chip RAM instruction. When the MAT is switched, follow section 21.7.1, Switching between User MAT and User Boot MAT. (The user boot MAT cannot be programmed in user program mode if user boot MAT is selected by FMATS. The user boot MAT must be programmed in boot mode or in programmer mode.) H'AA: The user boot MAT is selected (in user-MAT selection state when the value of these bits are other than H'AA) Initial value when these bits are initiated in user boot mode. H'00: Initial value when these bits are initiated in a mode except for user boot mode (in user-MAT selection state) [Programmable condition] These bits are in the execution state in the on-chip RAM.

Whether the address setting is erroneous or not is tested by checking whether the setting of TDA6 to TDA0 is in the range of H'00 to H'05 after setting the SCO bit in FCCS to 1 and performing download. Before setting the SCO bit to 1 be sure to set the FTDAR value between H'00 to H'05 as well as clearing this bit to 0. 0: Setting of TDA6 to TDA0 is normal 1: Setting of TDER and TDA6 to TDA0 is H'06 to H'FF and download has been aborted 6 to 0 TDA[6:0] All 0 R/W Transfer Destination Address These bits specify the download start address. A value from H'00 to H'05 can be set to specify the download start address in on-chip RAM in 2-kbyte units. A value from H'06 to H'7F cannot be set. If such a value is set, the TDER bit (bit 7) in this register is set to 1 to prevent download from being executed. H'00: Download start address is set to H'FFF81000 H'01: Download start address is set to H'FFF81800 H'02: Download start address is set to H'FFF82000 H'03: Download start address is set to H'FFF82800 H'04: Download start address is set to H'FFF83000 H'05: Download start address is set to H'FFF83800 H'06 to H'7F: Setting prohibited. If this value is set, the TDER bit (bit 7) is set to 1 to abort the download processing. Rev. 2.00 May. 08, 2008 Page 904 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.4.3 Programming/Erasing Interface Parameters The programming/erasing interface parameters specify the operating frequency, user branch destination address, storage place for program data, programming destination address, and erase block and exchanges the processing result for the downloaded on-chip program. This parameter uses the general registers of the CPU (R4, R5, and R0) or the on-chip RAM area. The initial value is undefined. At download all CPU registers are stored, and at initialization or when the on-chip program is executed, CPU registers except for R0 are stored. The return value of the processing result is written in R0. Since the stack area is used for storing the registers or as a work area, the stack area must be saved at the processing start. (The maximum size of a stack area to be used is 128 bytes.) The programming/erasing interface parameters are used in the following four items. 1. Download control 2. Initialization before programming or erasing 3. Programming 4. Erasing These items use different parameters. The correspondence table is shown in table 21.6. The processing results of initialization, programming, and erasing are returned, but the bit contents have different meanings according to the processing program. See the description of FPFR for each processing.

The on-chip RAM area to be downloaded is the area as much as 3 kbytes starting from the start address specified by FTDAR. For the address map of the on-chip RAM, see figure 21.10. The download control is set by using the programming/erasing interface registers. The return value is given by the DPFR parameter. (a) Download Pass/Fail Result Parameter (DPFR: One Byte of Start Address of On-Chip RAM Specified by FTDAR) This parameter indicates the return value of the download result. The value of this parameter can be used to determine if downloading is executed or not. Since the confirmation whether the SCO bit is set to 1 is difficult, the certain determination must be performed by setting one byte of the start address of the on-chip RAM area specified by FTDAR to a value other than the return value of download (for example, H'FF) before the download start (before setting the SCO bit to 1).

The specified period pulse must be applied when programming or erasing. The specified pulse width is made by the method in which wait loop is configured by the CPU instruction. The operating frequency of the CPU must be set. Since the user branch function is supported, the user branch destination address must be set. The initial program is set as a parameter of the programming/erasing program which has downloaded these settings.

The user branch destination must be an area other than the flash memory, an area other than the RAM area in which on-chip program has been transferred, or the external bus space. Note that the CPU must not branch to an area without the execution code and get out of control. The on-chip program download area and stack area must not be overwritten. If CPU runaway occurs or the download area or stack area is overwritten, the value of flash memory cannot be guaranteed. The download of the on-chip program, initialization, initiation of the programming/erasing program must not be executed in the processing of the user branch destination. Programming or erasing cannot be guaranteed when returning from the user branch destination. The program data which has already been prepared must not be programmed. Store general registers R8 to R15. General registers R0 to R7 are available without storing them. Moreover, the programming/erasing interface registers must not be written to in the processing of the user branch destination. After the processing of the user branch has ended, the programming/erasing program must be returned to by using the RTS instruction.

The start address of the programming destination on the user MAT is set in general register R5 of the CPU. This parameter is called FMPAR (flash multipurpose address area parameter). Since the program data is always in 256-byte units, the lower eight bits (MOA7 to MOA0) must be H'00 as the boundary of the programming start address on the user MAT. 2. The program data for the user MAT must be prepared in the consecutive area. The program data must be in the consecutive space which can be accessed by using the MOV.B instruction of the CPU and is not the flash memory space. When data to be programmed does not satisfy 256 bytes, the 256-byte program data must be prepared by embedding the dummy code (H'FF). The start address of the area in which the prepared program data is stored must be set in general register R4. This parameter is called FMPDR (flash multipurpose data destination area parameter). For details on the programming procedure, see section 21.5.2, User Program Mode. (3.1) Flash Multipurpose Address Area Parameter (FMPAR: General Register R5 of CPU) This parameter indicates the start address of the programming destination on the user MAT. When an address in an area other than the flash memory space is set, an error occurs. The start address of the programming destination must be at the 256-byte boundary.

On-board programming mode has three operating modes: user program mode, user boot mode, and boot mode. For details on the pin setting for entering each mode, see table 21.1. For details on the state transition of each mode for flash memory, see figure 21.2. 21.5.1 Boot Mode Boot mode executes programming/erasing user MAT and user boot MAT by means of the control command and program data transmitted from the host using the on-chip SCI. The tool for transmitting the control command and program data must be prepared in the host. The SCI communication mode is set to asynchronous mode. When reset start is executed after this LSI's pin is set in boot mode, the boot program in the microcontroller is initiated. After the SCI bit rate is automatically adjusted, the communication with the host is executed by means of the control command method. The system configuration diagram in boot mode is shown in figure 21.6. For details on the pin setting in boot mode, see table 21.1. Interrupts are ignored in boot mode, so do not generate them.

The SCIF transmit/receive format is set to 8-bit data, 1 stop bit, and no parity. This LSI calculates the bit rate of transmission by the host by means of the measured low period and transmits the bit adjustment end sign (1 byte of H'00) to the host. The host must confirm that this bit adjustment end sign (H'00) has been received normally and transmits 1 byte of H'55 to this LSI. When reception is not executed normally, boot mode is initiated again (reset) and the operation described above must be executed. The bit rate between the host and this LSI is not matched because of the bit rate of transmission by the host and system clock frequency of this LSI. To operate the SCIF normally, the transfer bit rate of the host must be set to 9,600 bps or 19,200 bps. The system clock frequency which can automatically adjust the transfer bit rate of the host and the bit rate of this LSI is shown in table 21.7.

For details on boot mode, see section 21.8.1, Specifications of the Standard Serial Communications Interface in Boot Mode. 1. Bit-rate matching After the chip has been started up in boot mode, bit-rate matching between the SCI and the host proceeds. 2. Waiting for inquiry and selection commands The chip sends the requested information to the host in response to inquiries regarding the size and configuration of the user MAT, start addresses of the MATs, information on supported devices, etc. 3. Automatic erasure of the entire user MAT and user boot MAT After all necessary inquiries and selections have been made and the command for transition to the programming/erasure state is sent by the host, the entire user MAT and user boot MAT are automatically erased. 4. Waiting for programming/erasure command On receiving the programming selection command, the chip waits for data to be programmed. To program data, the host transmits the programming command code followed by the address where programming should start and the data to be programmed. This is repeated as required while the chip is in the programming-selected state. To terminate programming, H'FFFFFFFF should be transmitted as the first address of the area for programming. This makes the chip return to the programming/erasure command waiting state from the programming data waiting state. On receiving the erasure select command, the chip waits for the block number of a block to be erased. To erase a block, the host transmits the erasure command code followed by the number of the block to be erased. This is repeated as required while the chip is in the erasure-selected state. To terminate erasure, H'FF should be transmitted as the block number. This makes the chip return to the programming/erasure command waiting state from the erasure block number waiting state. Erasure should only be executed when a specific block is to be reprogrammed without executing a reset-start of the chip after the flash memory has been programmed in boot mode. If all desired programming is done in a single operation, such erasure processing is not necessary because all blocks are erased before the chip enters the programming/erasure/other command waiting state. In addition to the programming and erasure commands, commands for sum checking and blank checking (checking for erasure) of the user MAT and user boot MAT, reading data from the user MAT/user boot MAT, and acquiring current state information are provided.

(The user boot MAT cannot be programmed/erased.) Programming/erasing is executed by downloading the program in the microcontroller. The overview flow is shown in figure 21.9. High voltage is applied to internal flash memory during the programming/erasing processing. Therefore, transition to reset must not be executed. Doing so may cause damage or destroy flash memory. If reset is executed accidentally, the reset signal must be released after the reset input period, which is longer than the normal 100 s. For details on the programming procedure, see the description in section 21.5.2 (2), Programming Procedure in User Program Mode. For details on the erasing procedure, see the description in section 21.5.2 (3), Erasing Procedure in User Program Mode. For the overview of a processing that repeats erasing and programming by downloading the programming program and the erasing program in separate on-chip ROM areas using FTDAR, see the description in section 21.5.2 (4), Erasing and Programming Procedure in User Program Mode. Programming/erasing start When programming, program data is prepared 1. Inputting high level to the FWE pin sets the FWE bit to 1. 2. Programming/erasing is executed only in the on-chip RAM. However, if the program data is in a consecutive area and can be accessed by the MOV.B instruction of the CPU like SRAM/ROM, the program data can be in an external space. 3. After programming/erasing is finished, low level must be input to the FWE pin for protection. FWE=1 ?

The procedure program must be executed in an area other than the flash memory to be programmed. Especially the part where the SCO bit in FCCS is set to 1 for downloading must be executed in the on-chip RAM. Specify 4:4:4 as the frequency division ratios of an internal clock (I), a bus clock (B), and a peripheral clock (P) through the frequency control register (FRQCR). The area that can be executed in the steps of the user procedure program (on-chip RAM, user MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program and Data for Programming. Rev. 2.00 May. 08, 2008 Page 926 of 1200 REJ09B0344-0200 Section 21 Flash Memory The following description assumes the area to be programmed on the user MAT is erased and program data is prepared in the consecutive area. When erasing has not been executed, carry out erasing before writing. 256-byte programming is performed in one program processing. When more than 256-byte programming is performed, programming destination address/program data parameter is updated in 256-byte units and programming is repeated. When less than 256-byte programming is performed, data must total 256 bytes by adding the invalid data. If the invalid data to be added is H'FF, the program processing period can be shortened. (2.1) Select the on-chip program to be downloaded When the PPVS bit of FPCS is set to 1, the programming program is selected. Several programming/erasing programs cannot be selected at one time. If several programs are set, download is not performed and a download error is returned to the source select error detect (SS) bit in the DPFR parameter. Specify the start address of the download destination by FTDAR. (2.2) Write H'A5 in FKEY If H'A5 is not written to FKEY for protection, 1 cannot be written to the SCO bit for a download request. (2.3) VBR is set to 0 and 1 is written to the SCO bit of FCCS, and then download is executed. VBR must always be set to H'80000000 before setting the SCO bit to 1. To write 1 to the SCO bit, the following conditions must be satisfied. * H'A5 is written to FKEY. * The SCO bit writing is executed in the on-chip RAM. When the SCO bit is set to 1, download is started automatically. When execution returns to the user procedure program, the SCO bit is cleared to 0. Therefore, the SCO bit cannot be confirmed to be 1 in the user procedure program. The download result can be confirmed only by the return value of the DPFR parameter. Before the SCO bit is set to 1, incorrect decision must be prevented by setting the DPFR parameter, that is one byte of the start address of the on-chip RAM area specified by FTDAR, to a value other than the return value (H'FF). When download is executed, particular interrupt processing, which is accompanied by the bank switch as described below, is performed as an internal microcontroller processing, so VBR need to be set to H'80000000. Thirty-two NOP instructions are executed immediately after the instructions that set the SCO bit to 1. Rev. 2.00 May. 08, 2008 Page 927 of 1200 REJ09B0344-0200 Section 21 Flash Memory 1. The user MAT space is switched to the on-chip program storage area. 2. After the selection condition of the download program and the address set in FTDAR are checked, the transfer processing is executed starting to the on-chip RAM address specified by FTDAR. 3. The SCO bits in FCCS, FPCS, and FECS are cleared to 0. 4. The return value is set to the DPFR parameter. 5. After the on-chip program storage area is returned to the user MAT space, execution returns to the user procedure program. After download is completed and the user procedure program is running, the VBR setting can be changed. The notes on download are as follows. In the download processing, the values of the general registers of the CPU are retained. During the download processing, interrupts must not be generated. For details on the relationship between download and interrupts, see section 21.7.2, Interrupts during Programming/Erasing. Since a stack area of maximum 256 bytes is used, an area of at least 128 bytes must be saved before setting the SCO bit to 1. If flash memory is accessed by the DMAC during downloading, operation cannot be guaranteed. Therefore, access by the DMAC must not be executed. (2.4) FKEY is cleared to H'00 for protection. (2.5) The value of the DPFR parameter must be checked to confirm the download result. A recommended procedure for confirming the download result is shown below. 1. Check the value of the DPFR parameter (one byte of start address of the download destination specified by FTDAR). If the value is H'00, download has been performed normally. If the value is not H'00, the source that caused download to fail can be investigated by the description below. 2. If the value of the DPFR parameter is the same as before downloading (e.g. H'FF), the address setting of the download destination in FTDAR may be abnormal. In this case, confirm the setting of the TDER bit (bit 7) in FTDAR. 3. If the value of the DPFR parameter is different from before downloading, check the SS bit (bit 2) and the FK bit (bit 1) in the DPFR parameter to ensure that the download program selection and FKEY register setting were normal, respectively. Rev. 2.00 May. 08, 2008 Page 928 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2.6) The operating frequency is set to the FPEFEQ parameter and the user branch destination is set to the FUBRA parameter for initialization. 1. The current frequency of the CPU clock is set to the FPEFEQ parameter (general register R4). The settable range I of the FPEFEQ parameter is 32 to 40 MHz. When the frequency is set out of this range, an error is returned to the FPFR parameter of the initialization program and initialization is not performed. For details on the frequency setting, see the description in section 21.4.3 (2.1), Flash Programming/Erasing Frequency Parameter (FPEFEQ: General Register R4 of CPU). 2. The start address in the user branch destination is set to the (FUBRA: CPU general register R5) parameter. When the user branch processing is not required, 0 must be set to FUBRA. When the user branch is executed, the branch destination is executed in flash memory other than the one that is to be programmed. The area of the on-chip program that is downloaded cannot be set. The program processing must be returned from the user branch processing by the RTS instruction. See the description in section 21.4.3 (2.2), Flash User Branch Address Setting Parameter (FUBRA: General Register R5 of CPU). (2.7) Initialization When a programming program is downloaded, the initialization program is also downloaded to on-chip RAM. There is an entry point of the initialization program in the area from (download start address set by FTDAR) + 32 bytes. The subroutine is called and initialization is executed by using the following steps. MOV.L JSR NOP #DLTOP+32,R1 @R1 ; Set entry address to R1 ; Call initialization routine 1. The general registers other than R0 are saved in the initialization program. 2. R0 is a return value of the FPFR parameter. 3. Since the stack area is used in the initialization program, a stack area of 256 bytes or more must be reserved in RAM. 4. Interrupts can be accepted during the execution of the initialization program. However, the program storage area and stack area in on-chip RAM and register values must not be destroyed. Rev. 2.00 May. 08, 2008 Page 929 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2.8) The return value of the initialization program, FPFR (general register R0) is checked. (2.9) FKEY must be set to H'5A and the user MAT must be prepared for programming. (2.10) The parameter which is required for programming is set. The start address of the programming destination of the user MAT (FMPAR) is set to general register R5. The start address of the program data storage area (FMPDR) is set to general register R4. 1. FMPAR setting FMPAR specifies the programming destination start address. When an address other than one in the user MAT area is specified, even if the programming program is executed, programming is not executed and an error is returned to the return value parameter FPFR. Since the unit is 256 bytes, the lower eight bits (MOA7 to MOA0) must be in the 256-byte boundary of H'00. 2. FMPDR setting If the storage destination of the program data is flash memory, even when the program execution routine is executed, programming is not executed and an error is returned to the FPFR parameter. In this case, the program data must be transferred to on-chip RAM and then programming must be executed. (2.11) Programming There is an entry point of the programming program in the area from (download start address set by FTDAR) + 16 bytes of on-chip RAM. The subroutine is called and programming is executed by using the following steps. MOV.L JSR NOP #DLTOP+16,R1 @R1 ; Set entry address to R1 ; Call programming routine 1. The general registers other than R0 are saved in the programming program. 2. R0 is a return value of the FPFR parameter. 3. Since the stack area is used in the programming program, a stack area of maximum 128 bytes must be reserved in RAM.

Increment the programming destination address by 256 bytes and update the programming data pointer correctly. If an address which has already been programmed is written to again, not only will a programming error occur, but also flash memory will be damaged.

The procedure program must be executed in an area other than the user MAT to be erased. Especially the part where the SCO bit in FCCS is set to 1 for downloading must be executed in onchip RAM. The area that can be executed in the steps of the user procedure program (on-chip RAM, user MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program and Data for Programming. Rev. 2.00 May. 08, 2008 Page 932 of 1200 REJ09B0344-0200 Section 21 Flash Memory The frequency division ratio of an internal clock (I), a bus clock (B), and a peripheral clock (P) is specified as 4:4:4 by the frequency control register (FRQCR). For the downloaded on-chip program area, see the RAM map for programming/erasing in figure 21.10. A single divided block is erased by one erasing processing. For block divisions, see figure 21.4. To erase two or more blocks, update the erase block number and perform the erasing processing for each block. (3.1) Select the on-chip program to be downloaded and the download destination address Set the EPVB bit in FECS to 1. Several programming/erasing programs cannot be selected at one time. If several programs are set, download is not performed and a download error is returned to the source select error detect (SS) bit in the DPFR parameter. Specify the start address of the download destination by FTDAR. The procedures to be carried out after setting FKEY, e.g. download and initialization, are the same as those in the programming procedure. For details, see the description in section 21.5.2 (2), Programming Procedure in User Program Mode. (3.2) Set the FEBS parameter necessary for erasure Set the erase block number of the user MAT in the flash erase block select parameter (FEBS: general register R4). If a value other than an erase block number of the user MAT is set, no block is erased even though the erasing program is executed, and an error is returned to the return value parameter FPFR. (3.3) Erasure Similar to as in programming, there is an entry point of the erasing program in the area from (download start address set by FTDAR) + 16 bytes of on-chip RAM. The subroutine is called and erasing is executed by using the following steps. MOV.L JSR NOP #DLTOP+16,R1 @R1 ; Set entry address to R1 ; Call erasing routine 1. The general registers other than R0 are saved in the erasing program. 2. R0 is a return value of the FPFR parameter. 3. Since the stack area is used in the erasing program, a stack area of maximum 128 bytes must be reserved in RAM. Rev. 2.00 May. 08, 2008 Page 933 of 1200 REJ09B0344-0200 Section 21 Flash Memory (3.4) The return value in the erasing program, FPFR (general register R0) is checked. (3.5) Determine whether erasure of the necessary blocks has finished. If more than one block is to be erased, update the FEBS parameter and repeat steps (3.2) to (3.5). Blocks that have already been erased can be erased again. (3.6) After erasure finishes, clear FKEY and specify software protection. If this LSI is restarted by a power-on reset immediately after user MAT erasing has finished, secure a reset period (period of RES = 0) that is at least as long as the normal 100 s. (4) Erasing and Programming Procedure in User Program Mode By changing the on-chip RAM address of the download destination in FTDAR, the erasing program and programming program can be downloaded to separate on-chip RAM areas. Figure 21.13 shows an example of repetitively executing RAM emulation, erasing, and programming. Start procedure program Emulation/Erasing/Programming 1 Erasing program download Set FTDAR to H'00 (Specify H'FFF81000 as download destination) Erase relevant block (execute erasing program) Download erasing program Initialize erasing program Set FMPDR to H'FFF86000 to program relevant block (execute programming program) Programming program download Set FTDAR to H'02 (Specify H'FFF82000 as download destination) Confirm operation Download programming program Initialize programming program End? Yes End procedure program No 1 Figure 21.13 Sample Procedure of Repeating RAM Emulation, Erasing, and Programming (Overview) Rev. 2.00 May. 08, 2008 Page 934 of 1200 REJ09B0344-0200 Section 21 Flash Memory Download and initialization are performed only once at the beginning. In this kind of operation, note the following: 1. Be careful not to destroy on-chip RAM with overlapped settings. In addition to the erasing program area and programming program area, areas for the user procedure programs, work area, and stack area are reserved in on-chip RAM. Do not make settings that will overwrite data in these areas. 2. Be sure to initialize both the erasing program and programming program. Initialization by setting the FPEFEQ and FUBRA parameters must be performed for both the erasing program and the programming program. Initialization must be executed for both entry addresses: (download start address for erasing program) + 32 bytes (H'FFF81020 in this example) and (download start address for programming program) + 32 bytes (H'FFF82020 in this example). 21.5.3 User Boot Mode This LSI has user boot mode which is initiated with different mode pin settings than those in user program mode or boot mode. User boot mode is a user-arbitrary boot mode, unlike boot mode that uses the on-chip SCIF. Only the user MAT can be programmed/erased in user boot mode. Programming/erasing of the user boot MAT is only enabled in boot mode or programmer mode. (1) User Boot Mode Initiation For the mode pin settings to start up user boot mode, see table 21.1. When the reset start is executed in user boot mode, the check routine for flash-memory related registers runs on the on-chip RAM. NMI and all other interrupts cannot be accepted. Neither can the AUD be used in this period. This period is 100 s while operating at an internal frequency of 40 MHz. Next, processing starts from the execution start address of the reset vector in the user boot MAT. At this point, H'AA is set to the flash MAT select register (FMATS) because the execution MAT is the user boot MAT. Rev. 2.00 May. 08, 2008 Page 935 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2) User MAT Programming in User Boot Mode For programming the user MAT in user boot mode, additional processings made by setting FMATS are required: switching from user-boot-MAT selection state to user-MAT selection state, and switching back to user-boot-MAT selection state after programming completes. Figure 21.14 shows the procedure for programming the user MAT in user boot mode. Start programming procedure program Select on-chip program to be downloaded and set download destination by FTDAR 1 MAT switchover Set FKEY to H'A5 After clearing VBR, set SCO to 1 and execute download Set FMATS to value other than H'AA to select user MAT User-boot-MAT selection state Download Set FKEY to H'5A User-MAT selection state Clear FKEY to 0 Set parameter to R4 and R5 (FMPAR and FMPDR) DPFR=0 ?

Figure 21.14 Procedure for Programming User MAT in User Boot Mode Rev. 2.00 May. 08, 2008 Page 936 of 1200 REJ09B0344-0200 Section 21 Flash Memory The difference between the programming procedures in user program mode and user boot mode is whether the MAT is switched or not as shown in figure 21.14. In user boot mode, the user boot MAT can be seen in the flash memory space with the user MAT hidden in the background. The user MAT and user boot MAT are switched only while the user MAT is being programmed. Because the user boot MAT is hidden while the user MAT is being programmed, the procedure program must be located in an area other than flash memory. After programming finishes, switch the MATs again to return to the first state. MAT switchover is enabled by writing a specific value to FMATS. However note that while the MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not allowed until MAT switching is completely finished, and if an interrupt occurs, from which MAT the interrupt vector is read from is undetermined. Perform MAT switching in accordance with the description in section 21.7.1, Switching between User MAT and User Boot MAT. Except for MAT switching, the programming procedure is the same as that in user program mode. The area that can be executed in the steps of the user procedure program (on-chip RAM, user MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program and Data for Programming. Rev. 2.00 May. 08, 2008 Page 937 of 1200 REJ09B0344-0200 Section 21 Flash Memory (3) User MAT Erasing in User Boot Mode For erasing the user MAT in user boot mode, additional processings made by setting FMATS are required: switching from user-boot-MAT selection state to user-MAT selection state, and switching back to user-boot-MAT selection state after erasing completes. Figure 21.15 shows the procedure for erasing the user MAT in user boot mode. Start erasing procedure program Select on-chip program to be downloaded and set download destination by FTDAR 1 MAT switchover Set FKEY to H'A5 Set FMATS to value other than H'AA to select user MAT Download User-boot-MAT selection state After clearing VBR, set SCO to 1 and execute download Set FKEY to H'5A User-MAT selection state Clear FKEY to 0 Set FEBS parameter Programming JSR FTDAR setting+16 FPFR=0 ?

Figure 21.15 Procedure for Erasing User MAT in User Boot Mode Rev. 2.00 May. 08, 2008 Page 938 of 1200 REJ09B0344-0200 Section 21 Flash Memory The difference between the erasing procedures in user program mode and user boot mode depends on whether the MAT is switched or not as shown in figure 21.15. MAT switching is enabled by writing a specific value to FMATS. However note that while the MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not allowed until MAT switching is completed finished, and if an interrupt occurs, from which MAT the interrupt vector is read from is undetermined. Perform MAT switching in accordance with the description in section 21.7.1, Switching between User MAT and User Boot MAT. Except for MAT switching, the erasing procedure is the same as that in user program mode. The area that can be executed in the steps of the user procedure program (on-chip RAM, user MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program and Data for Programming. Rev. 2.00 May. 08, 2008 Page 939 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.6 Protection There are three kinds of flash memory program/erase protection: hardware, software, and error protection. 21.6.1 Hardware Protection Programming and erasing of flash memory is forcibly disabled or suspended by hardware protection. In this state, the downloading of an on-chip program and initialization of the flash memory are possible. However, an activated program for programming or erasure cannot program or erase locations in a user MAT, and the error in programming/erasing is reported in the FPFR parameter. Table 21.8 Hardware Protection Function to be Protected Item Description Download -- Programming/ Erasure FWE-pin protection The input of a low-level signal on the FWE pin clears the FWE bit of FCCS and the LSI enters a programming/erasing-protected state. Reset/standby protection * A power-on reset (including a power-on reset by the WDT) and entry to standby mode initializes the programming/erasing interface registers and the LSI enters a programming/erasing-protected state. Resetting by means of the RES pin after power is initially supplied will not make the LSI enter the reset state unless the RES pin is held low until oscillation has stabilized. In the case of a reset during operation, hold the RES pin low for the RES pulse width that is specified in the section on AC characteristics. If the LSI is reset during programming or erasure, data in the flash memory is not guaranteed. In this case, execute erasure and then execute programming again. * Rev. 2.00 May. 08, 2008 Page 940 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.6.2 Software Protection Software protection is set up in any of two ways: by disabling the downloading of on-chip programs for programming and erasing, and by means of a key code. Table 21.9 Software Protection Function to be Protected Item Protection by the SCO bit Description Clearing the SCO bit in FCCS disables downloading of the programming/erasing program, thus making the LSI enter a programming/erasing-protected state. Download Programming/ Erasure Protection by FKEY Downloading and programming/erasing are disabled unless the required key code is written in FKEY. Different key codes are used for downloading and for programming/erasing. 21.6.3 Error Protection Error protection is a mechanism for aborting programming or erasure when an error occurs, in the form of the microcontroller getting out of control during programming/erasing of the flash memory or operations that are not in accordance with the established procedures for programming/erasing. Aborting programming or erasure in such cases prevents damage to the flash memory due to excessive programming or erasing. If the microcontroller malfunctions during programming/erasing of the flash memory, the FLER bit in FCCS is set to 1 and the LSI enters the error protection state, thus aborting programming or erasure. Rev. 2.00 May. 08, 2008 Page 941 of 1200 REJ09B0344-0200 Section 21 Flash Memory The FLER bit is set to 1 in the following conditions: * When the relevant bank area of flash memory is read during programming/erasing (including a vector read or an instruction fetch) * When a SLEEP instruction (including software standby mode) is executed during programming/erasing Error protection is cancelled (FLER bit is cleared) only by a power-on reset. Note that the reset signal should only be released after providing a reset input over a period longer than the normal 100 s. Since high voltages are applied during programming/erasing of the flash memory, some voltage may still remain even after the error protection state has been entered. For this reason, it is necessary to reduce the risk of damage to the flash memory by extending the reset period so that the charge is released. The state-transition diagram in figure 21.16 shows transitions to and from the error protection state. Program mode Erase mode Read disabled Programming/erasing enabled FLER=0 RES = 0 Er Reset (Hardware protection) Read enabled Programming/erasing disabled FLER=0 ror (S Error occurred oc cu oft rred wa re sta n S RE =0 RES=0 Programming/erasing interface register is in its initial state. db y) Error protection mode (Software standby) Error protection mode Read enabled Programming/erasing disabled FLER=1 Software standby mode Read disabled Cancel Programming/erasing disabled software standby mode FLER=1 Programming/erasing interface register is in its initial state. Figure 21.16 Transitions to and from Error Protection State Rev. 2.00 May. 08, 2008 Page 942 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.7 21.7.1 Usage Notes Switching between User MAT and User Boot MAT It is possible to switch between the user MAT and user boot MAT. However, the following procedure is required because these MATs are allocated to address 0. (Switching to the user boot MAT disables programming and erasing. Programming of the user boot MAT must take place in boot mode or programmer mode.) 1. MAT switching by FMATS should always be executed from the on-chip RAM. The SH microcontroller prefetches execution instructions. Therefore, a switchover during program execution in the user MAT causes an instruction code in the user MAT to be prefetched or an instruction in the newly selected user boot MAT to be prefetched, thus resulting in unstable operation. 2. To ensure that the MAT that has been switched to is accessible, execute thirty-two NOP instructions in on-chip RAM immediately after writing to FMATS of on-chip RAM (this prevents access to the flash memory during MAT switching). 3. If an interrupt occurs during switching, there is no guarantee of which memory MAT is being accessed. Always mask the maskable interrupts before switching MATs. In addition, configuring the system so that NMI interrupts do not occur during MAT switching is recommended. 4. After the MATs have been switched, take care because the interrupt vector table will also have been switched. If the same interrupt processings are to be executed before and after MAT switching or interrupt requests cannot be disabled, transfer the interrupt processing routine to on-chip RAM, and use the VBR setting to place the interrupt vector table in on chip RAM. In this case, make sure the VBR setting change does not conflict with the interrupt occurrence. 5. Memory sizes of the user MAT and user boot MAT are different. When accessing the user boot MAT, do not access addresses exceeding the 12-kbyte memory space. If access goes beyond the 12-kbyte space, the values read are undefined.

(2) Write a value other than H'AA to FMATS. (3) Execute thirty-two NOP instructions before accessing the user MAT. Figure 21.17 Switching between User MAT and User Boot MAT 21.7.2 (1) (a) Interrupts during Programming/Erasing Download of On-Chip Program VBR Setting Change Before downloading the on-chip program, VBR must be set to H'80000000. If VBR is set to a value other than H'80000000, the interrupt vector table is placed in the user MAT (FMATS is not H'AA) or the user boot MAT (FMATS is H'AA) on setting H'80000000 to VBR. When VBR setting change conflicts with interrupt occurrence, whether the vector table before or after VBR is changed is referenced may cause an error. Therefore, for cases where VBR setting change may conflict with interrupt occurrence, prepare a vector table to be referenced when VBR is H'00000000 (initial value) at the start of the user MAT or user boot MAT. (b) SCO Download Request and Interrupt Request Download of the on-chip programming/erasing program that is initiated by setting the SCO bit in FCCS to 1 generates a particular interrupt processing accompanied by MAT switchover. Operation when the SCO download request and interrupt request conflicts is described below. 1. Contention between SCO download request and interrupt request Figure 21.18 shows the timing of contention between execution of the instruction that sets the SCO bit in FCCS to 1 and interrupt acceptance.

Rev. 2.00 May. 08, 2008 Page 945 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2) Interrupts during Programming/Erasing Though an interrupt processing can be executed at realtime during programming/erasing of the downloaded on-chip program, the following limitations and notes are applied. 1. When flash memory is being programmed or erased, both the user MAT and user boot MAT cannot be accessed. Prepare the interrupt vector table and interrupt processing routine in on-chip RAM or external memory. Make sure the flash memory being programmed or erased is not accessed by the interrupt processing routine. If flash memory is read, the read values are not guaranteed. If the relevant bank in flash memory that is being programmed or erased is accessed, the error protection state is entered, and programming or erasing is aborted. If a bank other than the relevant bank is accessed, the error protection state is not entered but the read values are not guaranteed. 2. Do not rewrite the program data specified by the FMPDR parameter. If new program data is to provided by the interrupt processing, temporarily save the new program data in another area. After confirming the completion of programming, save the new program data in the area specified by FMPDR or change the setting in FMPDR to indicated the other area in which the new program data was temporarily saved. 3. Make sure the interrupt processing routine does not rewrite the contents of the flashmemory related registers or data in the downloaded on-chip program area. During the interrupt processing, do not simultaneously perform download of the on-chip program by an SCO request or programming/erasing. 4. At the beginning of the interrupt processing routine, save the CPU register contents. Before returning from the interrupt processing, write the saved contents in the CPU registers again. 5. When a transition is made to sleep mode or software standby mode in the interrupt processing routine, the error protection state is entered and programming/erasing is aborted. If a transition is made to the reset state, the reset signal should only be released after providing a reset input over a period longer than the normal 100 s to reduce the damage to flash memory. 21.7.3 (1) Other Notes Download Time of On-Chip Program The programming program that includes the initialization routine and the erasing program that includes the initialization routine are each 3 kbytes or less. Accordingly, when the CPU clock frequency is 40 MHz, the download for each program takes approximately 10 ms at maximum. Rev. 2.00 May. 08, 2008 Page 946 of 1200 REJ09B0344-0200 Section 21 Flash Memory (2) User Branch Processing Intervals The intervals for executing the user branch processing differs in programming and erasing. The processing phase also differs. Table 21.10 lists the maximum intervals for initiating the user branch processing when the CPU clock frequency is 40 MHz. Table 21.10 Initiation Intervals of User Branch Processing Processing Name Programming Erasing Note: * Reference value Maximum Interval Approximately 2 ms* Approximately 15 ms* However, when operation is done with CPU clock of 40 MHz, maximum values of the time until first user branch processing are as shown in table 21.11. Table 21.11 Initial User Branch Processing Time Processing Name Programming Erasing Note: * Reference value Maximum Approximately 2 ms* Approximately 15 ms* (3) Write to Flash-Memory Related Registers by DMAC While an instruction in on-chip RAM is being executed, the DMAC can write to the SCO bit in FCCS that is used for a download request or FMATS that is used for MAT switching. Make sure that these registers are not accidentally written to, otherwise an on-chip program may be downloaded and destroy RAM or a MAT switchover may occur and the CPU get out of control. (4) State in which Interrupts are Ignored In the following modes or period, interrupt requests are ignored; they are not executed and the interrupt sources are not retained. * Boot mode * Programmer mode Rev. 2.00 May. 08, 2008 Page 947 of 1200 REJ09B0344-0200 Section 21 Flash Memory (5) Compatibility with Programming/Erasing Program of Conventional F-ZTAT SH Microcontroller A programming/erasing program for flash memory used in the conventional F-ZTAT SH microcontroller which does not support download of the on-chip program by a SCO transfer request cannot run in this LSI. Be sure to download the on-chip program to execute programming/erasing of flash memory in this LSI. (6) Monitoring Runaway by WDT Unlike the conventional F-ZTAT SH microcontroller, no countermeasures are available for a runaway by WDT during programming/erasing by the downloaded on-chip program. Prepare countermeasures (e.g. use of the user branch routine and periodic timer interrupts) for WDT while taking the programming/erasing time into consideration as required. (7) The Operating Frequency in On-Board Programming Mode The frequency control register (FRQCR) should be set as follows in the erasing and programming procedure, described in section 21.5, On-Board Programming Mode. * Specify (I: B: P) = (4: 4: 4) as the frequency division ratios of internal clocks. When the input clock is 10 MHz, (I: B: P) = (40 MHz: 40 MHz: 40MHz) When the input clock is 8 MHz, (I: B: P) = (32 MHz: 32 MHz: 32MHz) * The following shows the frequency control register (FRQCR) values where (I: B: P) = (4: 4: 4) as the frequency division ratios of internal clocks. H'1000* H'1111* H'1333* Note: * The CKOEN bit (bit 12) can be specified as either 0 or1. (8) Programming the User MAT in User Program Mode This LSI does not allow transitions from single chip mode to user program mode. Therefore, in order to program the user MAT in user program mode, be sure to activate the LSI in MCU extension mode 2 rather than in single chip mode. Rev. 2.00 May. 08, 2008 Page 948 of 1200 REJ09B0344-0200 Section 21 Flash Memory 21.8 21.8.1 Supplementary Information Specifications of the Standard Serial Communications Interface in Boot Mode The boot program activated in boot mode communicates with the host via the on-chip SCI of the LSI. The specifications of the serial communications interface between the host and the boot program are described below. (1) States of Boot Program The boot program has three states. 1. Bit-rate matching state In this state, the boot program adjusts the bit rate to match that of the host. When the chip starts up in boot mode, the boot program is activated and enters the bit-rate matching state, in which it receives commands from the host and adjusts the bit rate accordingly. After bit-rate matching is complete, the boot program proceeds to the inquiry-and-selection state. 2. Inquiry-and-selection state In this state, the boot program responds to inquiry commands from the host. The device, clock mode, and bit rate are selected in this state. After making these selections, the boot program enters the programming/erasure state in response to the transition-to-programming/erasure state command. The boot program transfers the erasure program to RAM and executes erasure of the user MAT and user boot MAT before it enters the programming/erasure state. 3. Programming/erasure state In this state, programming/erasure are executed. The boot program transfers the program for programming/erasure to RAM in line with the command received from the host and executes programming/erasure. It also performs sum checking and blank checking as directed by the respective commands. Figure 21.19 shows the flow of processing by the boot program.

Input frequency The value of the received input frequency is checked to see if it is within the range of the minimum and maximum values of input frequency for the selected clock mode of the selected device. A value outside the range generates an input frequency error. 2. Multiplier The value of the received multiplier is checked to see if it matches a multiplier or divisor that is available for the selected clock mode of the selected device. A value that does not match an available ratio generates a frequency multiplier error. 3. Operating frequency The operating frequency is calculated from the received input frequency and the frequency multiplier or divisor. The input frequency is the frequency of the clock signal supplied to the LSI, while the operating frequency is the frequency at which the LSI is actually driven. The following formulae are used for this calculation. Operating frequency = input frequency x multiplier, or Operating frequency = input frequency / divisor The calculated operating frequency is checked to see if it is within the range of the minimum and maximum values of the operating frequency for the selected clock mode of the selected device. A value outside the range generates an operating frequency error. 4. Bit rate From the peripheral operating frequency (P) and the bit rate (B), the value (= n) of the clock select bits (CKS) in the serial mode register (SCSMR) and the value (= N) of the bit rate register (SCBRR) are calculated, after which the error in the bit rate is calculated. This error is checked to see if it is smaller than 4%. A result greater than or equal to 4% generates a bit rate selection error. The following formula is use to calculate the error. Error (%) = [ P x 106 ]-1 (N + 1) x B x 64 x 22n-1 x 100 Rev. 2.00 May. 08, 2008 Page 963 of 1200 REJ09B0344-0200 Section 21 Flash Memory When the new bit rate is selectable, the boot program returns an ACK code to the host and then makes the register setting to select the new bit rate.

On completion of this erasure, the boot program returns the ACK code and enters the programming/erasure state. Before sending the programming selection command and data for programming, the host must select the device, clock mode, and new bit rate for the LSI by issuing the device selection command, clock-mode selection command, new-bit-rate selection command, and then initiate the transition to the programming/erasure state by sending the corresponding command to the boot program.

Firstly, the host issues the programming-selection command to select the MAT to be programmed. Two programming-selection commands are provided for the selection of either of the two target areas. 1. Selection of user boot MAT programming 2. Selection of user MAT programming Next, the host issues a 256-byte programming command. 256 bytes of data for programming by the method selected by the preceding programming selection command are expected to follow the command. To program more than 256 bytes, repeatedly issue 256-byte programming commands. To terminate programming, the host should send another 256-byte programming command with the address H'FFFFFFFF. On completion of programming, the boot program waits for the next programming/erasure selection command. To then program the other MAT, start by sending the programming select command.

Firstly, the host sends the erasure selection command to select erasure; after that, it sends a block erasure command to actually erase a specific block. To erase multiple blocks, send further block erasure commands. To terminate erasure, the host should send a block erasure command with the block number H'FF. After this, the boot program waits for the next programming/erasure selection command. The sequence of erasure by the erasure selection command and block erasure command is shown in figure 21.24.

However, the procedure programs and data can be stored in and executed from other areas (e.g. external address space) as long as the following conditions are satisfied. 1. The on-chip programming/erasing program is downloaded from the address set by FTDAR in on-chip RAM, therefore, this area is not available for use. 2. The on-chip programming/erasing program will use 128 bytes or more as a stack. Make sure this area is reserved. 3. Since download by setting the SCO bit to 1 will cause the MATs to be switched, it should be executed in on-chip RAM. 4. The flash memory is accessible until the start of programming or erasing, that is, until the result of downloading has been decided. Rev. 2.00 May. 08, 2008 Page 979 of 1200 REJ09B0344-0200 Section 21 Flash Memory 5. The flash memory is not accessible during programming/erasing operations. Therefore, the programming/erasing program must be downloaded to on-chip RAM in advance. Areas for executing each procedure program for initiating programming/erasing, the user program at the user branch destination for programming/erasing, the interrupt vector table, and the interrupt processing routine must be located in on-chip memory other than flash memory or the external address space. 6. After programming/erasing, access to flash memory is inhibited until FKEY is cleared. A reset state (RES = 0) for more than at least 100 s must be taken when the LSI mode is changed to reset on completion of a programming/erasing operation. Transitions to the reset state during programming/erasing are inhibited. When the reset signal is accidentally input to the LSI, a longer period in the reset state than usual (100 s) is needed before the reset signal is released. 7. Switching of the MATs by FMATS is needed for programming/erasing of the user MAT in user boot mode. The program which switches the MATs should be executed from the on-chip RAM. For details, see section 21.7.1, Switching between User MAT and User Boot MAT. Please make sure you know which MAT is selected when switching the MATs. 8. When the program data storage area indicated by the FMPDR parameter in the programming processing is within the flash memory area, an error will occur. Therefore, temporarily transfer the program data to on-chip RAM to change the address set in FMPDR to an address other than flash memory. Based on these conditions, tables 21.16 and 21.17 show the areas in which the program data can be stored and executed according to the operation type and mode.

Although each access is completed correctly, this kind of conflict degrades the memory access speed. Therefore, it is advisable to provide software measures to prevent such conflicts as far as possible. For example, no conflict will arise if different memory or pages are accessed by each bus. 22.2.2 RAME and RAMWE Bits Before disabling memory operation or write access through the RAME or RAMWE bit, be sure to read from any address and then write to the same address in each page; otherwise, the last written data in each page may not be actually written to the RAM. For setting the RAME and RAMWE bits, see section 23.3.5, System Control Register 1 (SYSCR1), and section 23.3.6, System Control Register 2 (SYSCR2).

There are two types of reset: power-on reset and manual reset. In a power-on reset, all the ongoing processing is halted and any unprocessed events are canceled, and the reset processing starts immediately. On the other hand, a manual reset does not interrupt processing to retain external memory data. Conditions for generating a power-on reset or manual reset are as follows: (1) 1. 2. Power-on Reset A low level is input to the RES pin. The watchdog timer (WDT) starts counting with the WT/IT bit in WTCSR set to 1 and with the RSTS bit in WRCSR set to 0 while the RSRE bit in WRCSR is 1, and the counter overflows. The H-UDI reset is generated (for details on the H-UDI reset, see section 24, User Debugging Interface (H-UDI)). Manual Reset A low level is input to the MRES pin. The WDT starts counting with the WT/IT bit in WTCSR set to 1 and with the RSTS bit in WRCSR set to 1 while the RSRE bit in WRCSR is 1, and the counter overflows. 3. (2) 1. 2.

SYSCR1 is initialized to H'FF by a power-on reset but retains its previous value by a manual reset or in software standby mode. Only byte access is possible. When an RAME bit is set to 1, the corresponding on-chip RAM area is enabled. When an RAME bit is cleared to 0, the corresponding on-chip RAM area cannot be accessed. In this case, an undefined value is returned when reading data or fetching an instruction from the on-chip RAM, and writing to the on-chip RAM is ignored. The initial value of an RAME bit is 1. Note that when clearing the RAME bit to 0 to disable the on-chip RAM, be sure to execute an instruction to read from or write to the same arbitrary address in each page before setting the RAME bit. If such an instruction is not executed, the data last written to each page may not be written to the on-chip RAM. Furthermore, an instruction to access the on-chip RAM should not be located immediately after the instruction to write to SYSCR1. If an on-chip RAM access instruction is set, normal access is not guaranteed. To enable the on-chip RAM by setting the RAME bit to 1, place an instruction to read data from SYSCR1 immediately after an instruction to write to SYSCR1. If an instruction to access the onchip RAM is placed immediately after the instruction to write to SYSCR1, normal access is not guaranteed.

SYSCR2 is initialized to H'FF by a power-on reset but retains its previous value by a manual reset or in software standby mode. Only byte access is valid. When an RAMWE bit is set to 1, the corresponding on-chip RAM area is enabled. When an RAMWE bit is cleared to 0, the corresponding on-chip RAM area cannot be written to. In this case, writing to the on-chip RAM is ignored. The initial value of an RAMWE bit is 1. Note that when clearing the RAMWE bit to 0 to disable the on-chip RAM, be sure to execute an instruction to read from or write to the same arbitrary address in each page before setting the RAMWE bit. If such an instruction is not executed, the data last written to each page may not be written to the on-chip RAM. Furthermore, an instruction to access the on-chip RAM should not be located immediately after the instruction to write to SYSCR2. If an on-chip RAM access instruction is set, normal access is not guaranteed. To enable the on-chip RAM by setting the RAMWE bit to 1, locate an instruction to read data from SYSCR2 immediately after an instruction to write to SYSCR2. If an instruction to access the on-chip RAM is located immediately after the instruction to write to SYSCR2, normal access is not guaranteed.

Although the CPU halts immediately after executing the SLEEP instruction, the contents of its internal registers remain unchanged. The on-chip modules continue to run in sleep mode. Clock pulses are output continuously on the CK pin. (2) Canceling Sleep Mode Sleep mode is canceled by an interrupt (NMI, IRQ, and on-chip peripheral module), DMA address error, or reset (manual reset or power-on reset). * Canceling with an interrupt When an NMI, IRQ, or on-chip peripheral module interrupt occurs, sleep mode is canceled and interrupt exception handling is executed. When the priority level of the generated interrupt is equal to or lower than the interrupt mask level that is set in the status register (SR) of the CPU, or the interrupt by the on-chip peripheral module is disabled on the module side, the interrupt request is not accepted and sleep mode is not canceled. * Canceling with a DMA address error When a DMA address error occurs, sleep mode is canceled and DMA address error exception handling is executed. * Canceling with a reset Sleep mode is canceled by a power-on reset or a manual reset. 23.4.2 (1) Software Standby Mode Transition to Software Standby Mode The LSI switches from a program execution state to software standby mode by executing the SLEEP instruction when the STBY bit in STBCR is 1. In software standby mode, not only the CPU but also the clock and on-chip peripheral modules halt. The clock output from the CK pin also halts. The contents of the CPU remain unchanged. Some registers of on-chip peripheral modules are, however, initialized. Table 23.4 shows the states of peripheral module registers in software standby mode. Rev. 2.00 May. 08, 2008 Page 1005 of 1200 REJ09B0344-0200 Section 23 Power-Down Modes The CPU takes one cycle to finish writing to STBCR, and then executes processing for the next instruction. However, it takes one or more cycles to actually write. Therefore, execute a SLEEP instruction after reading STBCR to have the values written to STBCR by the CPU to be definitely reflected in the SLEEP instruction. Table 23.4 Register States in Software Standby Mode Module Name Interrupt controller (INTC) Clock pulse generator (CPG) User break controller (UBC) Bus state controller (BSC) A/D converter (ADC) I/O port User debugging interface (H-UDI) Serial communication interface with FIFO (SCIF) Direct memory access controller (DMAC) Multi-function timer pulse unit 2 (MTU2) Multi-function timer pulse unit 2S (MTU2S) Port output enable 2 (POE2) Compare match timer (CMT) I C bus interface 3 (IIC3) D/A converter (DAC) 2 Initialized Registers All registers All registers BC2 and BC0 bits in ICMR register Registers Whose Content is Retained All registers All registers All registers All registers All registers All registers All registers All registers All registers All registers All registers Other than BC[2:0] bits in ICMR All registers The procedure for switching to software standby mode is as follows: 1. Clear the TME bit in the WDT's timer control register (WTCSR) to 0 to stop the WDT. 2. Set the WDT's timer counter (WTCNT) to 0 and the CKS[2:0] bits in WTCSR to appropriate values to secure the specified oscillation settling time. 3. After setting the STBY bit in STBCR to 1, read STBCR. Then, execute a SLEEP instruction. Rev. 2.00 May. 08, 2008 Page 1006 of 1200 REJ09B0344-0200 Section 23 Power-Down Modes (2) Exit from Software Standby Mode Software standby mode is exited by interrupts (NMI or IRQ) or a reset (manual reset or power-on reset). (a) Exit from Software Standby by an Interrupt When the falling edge or rising edge of the NMI pin (selected by the NMI edge select bit (NMIE) in interrupt control register 0 (ICR0) of the interrupt controller (INTC)) or the falling edge or rising edge of an IRQ pin (IRQ7 to IRQ0) (selected by the IRQn sense select bits (IRQn1S and IRQn0S) in interrupt control register 1 (ICR1) of the interrupt controller (INTC)) is detected, clock oscillation is started. This clock pulse is supplied only to the oscillation settling counter (WDT) used to count the oscillation settling time. After the elapse of the time set in the clock select bits (CKS[2:0]) in the watchdog timer control/status register (WTCSR) of the WDT before the transition to software standby mode, the WDT overflow occurs. Since this overflow indicates that the clock has been stabilized, the clock pulse will be supplied to the entire chip after this overflow. Software standby mode is cleared and NMI interrupt exception handling (IRQ interrupt exception handling in the case of IRRQ) starts. When canceling software standby mode by the NMI interrupt or IRQ interrupt, set the CKS[2:0] bits so that the WDT overflow period will be equal to or longer than the oscillation settling time. The clock output phase of the CK pin may be unstable immediately after detecting an interrupt and until software standby mode is canceled. When software standby mode is canceled by the falling edge of the NMI pin, the NMI pin should be high when the CPU enters software standby mode (when the clock pulse stops) and should be low when the CPU returns from software standby mode (when the clock is initiated after the oscillation settling). When software standby mode is canceled by the rising edge of the NMI pin, the NMI pin should be low when the CPU enters software standby mode (when the clock pulse stops) and should be high when the CPU returns from software standby mode (when the clock is initiated after the oscillation settling) (This is the same with the IRQ pin.) (b) Exit from Software Standby by a Reset When the RES or MRES pin is driven low, this LSI enters the power-on reset or manual reset state, and software standby mode is exited. Keep the RES or MRES pin low until the clock oscillation settles. Internal clock pulses are output continuously on the CK pin. Rev. 2.00 May. 08, 2008 Page 1007 of 1200 REJ09B0344-0200 Section 23 Power-Down Modes 23.4.3 Software Standby Mode Application Example This example describes a transition to software standby mode on the falling edge of the NMI signal, and cancellation on the rising edge of the NMI signal. The timing is shown in figure 23.1. When the NMI pin is changed from high to low level while the NMI edge select bit (NMIE) in ICR is set to 0 (falling edge detection), the NMI interrupt is accepted. When the NMIE bit is set to 1 (rising edge detection) by the NMI exception service routine, the STBY bit in STBCR is set to 1, and a SLEEP instruction is executed, software standby mode is entered. Thereafter, software standby mode is canceled when the NMI pin is changed from low to high level.

This function can be used to reduce the power consumption in normal mode and sleep mode. Disable a module before placing it in module standby mode. In addition, do not access the module's registers while it is in the module standby state. The register states are the same as those in software standby mode. For details of register states, see table 23.4. However, the states of the CMT and DAC registers are exceptional. In the CMT, all registers are initialized in software standby mode, but retain their previous values in module standby mode. In the DAC, all registers retain their previous values in software standby mode, but are initialized in module standby mode. (2) Canceling Module Standby Function The module standby function can be canceled by clearing the MSTP bits to 0, or by a power-on reset (only possible for H-UDI, UBC, and DMAC). When taking a module out of the module standby state by clearing the corresponding MSTP bit to 0, read the MSTP bit to confirm that it has been cleared to 0.

The H-UDI in this LSI is used for emulator connection. Refer to the emulator manual for the method of connecting the emulator. Figure 24.1 shows a block diagram of the H-UDI.

The state of the TAP control circuit is determined by changing this signal in synchronization with TCK. For the protocol, see figure 24.2. Input is accepted asynchronously with respect to TCK, and when low, the H-UDI is reset. TRST must be low for a constant period when power is turned on regardless of using the H-UDI function. See section 24.4.2, Reset Configuration, for more information. Data transfer to the H-UDI is executed by changing this signal in synchronization with TCK. Data read from the H-UDI is executed by reading this pin in synchronization with TCK. The initial value of the data output timing is the TCK falling edge. This can be changed to the TCK rising edge by inputting the TDO change timing switch command to SDIR. See section 24.4.3, TDO Output Timing, for more information. If a low level is input at the ASEMD pin while the RES pin is asserted, ASE mode is entered; if a high level is input, normal mode is entered. In ASE mode, dedicated emulator function can be used. The input level at the ASEMD pin should be held for at least one cycle after RES negation.

In this state, the CPU does not start up. When TRST is driven high, H-UDI operation is enabled, but the CPU does not start up. The reset hold state is cancelled by a power-on reset. 24.4.3 TDO Output Timing The initial value of the TDO change timing is to perform data output from the TDO pin on the TCK falling edge. However, setting a TDO change timing switch command in SDIR via the HUDI pin and passing the Update-IR state synchronizes the TDO change timing to the TCK rising edge. Thereafter the TDO change timing cannot be changed unless a power-on reset that asserts the TRST pin simultaneously is performed.

An H-UDI reset is of the same kind as a power-on reset. An H-UDI reset is released by setting an H-UDI reset negate command. The required time between the H-UDI reset assert command and H-UDI reset negate command is the same as time for keeping the RES pin low to apply a power-on reset.

An H-UDI interrupt is a general exception/interrupt operation, resulting in fetching the exception service routine start address from the exception handling vector table, jumping to that address, and starting program execution from that address. This interrupt request has a fixed priority level of 15. H-UDI interrupts are accepted in sleep mode, but not in software standby mode.

An H-UDI command, once set, will not be modified as long as another command is not set again from the H-UDI. If the same command is to be set continuously, the command must be set after a command (BYPASS mode, etc.) that does not affect chip operations is once set. 2. In software standby mode and H-UDI module standby state, all of the functions in the H-UDI cannot be used. To retain the TAP status before and after standby mode, keep TCK high before entering standby mode.

Register Bits * Bit configurations of the registers are described in the same order as the Register Addresses (by functional module, in order of the corresponding section numbers). * Reserved bits are indicated by -- in the bit name. * No entry in the bit-name column indicates that the whole register is allocated as a counter or for holding data. 3. Register States in Each Operating Mode * Register states are described in the same order as the Register Addresses (by functional module, in order of the corresponding section numbers). * For the initial state of each bit, refer to the description of the register in the corresponding section. * The register states described are for the basic operating modes. If there is a specific reset for an on-chip peripheral module, refer to the section on that on-chip peripheral module. 4. Notes when Writing to the On-Chip Peripheral Modules * To access an on-chip module register, two or more peripheral module clock (Pf) cycles are required. Care must be taken in system design. When the CPU writes data to the internal peripheral registers, the CPU performs the succeeding instructions without waiting for the completion of writing to registers. For example, a case is described here in which the system is transferring to the software standby mode for power savings. To make this transition, the SLEEP instruction must be performed after setting the STBY bit in the STBCR register to 1. However a dummy read of the STBCR register is required before executing the SLEEP instruction. If a dummy read is omitted, the CPU executes the SLEEP instruction before the STBY bit is set to 1, thus the system enters sleep mode not software standby mode. A dummy read of the STBCR register is indispensable to complete writing to the STBY bit. To reflect the change by internal peripheral registers while performing the succeeding instructions, execute a dummy read of registers to which write instruction is given and then perform the succeeding instructions.

AVcc (5.0-V power supply) AVcc Min. voltage (4.5 V) VccQ (3.3-V power supply) VccQ Min. voltage (3.0 V) Vcc, PLLVcc (1.5-V power supply) Vcc, PLLVcc Min. voltage (1.4 V) GND tunc Pins status undefined Normal operation period tunc Pins status undefined Figure 27.1 Power-on/Power-off Sequence Table 27.2 Recommended Time for Power-on/Power-off Sequence Item Undefined time Note: Symbol tunc Maximum Allowance Value 100 Unit ms VccQ Vcc = PLLVcc is recommended. Either VccQ, Vcc, or PLLVcc power supply can be turned on or off first, though, an undefined period appears until Vcc rises to the Min. voltage or after Vcc passes the Min. voltage. During these periods, pin or internal states become undefined. Design the system so that such undefined states do not cause a system malfunction. To avoid an increase in the current consumption during the undefined period at power-on, it is recommended that VccQ, Vcc, and PLLVcc be turned on simultaneously. This undefined period can be eliminated by turning on the power supplies in the order shown in figure 27.2. Rev. 2.00 May. 08, 2008 Page 1082 of 1200 REJ09B0344-0200 Section 27 Electrical Characteristics AVcc (5.0-V power supply) AVcc Min. voltage (4.5 V) VccQ (3.3-V power supply) VccQ Min. voltage (3.0 V) Vcc, PLLVcc (1.5-V power supply) Vcc, PLLVcc Min. (1.4 V) GND Pin initial status Normal operation period Figure 27.2 Power-On Sequence Notes: 1. AVcc = AVREF > Vcc = PLLVcc is recommended. Either AVcc or VccQ power supply can be turned on or off first. However, note that the equation AVcc 0.3 V = AVREF should always be true. Using the LSI under the following conditions may result in decreased reliability or permanent damage to the LSI. AVREF > AVcc 0.3 V 2. To prevent the pin and internal states from being undefined, VccQ and AVcc should be kept GND voltage level (0 V) and they should not be placed in floating state until Vcc reaches the Min. voltage. In addition, the RES pin should be input low to place poweron reset state. In this case, care must be taken for the power consumption increase caused by sink current because each pin is placed in low-impedance state until VccQ reaches the Min. voltage.

The CPU operates as follows: Note: * This is the case in which an address error was caused by data read or write. When an address error is caused by an instruction fetch, and if the bus cycle in which the address error occurred does not end by step 3 above, the CPU restarts the address error exception handling until the bus cycle ends. 6.3.4 IRQ Interrupt Request Register (IRQRR) 110 Note added Note: * Only 0 can be written to clear the flag after 1 is read.

While this setting is valid, data is not transferred from the buffer register outside the buffer transfer-enabled period. There are two types of timing in which data is transferred from the buffer register to the temporary register or to general register, depending on the buffer register modification timing after an interrupt occurrence. Note that the buffer transfer-enabled period depends on the T3AEN and T4VEN bit settings in the timer interrupt skipping set register (TITCR).

In this case, the values of TCNT_1 = H'FFF1 and TCNT_2 = H'0000 should be transferred to TGRA_1 and TGRA_2 or to TGRB_1 and TGRB_2, but the values of TCNT_1 = H'FFF0 and TCNT_2 = H'0000 are erroneously transferred. The MTU2 additionally supports the function that can capture TCNT_1 and TCNT_2 simultaneously via a single input capture input. This function allows 32-bit counter fetches without TCNT_1 and TCNT_2 capture timing deviation.

Note: * Since SCFTDR is a 16-byte FIFO register, the maximum quantity of data that can be written when TDFE is 1 is "16 minus the specified transmission trigger number". If an attempt is made to write additional data, the data is ignored. The quantity of data in SCFTDR is indicated by the upper 8 bits of SCFDR. 15.3.8 Bit Rate Register 687 (SCBRR) Description amended The CPU can always read and write to SCBRR.

27.2 Recommended Time for Power-on/Power-off Sequence 1082 Note amended Note: VCCQ VCC = PLLVCC is recommended. Either VCCQ, VCC, or PLLVCC power supply can be turned on or off first, though, an undefined period appears until VCC rises to the Min. voltage or after VCC passes the Min. voltage. During these periods, pin or internal states become undefined. Design the system so that such undefined states do not cause a system malfunction. To avoid an increase in the current consumption during the undefined period at power-on, it is recommended that VCCQ, VCC, and PLLVCC be turned on simultaneously. This undefined period can be eliminated by turning on the power supplies in the order shown in figure 27.2.
