Fig. 1 AMC instruction execution example ALU (2) Register A and carry flag Register A is a 4-bit register used for arithmetic, transfer, exchange, and I/O operation. Carry flag CY is a 1-bit flag that is set to "1" when there is a carry with the AMC instruction (Figure 1). It is unchanged with both A n instruction and AM instruction. The value of A0 is stored in carry flag CY with the RAR instruction (Figure 2). Carry flag CY can be set to "1" with the SC instruction and cleared to "0" with the RC instruction. CY A3 A2 A1 A0 (3) Registers B and E Register B is a 4-bit register used for temporary storage of 4-bit data, and for 8-bit data transfer together with register A. Register E is an 8-bit register. It can be used for 8-bit data transfer with register B used as the high-order 4 bits and register A as the low-order 4 bits (Figure 3). Register E is undefined after system is released from reset and returned from the RAM back-up. Accordingly, set the initial value. A0 CY A3 A2 A1 Fig. 2 RAR instruction execution example Register B TAB instruction Register A B3 B2 B1 B0 A3 A2 A1 A0 (4) Register D Register D is a 3-bit register. It is used to store a 7-bit ROM address together with register A and is used as a pointer within the specified page when the TABP p, BLA p, or BMLA p instruction is executed (Figure 4). Also, when the TABP p instruction is executed at UPTF flag = "1", the high-order 2 bits of ROM reference data is stored to the low-order 2 bits of register D, the high-order 1 bit of register D is "0". When the TABP p instruction is executed at UPTF flag = "0", the contents of register D remains unchanged. The UPTF flag is set to "1" with the SUPT instruction and cleared to "0" with the RUPT instruction. The initial value of UPTF flag is "0". Register D is undefined after system is released from reset and returned from the RAM back-up. Accordingly, set the initial value.

Stack registers (SKs) are eight identical registers, so that subroutines can be nested up to 8 levels. However, one of stack registers is used respectively when using an interrupt service routine and when executing a table reference instruction. Accordingly, be careful not to over the stack when performing these operations together. The contents of registers SKs are destroyed when 8 levels are exceeded. The register SK nesting level is pointed automatically by 3-bit stack pointer (SP). The contents of the stack pointer (SP) can be transferred to register A with the TASP instruction. Figure 5 shows the stack registers (SKs) structure. Figure 6 shows the example of operation at subroutine call. Program counter (PC) Executing BM instruction SK0 SK1 SK2 SK3 SK4 SK5 SK6 SK7 Executing RT instruction (SP) = 0 (SP) = 1 (SP) = 2 (SP) = 3 (SP) = 4 (SP) = 5 (SP) = 6 (SP) = 7 (6) Interrupt stack register (SDP) Interrupt stack register (SDP) is a 1-stage register. When an interrupt occurs, this register (SDP) is used to temporarily store the contents of data pointer, carry flag, skip flag, register A, and register B just before an interrupt until returning to the original routine. Unlike the stack registers (SKs), this register (SDP) is not used when executing the subroutine call instruction and the table reference instruction. Stack pointer (SP) points "7" at reset or returning from RAM back-up mode. It points "0" by executing the first BM instruction, and the contents of program counter is stored in SK0. When the BM instruction is executed after eight stack registers are used ((SP) = 7), (SP) = 0 and the contents of SK0 is destroyed.

It determines a sequence in which instructions stored in ROM are read. It is a binary counter that increments the number of instruction bytes each time an instruction is executed. However, the value changes to a specified address when branch instructions, subroutine call instructions, return instructions, or the table reference instruction (TABP p) is executed. Program counter consists of PCH (most significant bit to bit 7) which specifies to a ROM page and PCL (bits 6 to 0) which specifies an address within a page. After it reaches the last address (address 127) of a page, it specifies address 0 of the next page (Figure 7). Make sure that the PCH does not specify after the last page of the built-in ROM.

Register Z specifies a RAM file group, register X specifies a file, and register Y specifies a RAM digit (Figure 8). Register Y is also used to specify the port D bit position. When using port D, set the port D bit position to register Y certainly and execute the SD, RD, or SZD instruction (Figure 9). * Note Register Z of data pointer is undefined after system is released from reset.

An interrupt occurs when the following 3 conditions are satisfied. * An interrupt activated condition is satisfied (request flag = "1") * Interrupt enable bit is enabled ("1") * Interrupt enable flag is enabled (INTE = "1") Table 3 shows interrupt sources. (Refer to each interrupt request flag for details of activated conditions.) Table 3 Interrupt sources Priority Interrupt name level 1 External 0 interrupt 2 3 4 5 Timer 1 interrupt Timer 2 interrupt A/D interrupt Serial interface interrupt Activated condition Level change of INT pin Timer 1 underflow Timer 2 underflow Completion of A/D conversion Completion of serial interface transmit/ recieve (1) Interrupt enable flag (INTE) The interrupt enable flag (INTE) controls whether the every interrupt enable/disable. Interrupts are enabled when INTE flag is set to "1" with the EI instruction and disabled when INTE flag is cleared to "0" with the DI instruction. When any interrupt occurs, the INTE flag is automatically cleared to "0," so that other interrupts are disabled until the EI instruction is executed.

Table 4 shows the interrupt request flag, interrupt enable bit and skip instruction. Table 5 shows the interrupt enable bit function. (3) Interrupt request flag When the activated condition for each interrupt is satisfied, the corresponding interrupt request flag is set to "1." Each interrupt request flag is cleared to "0" when either; * an interrupt occurs, or * the next instruction is skipped with a skip instruction. Each interrupt request flag is set when the activated condition is satisfied even if the interrupt is disabled by the INTE flag or its interrupt enable bit. Once set, the interrupt request flag retains set until a clear condition is satisfied. Accordingly, an interrupt occurs when the interrupt disable state is released while the interrupt request flag is set. If more than one interrupt request flag is set when the interrupt disable state is released, the interrupt priority level is as follows shown in Table 3. Table 5 Interrupt enable bit function Interrupt enable bit 1 0 Occurrence of interrupt Enabled Disabled Skip instruction Invalid Valid Rev.1.02 2006.12.22 REJ03B0147-0102 page 19 of 140 4509 Group (4) Internal state during an interrupt The internal state of the microcomputer during an interrupt is as follows (Figure 14). * Program counter (PC) An interrupt address is set in program counter. The address to be executed when returning to the main routine is automatically stored in the stack register (SK). * Interrupt enable flag (INTE) INTE flag is cleared to "0" so that interrupts are disabled. * Interrupt request flag Only the request flag for the current interrupt source is cleared to "0." * Data pointer, carry flag, skip flag, registers A and B The contents of these registers and flags are stored automatically in the interrupt stack register (SDP). * Program counter (PC) ...............................................................

Write the branch instruction to an interrupt service routine at an interrupt address. Use the RTI instruction to return from an interrupt service routine. Interrupt enabled by executing the EI instruction is performed after executing 1 instruction (just after the next instruction is executed). Accordingly, when the EI instruction is executed just before the RTI instruction, interrupts are enabled after returning the main routine.

(7) Interrupt sequence Interrupts only occur when the respective INTE flag, interrupt enable bits (V10, V12, V13, V22, V23), and interrupt request flag are "1." The interrupt actually occurs 2 to 3 machine cycles after the cycle in which all three conditions are satisfied. The interrupt occurs after 3 machine cycles only when the three interrupt conditions are satisfied on execution of other than one-cycle instructions (Refer to Figure 16).

An external interrupt request occurs when a valid waveform is input to an interrupt input pin (edge detection). The external interrupt can be controlled with the interrupt control register I1. Table 7 External interrupt activated conditions Name External 0 interrupt Input pin P13/INT Activated condition When the next waveform is input to P13/INT pin * Falling waveform ("H""L") * Rising waveform ("L""H") * Both rising and falling waveforms I11 I12 Valid waveform selection bit (Note 1) P13/INT I12 Falling 0 1 One-sided edge detection circuit I11 0 EXF0 1 Both edges detection circuit External 0 interrupt Rising I13 SNZI0 instruction Skip L10 (Note 2) Level detection circuit Edge detection circuit (Note 3) Timer 1 count start synchronization circuit input L11 0 Key-on wakeup input 1 This symbol represents a parasitic diode on the port. Note 1: * 2: When I12 is 0, "L" level is detected. When I12 is 1, "H" level is detected. 3: When I12 is 0, falling edge is detected. When I12 is 1, rising edge is detected. Fig. 17 External interrupt circuit structure (1) External 0 interrupt request flag (EXF0) External 0 interrupt request flag (EXF0) is set to "1" when a valid waveform is input to P13/INT pin. The valid waveforms causing the interrupt must be retained at their level for 4 clock cycles or more of the system clock (Refer to Figure 16). The state of EXF0 flag can be examined with the skip instruction (SNZ0). Use the interrupt control register V1 to select the interrupt or the skip instruction. The EXF0 flag is cleared to "0" when an interrupt occurs or when the next instruction is skipped with the skip instruction. * External 0 interrupt activated condition External 0 interrupt activated condition is satisfied when a valid waveform is input to P13/INT pin. The valid waveform can be selected from rising waveform, falling waveform or both rising and falling waveforms. An example of how to use the external 0 interrupt is as follows. Set the bit 3 of register I1 to "1" for the INT pin to be in the input enabled state. Select the valid waveform with the bits 1 and 2 of register I1. Clear the EXF0 flag to "0" with the SNZ0 instruction. Set the NOP instruction for the case when a skip is performed with the SNZ0 instruction. Set both the external 0 interrupt enable bit (V10) and the INTE flag to "1." The external 0 interrupt is now enabled. Now when a valid waveform is input to the P13/INT pin, the EXF0 flag is set to "1" and the external 0 interrupt occurs.

Rev.1.02 2006.12.22 REJ03B0147-0102 page 29 of 140 4509 Group (1) Timer control registers * Timer control register PA Register PA controls the count operation of prescaler. Set the contents of this register through register A with the TPAA instruction. * Timer control register W1 Register W1 controls the count operation and count source of timer 1, and PWM1 function. Set the contents of this register through register A with the TW1A instruction. The TAW1 instruction can be used to transfer the contents of register W1 to register A. * Timer control register W2 Register W2 controls the count operation and count source of timer 2, and PWM2 function. Set the contents of this register through register A with the TW2A instruction. The TAW2 instruction can be used to transfer the contents of register W2 to register A. * Timer control register W5 Register W5 controls the input count edge of CNTR0 pin, timer 1 count start synchronous circuit, timer 1 auto-stop circuit and P12/ CNTR0 pin function. Set the contents of this register through register A with the TW5A instruction. The TAW5 instruction can be used to transfer the contents of register W5 to register A. * Timer control register W6 Register W6 controls the input count edge of CNTR1 pin, the INT pin input count start synchronous circuit and CNTR1 pin output auto-control circuit and the P11/CNTR1 pin function. Set the contents of this register through register A with the TW6A instruction. The TAW6 instruction can be used to transfer the contents of register W6 to register A. (3) Timer 1 (interrupt function) Timer 1 is an 8-bit binary down counter with two timer 1 reload registers (R1L, R1H). Data can be set simultaneously in timer 1 and the reload register R1L with the T1AB instruction. Data can be set in the reload register R1H with the T1HAB instruction. The contents of reload register R1L set with the T1AB instruction can be set to timer 1 again with the T1R1L instruction. Data can be read from timer 1 with the TAB1 instruction. Stop counting and then execute the T1AB or TAB1 instruction to read or set timer 1 data. When executing the T1HAB instruction to set data to reload register R1H while timer 1 is operating, avoid a timing when timer 1 underflows. Timer 1 starts counting after the following process; set data in timer 1 set count source by bits 0 and 1 of register W1, and set the bit 2 of register W1 to "1." When a value set in reload register R1L is n and a value set in reload register R1H is m, timer 1 divides the count source signal by n + 1 or m + 1 (n = 0 to 255, m = 0 to 255). (2) Prescaler Prescaler is an 8-bit binary down counter with the prescaler reload register RPS. Data can be set simultaneously in prescaler and the reload register RPS with the TPSAB instruction. Data can be read from reload register RPS with the TABPS instruction. Stop counting and then execute the TPSAB or TABPS instruction to read or set prescaler data. Prescaler starts counting after the following process; set data in prescaler, and set the bit 0 of register PA to "1." When a value set in reload register RPS is n, prescaler divides the count source signal by n + 1 (n = 0 to 255). Count source for prescaler is the instruction clock (INSTCK). Once count is started, when prescaler underflows (the next count pulse is input after the contents of prescaler becomes "0"), new data is loaded from reload register RPS, and count continues (auto-reload function). The output signal (ORCLK) of prescaler can be used for timer 1 and 2 count sources. Rev.1.02 2006.12.22 REJ03B0147-0102 page 30 of 140 4509 Group (4) Timer 2 (interrupt function) Timer 2 is an 8-bit binary down counter with two timer 2 reload registers (R2L, R2H). Data can be set simultaneously in timer 2 and the reload register R2L with the T2AB instruction. Data can be set in the reload register R2H with the T2HAB instruction. The contents of reload register R2L set with the T2AB instruction can be set to timer 2 again with the T2R2L instruction. Data can be read from timer 2 with the TAB2 instruction. Stop counting and then execute the T2AB or TAB2 instruction to read or set timer 2 data. When executing the T2HAB instruction to set data to reload register R2H while timer 2 is operating, avoid a timing when timer 2 underflows. Timer 2 starts counting after the following process; set data in timer 2 set count source by bits 0 and 1 of register W2, and set the bit 2 of register W2 to "1." When a value set in reload register R2L is n and a value set in reload register R2H is m, timer 2 divides the count source signal by n + 1 or m + 1 (n = 0 to 255, m = 0 to 255). Once count is started, when timer 2 underflows (the next count pulse is input after the contents of timer 2 becomes "0"), the timer 2 interrupt request flag (T2F) is set to "1," new data is loaded from reload register R2L, and count continues (auto-reload function). (5) Count start synchronization circuit (timer 1) Timer 1 has the count start synchronous circuit which synchronizes the input of INT pin, and can start the timer count operation. Timer 1 count start synchronous circuit function can be selected after timer 1 control by INT pin is enabled by setting the bit 0 of register I1 to "1" and its function is selected by setting the bit 1 of register W5 to "1". When timer 1 count start synchronous circuit is used, the count start synchronous circuit is set, the count source is input to timer by inputting valid waveform to INT pin. The valid waveform of INT pin to set the count start synchronous circuit is the same as the external interrupt activated condition. Once set, the count start synchronous circuit is cleared by clearing the bit I10 to "0" or system reset. However, when the count auto-stop circuit is selected (W22 = "1"), the count start synchronous circuit is cleared (auto-stop) at the timer 1 underflow. (6) Count auto-stop circuit (timer 1) Timer 1 has the count auto-stop circuit which is used to stop timer 1 automatically by the timer 1 underflow when the count start synchronous circuit is used. The count auto-stop circuit is valid by setting the bit 2 of register W5 to "1". It is cleared by the timer 1 underflow and the count source to timer 1 is stopped. This function is valid only when the timer 1 count start synchronous circuit is selected. (7) INT pin input period count circuit (timer 2) Timer 2 has the INT pin input period count circuit to count the valid waveform input interval of the INT pin. When bit 1 of register W6 is set to "1", the INT pin input period count circuit of timer 2 becomes valid, and the count source is input. The count source input is stopped by the next input of valid waveform to the INT pin. Then, every a valid waveform is input to the INT pin, start/stop of the count source input is alternately repeated. A valid waveform of the INT pin input is the same as the activated condition of an external interrupt. The INT pin input period count circuit set once is cleared by setting the INT pin input to be disabled state. The INT pin input can be disabled by clearing bit 3 of register I1 to "0". (8) Timer input/output pin (P12/CNTR0 pin, P11/ CNTR1 pin) CNTR0 pin is used to input the timer 2 count source and output the PWM1 signal generated by timer 1. CNTR1 pin is used to input the timer 1 count source and output the PWM2 signal generated by timer 2. The P12/CNTR0 pin function can be selected by bit 3 of register W5. The P11/CNTR1 pin function can be selected by bit 3 of register W6. When the CNTR0 input is selected for timer 2 count source, timer 2 counts the falling or rising waveform of CNTR0 input. The count edge is selected by bit 0 of register W5. When the CNTR1 input is selected for timer 1 count source, timer 1 counts the falling or rising waveform of CNTR1 input. The count edge is selected by bit 0 of register W6. Rev.1.02 2006.12.22 REJ03B0147-0102 page 31 of 140 4509 Group (9) PWM1 output function (P12/CNTR0, timer 1) When bit 3 of register W1 is set to "1", the data is reloaded alternately from reload register R1L and R1H every timer 1 underflow. Timer 1 generates the PWM1 signal of the "L" interval set as reload register R1L, and the "H" interval set as reload register R1H. In this time, the PWM1 signal generated by timer 1 is output from CNTR0 pin by setting "1" to bit 3 of register W5. When the TW1A instruction is executed while the PWM1 signal is "H", the contents of register W1 is changed after the "H" interval of the PWM1 signal is ended. (12) Precautions - Prescaler Stop prescaler counting and then execute the TABPS instruction to read its data. Stop prescaler counting and then execute the TPSAB instruction to write data to prescaler. - Timer count source Stop timer 1 or 2 counting to change its count source. - Reading the count value Stop timer 1 or 2 counting and then execute the TAB1 or TAB2 instruction to read its data. - Writing to the timer Stop timer 1 or 2 counting and then execute the T1AB, T1R1L, T2AB or T2R2L instruction to write data to timer. - Writing to reload register In order to write a data to the reload register R1H while the timer 1 is operating, execute the T1HAB instruction except a timing of the timer 1 underflow. In order to write a data to the reload register R2H while the timer 2 is operating, execute the T2HAB instruction except a timing of the timer 2 underflow. - PWM signal (PWM1, PWM2) If the timer 1 count stop timing and the timer 1 underflow timing overlap during output of the PWM1 signal, a hazard may occur in the PWM1 output waveform. If the timer 2 count stop timing and the timer 2 underflow timing overlap during output of the PWM2 signal, a hazard may occur in the PWM2 output waveform. - Prescaler, timer 1 and timer 2 count start timing and count time when operation starts Count starts from the first rising edge of the count source (2) after prescaler and timer operations start (1). Time to first underflow (3) is shorter (for up to 1 period of the count source) than time among next underflow (4) by the timing to start the timer and count source operations after count starts. When selecting CNTR input as the count source of timer, timer operates synchronizing with the count edge (falling edge or rising edge) of CNTR input selected by software. (10) PWM2 output function (P11/CNTR1, timer 1, timer 2) When bit 3 of register W2 is set to "1", the data is reloaded alternately from reload register R2L and R2H every timer 2 underflow. Timer 2 generates the PWM2 signal of the "L" interval set as reload register R2L, and the "H" interval set as reload register R2H. In this time, the PWM2 signal generated by timer 2 is output from CNTR1 pin by setting "1" to bit 3 of register W6. When bit 2 of register W6 is set to "1", the PWM2 signal output to CNTR1 pin is switched to valid/invalid alternately each timer 1 underflow. However, when timer 1 is stopped (bit 2 of register W1 is cleared to "0"), this function is canceled. When the TW2A instruction is executed while the PWM2 signal is "H", the contents of register W2 is changed after the "H" interval of the PWM2 signal is ended. (11) Timer interrupt request flags (T1F, T2F) Each timer interrupt request flag is set to "1" when each timer underflows. The state of these flags can be examined with the skip instructions (SNZT1, SNZT2). Use the interrupt control register V1, V2 to select an interrupt or a skip instruction. An interrupt request flag is cleared to "0" when an interrupt occurs or when the next instruction is skipped with a skip instruction.

Fig. 27 Timer count start/stop timing Rev.1.02 2006.12.22 REJ03B0147-0102 page 35 of 140 4509 Group WATCHDOG TIMER Watchdog timer provides a method to reset the system when a program run-away occurs. Watchdog timer consists of timer WDT(16-bit binary counter), watchdog timer enable flag (WEF), and watchdog timer flags (WDF1, WDF2). The timer WDT downcounts the instruction clocks as the count source from "FFFF16" after system is released from reset. After the count is started, when the timer WDT underflow occurs (after the count value of timer WDT reaches "FFFF16," the next count pulse is input), the WDF1 flag is set to "1." If the WRST instruction is never executed until the timer WDT underflow occurs (until timer WDT counts 65534), WDF2 flag is set to "1," and the RESET pin outputs "L" level to reset the microcomputer. Execute the WRST instruction at each period of 65534 machine cycle or less by software when using watchdog timer to keep the microcomputer operating normally. When the WEF flag is set to "1" after system is released from reset, the watchdog timer function is valid. When the DWDT instruction and the WRST instruction are executed continuously, the WEF flag is cleared to "0" and the watchdog timer function is invalid. The WEF flag is set to "1" at system reset or RAM back-up mode. The WRST instruction has the skip function. When the WRST instruction is executed while the WDF1 flag is "1", the WDF1 flag is cleared to "0" and the next instruction is skipped. When the WRST instruction is executed while the WDF1 flag is "0", the next instruction is not skipped. The skip function of the WRST instruction can be used even when the watchdog timer function is invalid. FFFF16 Value of 16-bit timer (WDT) 000016 WDF1 flag 65534 count (Note) WDF2 flag RESET pin output Reset released WRST instruction executed (skip executed) System reset After system is released from reset (= after program is started), timer WDT starts count down. When timer WDT underflow occurs, WDF1 flag is set to "1." When the WRST instruction is executed while the WDF1 flag is "1", WDF1 flag is cleared to "0," the next instruction is skipped. When timer WDT underflow occurs while WDF1 flag is "1," WDF2 flag is set to "1" and the watchdog reset signal is output. The output transistor of RESET pin is turned "ON" by the watchdog reset signal and system reset is executed. Note: The number of count is equal to the number of machine cycle because the count source of watchdog timer is the instruction clock. Fig. 28 Watchdog timer function Rev.1.02 2006.12.22 REJ03B0147-0102 page 36 of 140 4509 Group When the watchdog timer is used, clear the WDF1 flag at the period of 65534 machine cycles or less with the WRST instruction. When the watchdog timer is not used, execute the DWDT instruction and the WRST instruction continuously (refer to Figure 29). The watchdog timer is not stopped with only the DWDT instruction. The contents of WDF1 flag and timer WDT are initialized at the RAM back-up mode. When using the watchdog timer and the RAM back-up mode, initialize the WDF1 flag with the WRST instruction just before the microcomputer enters the RAM back-up state (refer to Figure 30) Also, set the NOP instruction after the WRST instruction, for the case when a skip is performed with the WRST instruction.

Table 11 shows the characteristics of this A/D converter. This A/D converter can also be used as an 8-bit comparator to compare analog voltages input from the analog input pin with preset values.

The value of the comparator register is retained even when the mode is switched to the A/D conversion mode (Q13=0) because it is separated from the successive comparison register (AD). Also, the resolution in the comparator mode is 8 bits because the comparator register consists of 8 bits.

(1) A/D control register Q1 Register Q1 is used to select the operation mode and one of analog input pins. Set the contents of this register through register A with the TQ1A instruction. The TAQ1 instruction can be used to transfer the contents of register Q1 to register A. (6) Operation description A/D conversion is started with the A/D conversion start instruction (ADST). The internal operation during A/D conversion is as follows: When the A/D conversion starts, the register AD is cleared to "00016." Next, the topmost bit of the register AD is set to "1," and the comparison voltage Vref is compared with the analog input voltage VIN. When the comparison result is Vref < VIN, the topmost bit of the register AD remains set to "1." When the comparison result is Vref > VIN, it is cleared to "0." The 4509 Group repeats this operation to the lowermost bit of the register AD to convert an analog value to a digital value. A/D conversion stops after 62 machine cycles (31 s when f(XIN) = 6.0 MHz in high-speed mode) from the start, and the conversion result is stored in the register AD. An A/D interrupt activated condition is satisfied and the ADF flag is set to "1" as soon as A/D conversion completes (Figure 32). (2) Operating at A/D conversion mode The A/D conversion mode is set by setting the bit 3 of register Q1 to "0." (3) Successive comparison register AD Register AD stores the A/D conversion result of an analog input in 10-bit digital data format. The contents of the high-order 8 bits of this register can be stored in register B and register A with the TABAD instruction. The contents of the low-order 2 bits of this register can be stored into the high-order 2 bits of register A with the TALA instruction. However, do not execute these instructions during A/D conversion. When the contents of register AD is n, the logic value of the comparison voltage Vref generated from the built-in DA converter can be obtained with the reference voltage VDD by the following formula: Logic value of comparison voltage Vref Vref = VDD 1024 n n: The value of register AD (n = 0 to 1023) (4) A/D conversion completion flag (ADF) A/D conversion completion flag (ADF) is set to "1" when A/D conversion completes. The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction. The ADF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction. (5) A/D conversion start instruction (ADST) A/D conversion starts when the ADST instruction is executed. The conversion result is automatically stored in the register AD.

ADST instruction 62 machine cycles A/D conversion completion flag (ADF) DAC operation signal Fig. 32 A/D conversion timing chart (8) How to use A/D conversion How to use A/D conversion is explained using as example in which the analog input from P20/AIN0 pin is A/D converted, and the high-order 4 bits of the converted data are stored in address M(Z, X, Y) = (0, 0, 0), the middle-order 4 bits in address M(Z, X, Y) = (0, 0, 1), and the low-order 2 bits in address M(Z, X, Y) = (0, 0, 2) of RAM. The A/ D interrupt is not used in this example. Select the AIN0 pin function and A/D conversion mode with the register Q1 (refer to Figure 33). Execute the ADST instruction and start A/D conversion. Examine the state of ADF flag with the SNZAD instruction to determine the end of A/D conversion. Transfer the low-order 2 bits of converted data to the high-order 2 bits of register A (TALA instruction). Transfer the contents of register A to M (Z, X, Y) = (0, 0, 2). Transfer the high-order 8 bits of converted data to registers A and B (TABAD instruction). Transfer the contents of register A to M (Z, X, Y) = (0, 0, 1). Transfer the contents of register B to register A, and then, store into M(Z, X, Y) = (0, 0, 0).

Below, the operation at comparator mode is described. (12) Comparator operation start instruction (ADST instruction) In comparator mode, executing ADST starts the comparator operating. The comparator stops 8 machine cycles after it has started (6 s at f(XIN) = 4.0 MHz in high-speed through mode). When the analog input voltage is lower than the comparison voltage, the ADF flag is set to "1." (10) Comparator register In comparator mode, the built-in DA comparator is connected to the 8-bit comparator register as a register for setting comparison voltages. The contents of register B is stored in the high-order 4 bits of the comparator register and the contents of register A is stored in the low-order 4 bits of the comparator register with the TADAB instruction. When changing from A/D conversion mode to comparator mode, the result of A/D conversion (register AD) is undefined. However, because the comparator register is separated from register AD, the value is retained even when changing from comparator mode to A/D conversion mode. Note that the comparator register can be written and read at only comparator mode. If the value in the comparator register is n, the logic value of comparison voltage Vref generated by the built-in DA converter can be determined from the following formula: Logic value of comparison voltage Vref Vref = VDD 256 n (13) Notes for the use of A/D conversion 1 * TALA instruction When the TALA instruction is executed, the low-order 2 bits of register AD is transferred to the high-order 2 bits of register A, simultaneously, the low-order 2 bits of register A is "0." * Operating mode of A/D converter Do not change the operating mode (both A/D conversion mode and comparator mode) of A/D converter with the bit 3 of register Q1 while the A/D converter is operating. Clear the bit 2 of register V2 to "0" to change the operating mode from the comparator mode to A/D conversion mode. The A/D conversion completion flag (ADF) may be set when the operating mode of the A/D converter is changed from the comparator mode to the A/D conversion mode. Accordingly, set a value to the bit 3 of register Q1, and execute the SNZAD instruction to clear the ADF flag. n: The value of register AD (n = 0 to 255) (11) Comparison result store flag (ADF) In comparator mode, the ADF flag, which shows completion of A/D conversion, stores the results of comparing the analog input voltage with the comparison voltage. When the analog input voltage is lower than the comparison voltage, the ADF flag is set to "1." The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction. The ADF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction.

Serial interface consists of; * Serial interface register SI * Serial interface control register J1 * Serial interface transmit/receive completion flag (SIOF) * Serial interface counter Registers A and B are used to perform data transfer with internal CPU. The pin functions of the serial interface pins can be set with the register J1.

Data can be set to register SI through registers A and B with the TSIAB instruction. The contents of register A is transmitted to the low-order 4 bits of register SI, and the contents of register B is transmitted to the high-order 4 bits of register SI. During transmission, each bit data is transmitted LSB first from the lowermost bit (bit 0) of register SI, and during reception, each bit data is received LSB first to register SI starting from the topmost bit (bit 7). When register SI is used as a work register without using serial interface, do not select the SCK pin. (3) Serial interface start instruction (SST) When the SST instruction is executed, the SIOF flag is cleared to "0" and then serial interface transmission/reception is started. (4) Serial interface control register J1 Register J1 controls the synchronous clock, P02/SCK, P01/SOUT and P00/SIN pin function. Set the contents of this register through register A with the TJ1A instruction. The TAJ1 instruction can be used to transfer the contents of register J1 to register A. (2) Serial interface transmit/receive completion flag (SIOF) Serial interface transmit/receive completion flag (SIOF) is set to "1" when serial data transmission or reception completes. The state of SIOF flag can be examined with the skip instruction (SNZSI). Use the interrupt control register V2 to select the interrupt or the skip instruction. The SIOF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction.

(1) SVDE instruction If the SVDE instruction is not executed (initial state), the voltage drop detection circuit becomes invalid at RAM back-up mode. When the SVDE instruction is executed, the voltage drop deteciton circuit is valid even after system enters into the RAM back-up mode. The SVDE instruction can be executed only once. In order to release the execution of the SVDE instruction, the system reset is required.

When the POF instruction is executed continuously after the EPOF instruction, system enters the RAM back-up state. The POF instruction is equal to the NOP instruction when the EPOF instruction is not executed before the POF instruction. As oscillation stops retaining RAM, the function of reset circuit and states at RAM back-up mode, current dissipation can be reduced without losing the contents of RAM. Table 19 shows the function and states retained at RAM back-up. Figure 46 shows the state transition.

Figure 49 shows the structure of the clock control circuit. The 4509 Group operates by the on-chip oscillator clock (f(RING)) which is the internal oscillator after system is released from reset.

The clock frequency of the on-chip oscillator depends on the supply voltage and the operation temperature range. Be careful that variable frequencies when designing application products. Main clock f(XIN) * Ceramic oscillation valid * RC oscillation invalid CRCK instruction * Ceramic oscillation invalid * RC oscillation valid Reset (2) Main clock generating circuit (f(XIN)) The ceramic resonator or RC oscillation can be used for the main clock of this product. After system is released from reset, the ceramic oscillation is active for main clock. The ceramic oscillation is invalid and the RC oscillation circuit is valid with the CRCK instruction. Execute the CRCK instruction in the initial setting routine of program (executing it in address 0 in page 0 is recommended). The execution of the CRCK instruction can be valid only once. Register MR controls the enable/disable of the oscillation and the selection of the operation source clock. Also, when the MCU operates only by the on-chip oscillator without using main clock f(XIN), connect XIN pin to Vss and leave XOUT pin open, and do not execute the CRCK instruction (Figure 51). Fig. 50 Switch to ceramic oscillation/RC oscillation 4509 * Do not execute the CRCK instruction in program. XOUT XIN Fig. 51 Handling of XIN and XOUT when main clock is not used (3) Ceramic resonator When the ceramic resonator is used as the main clock (f(XIN)), connect the ceramic resonator and the external circuit to pins XIN and XOUT at the shortest distance. A feedback resistor is built in between pins XIN and XOUT (Figure 52). Do not execute the CRCK instruction. Set "0" to bit 0 of register MR after the oscillation stabilizing wait time is generated by software to select the clock generated by the ceramic oscillation circuit for the source oscillation clock. 4509 * Do not execute the CRCK instruction in program. XOUT Note: Externally connect a damping resistor Rd depending on the oscillation frequency. Rd (A feedback resistor is built-in.) Use the resonator manufacturer's recommended value COUT because constants such as capacitance depend on the resonator. XIN CIN (4) RC oscillation When the RC oscillation is used as the main clock (f(XIN)), connect the XIN pin to the external circuit of resistor R and the capacitor C at the shortest distance and leave XOUT pin open. Then, execute the CRCK instruction (Figure 53). The frequency is affected by a capacitor, a resistor and a microcomputer. So, set the constants within the recommended operating condition of the frequency limits. Fig. 52 Ceramic resonator external circuit 4509 R C XIN XOUT * Execute the CRCK instruction in program.

Do not execute the CRCK instruction in program. Be careful that the maximum value of the oscillation frequency when using the external clock differs from the value when using the ceramic resonator (refer to the recommended operating condition). Also, note that the RAM back-up mode (POF instruction) cannot be used when using the external clock. 4509 * Do not execute the CRCK instruction in program.

CNVSS pin is also used as VPP pin. Accordingly, when using this pin, connect this pin to VSS through a resistor about 5 k (connect this resistor to CNVSS/VPP pin as close as possible). Note on Power Source Voltage When the power source voltage value of a microcomputer is less than the value which is indicated as the recommended operating conditions, the microcomputer does not operate normally and may perform unstable operation. In a system where the power source voltage drops slowly when the power source voltage drops or the power supply is turned off, reset a microcomputer when the supply voltage is less than the recommended operating conditions and design a system not to cause errors to the system by this unstable operation. Register initial values 1 The initial value of the following registers are undefined after system is released from reset. After system is released from reset, set initial values. * Register Z (2 bits) * Register D (3 bits) * Register E (8 bits) Register initial values 2 The initial value of the following registers are undefined at RAM back-up. After system is returned from RAM back-up, set initial values. * Register Z (2 bits) * Register X (4 bits) * Register Y (4 bits) * Register D (3 bits) * Register E (8 bits) Program counter Make sure that the PCH does not specify after the last page of the built-in ROM. Stack registers (SKS) and stack pointer (SP) Stack registers (SKs) are eight identical registers, so that subroutines can be nested up to 8 levels. However, one of stack registers is used respectively when using an interrupt service routine and when executing a table reference instruction. Accordingly, be careful not to over the stack when performing these operations together. Multifunction - The input/output of P00 can be used even when SIN is used. Be careful when using inputs of both SIN and P00 since the input threshold value of SIN pin is different from that of port P00. - The input of P01 can be used even when SOUT is used. - The input of P02 can be used even when SCK is used. Be careful when using inputs of both SCK and P02 since the input threshold value of SCK pin is different from that of port P02. - The input of P11 can be used even when CNTR1 (output) is selected. The input/output of P11 can be used even when CNTR1 (input) is selected. Be careful when using inputs of both CNTR1 and P11 since the input threshold value of CNTR1 pin is different from that of port P11. - The input of P12 can be used even when CNTR0 (output) is selected. The input/output of P12 can be used even when CNTR0 (input) is selected. Be careful when using inputs of both CNTR0 and P12 since the input threshold value of CNTR0 pin is different from that of port P12. - The input/output of P13 can be used even when INT is used. Be careful when using inputs of both INT and P13 since the input threshold value of INT pin is different from that of port P13. - The input/output of P20, P21, P30, P31, D2, D3 can be used even when AIN0-AIN5 are used. Power-on reset (only for H version) When the built-in power-on reset circuit is used, set the time for the supply voltage to rise from 0 V to the minimum voltage of recommended operating conditions to 100 s or less. If the rising time exceeds 100 s, connect a capacitor between the RESET pin and Vss at the shortest distance, and input "L" level to RESET pin until the value of supply voltage reaches the minimum operating voltage. POF instruction When the POF instruction is executed continuously after the EPOF instruction, system enters the RAM back-up state. Note that system cannot enter the RAM back-up state when executing only the POF instruction. Be sure to disable interrupts by executing the DI instruction before executing the EPOF instruction and the POF instruction continuously. Rev.1.02 2006.12.22 REJ03B0147-0102 page 63 of 140 4509 Group 10 P13/INT pin Note [1] on bit 3 of register I1 When the input of the INT pin is controlled with the bit 3 of register I1 in software, be careful about the following notes. * Depending on the input state of the P13/INT pin, the external 0 interrupt request flag (EXF0) may be set when the bit 3 of register I1 is changed. In order to avoid the occurrence of an unexpected interrupt, clear the bit 0 of register V1 to "0" (refer to Figure 57) and then, change the bit 3 of register I1. In addition, execute the SNZ0 instruction to clear the EXF0 flag to "0" after executing at least one instruction (refer to Figure 57). Also, set the NOP instruction for the case when a skip is performed with the SNZ0 instruction (refer to Figure 57). Note [3] on bit 2 of register I1 When the interrupt valid waveform of the P13/INT pin is changed with the bit 2 of register I1 in software, be careful about the following notes. * Depending on the input state of the P13/INT pin, the external 0 interrupt request flag (EXF0) may be set when the bit 2 of register I1 is changed. In order to avoid the occurrence of an unexpected interrupt, clear the bit 0 of register V1 to "0" (refer to Figure 59) and then, change the bit 2 of register I1. In addition, execute the SNZ0 instruction to clear the EXF0 flag to "0" after executing at least one instruction (refer to Figure 59).

Stop prescaler counting and then execute the TPSAB instruction to write data to prescaler. Timer count source Stop timer 1 or 2 counting to change its count source. Reading the count value Stop timer 1 or 2 counting and then execute the TAB1 or TAB2 instruction to read its data. Writing to the timer Stop timer 1 or 2 counting and then execute the T1AB, T1R1L, T2AB or T2R2L instruction to write data to timer. Writing to reload register In order to write a data to the reload register R1H while the timer 1 is operating, execute the T1HAB instruction except a timing of the timer 1 underflow. In order to write a data to the reload register R2H while the timer 2 is operating, execute the T2HAB instruction except a timing of the timer 2 underflow. Prescaler, timer 1 and timer 2 count start timing and count time when operation starts Count starts from the first rising edge of the count source (2) after prescaler and timer operations start (1). Time to first underflow (3) is shorter (for up to 1 period of the count source) than time among next underflow (4) by the timing to start the timer and count source operations after count starts. When selecting CNTR input as the count source of timer, timer operates synchronizing with the count edge (falling edge or rising edge) of CNTR input selected by software. Count source 18 12 13 Watchdog timer * The watchdog timer function is valid after system is released from reset. When not using the watchdog timer function, execute the DWDT instruction and the WRST instruction continuously, and clear the WEF flag to "0" to stop the watchdog timer function. * The contents of WDF1 flag and timer WDT are initialized at the RAM back-up mode. * When using the watchdog timer and the RAM back-up mode, initialize the WDF1 flag with the WRST instruction just before the microcomputer enters the RAM back-up state. Also, set the NOP instruction after the WRST instruction, for the case when a skip is performed with the WRST instruction. Clock control When the RC oscillation is used as the main clock f(XIN), execute the CRCK instruction in the initial setting routine of program (executing it in address 0 in page 0 is recommended). The oscillation circuit by the CRCK instruction can be selected only once. When the CRCK instruction is not executed, the ceramic oscillation is selected for the main clock f(XIN). Also, when the MCU operates only by the on-chip oscillator without using main clock f(XIN), connect XIN pin to Vss and leave XOUT pin open, and do not execute the CRCK instruction. In order to switch the operation source clock (f(RING)) or f(XIN)), generate the oscillation stabilizing wait time by software first and set the oscillation of the destination clock to be enabled. Registers RG and MR are initialized when system returns from RAM back-up mode. However, the selected contents (CRCK instruction execution state) of main clock (f(XIN)) oscillation circuit is retained. On-chip oscillator The clock frequency of the on-chip oscillator depends on the supply voltage and the operation temperature range. Be careful that variable frequencies when designing application products. Also, when considering the oscillation stabilize wait time for switching clock, be careful that the variable frequency of the on-chip oscillator clock. External clock When the external clock is used for the main clock (f(XIN)), connect the XIN pin to the clock source and leave XOUT pin open. Do not execute the CRCK instruction in program. Be careful that the maximum value of the oscillation frequency when using the external clock differs from the value when using the ceramic resonator (refer to the recommended operating condition). Also, note that the RAM back-up mode (POF instruction) cannot be used when using the external clock. 14 19 15 16 20 Count source (When falling edge of CNTR input is selected) Timer value 21 32 1 0 3 2 1 0 3 2 Timer underflow signal Timer start Fig. 60 Timer count start timing and count time when operation starts 17 PWM signal (PWM1, PWM2) If the timer 1 count stop timing and the timer 1 underflow timing overlap during output of the PWM1 signal, a hazard may occur in the PWM1 output waveform.

Do not change the operating mode (both A/D conversion mode and comparator mode) of A/D converter with the bit 3 of register Q1 while the A/D converter is operating. Clear the bit 2 of register V2 to "0" to change the operating mode from the comparator mode to A/D conversion mode. The A/D conversion completion flag (ADF) may be set when the operating mode of the A/D converter is changed from the comparator mode to the A/D conversion mode. Accordingly, set a value to the bit 3 of register Q1, and execute the SNZAD instruction to clear the ADF flag. 23 Notes for the use of A/D conversion 2 Each analog input pin is equipped with a capacitor which is used to compare the analog voltage. Accordingly, when the analog voltage is input from the circuit with high-impedance and, charge/discharge noise is generated and the sufficient A/D accuracy may not be obtained. Therefore, reduce the impedance or, connect a capacitor (0.01 F to 1 F) to analog input pins (Figure 60). When the overvoltage applied to the A/D conversion circuit may occur, connect an external circuit in order to keep the voltage within the rated range as shown the Figure 61. In addition, test the application products sufficiently.

The contents of QzROM may be overwritten because of overvoltage. Take care especially at turning on the power. (2) As for the product shipped in blank, Renesas does not perform the writing test to user ROM area after the assembly process though the QzROM writing test is performed enough before the assembly process. Therefore, a writing error of approx.0.1 % may occur. Moreover, please note the contact of cables and foreign bodies on a socket, etc. because a writing environment may cause some writing errors. 24 25 Notes On ROM Code Protect (QzROM product shipped after writing) As for the QzROM product shipped after writing, the ROM code protect is specified according to the ROM option setup data in the mask file which is submitted at ordering. The ROM option setup data in the mask file is "0016" for protect enabled or "FF16" for protect disabled. Note that the mask file which has nothing at the ROM option data or has the data other than "0016" and "FF16" can not be accepted. Rev.1.02 2006.12.22 REJ03B0147-0102 page 66 of 140 4509 Group NOTES ON NOISE Countermeasures against noise are described below. The following countermeasures are effective against noise in theory, however, it is necessary not only to take measures as follows but to evaluate before actual use. 1. Shortest wiring length (1) Wiring for RESET pin Make the length of wiring which is connected to the RESET pin as short as possible. Especially, connect a capacitor across the RESET pin and the VSS pin with the shortest possible wiring. (2) Wiring for clock input/output pins * Make the length of wiring which is connected to clock I/O pins as short as possible. * Make the length of wiring across the grounding lead of a capacitor which is connected to an oscillator and the VSS pin of a microcomputer as short as possible. * Separate the VSS pattern only for oscillation from other VSS patterns.

The GND pattern is required to be as close as possible to the GND supplied to VSS. In order to improve the noise reduction, to connect a 5 k resistor serially to the CNVSS pin - GND line may be valid. As well as the above-mentioned, in this case, connect to a GND pattern at the shortest distance. The GND pattern is required to be as close as possible to the GND supplied to VSS.

Connection of bypass capacitor across VSS line and VDD line Connect an approximately 0.1 F bypass capacitor across the VSS line and the VDD line as follows: * Connect a bypass capacitor across the VSS pin and the VDD pin at equal length. * Connect a bypass capacitor across the VSS pin and the VDD pin with the shortest possible wiring. * Use lines with a larger diameter than other signal lines for VSS line and VDD line. * Connect the power source wiring via a bypass capacitor to the VSS pin and the VDD pin. 3. Wiring to analog input pins * Connect an approximately 100 to 1 k resistor to an analog signal line which is connected to an analog input pin in series. Besides, connect the resistor to the microcomputer as close as possible. * Connect an approximately 1000 pF capacitor across the Vss pin and the analog input pin.

Oscillator concerns Take care to prevent an oscillator that generates clocks for a microcomputer operation from being affected by other signals. (1) Keeping oscillator away from large current signal lines Install a microcomputer (and especially an oscillator) as far as possible from signal lines where a current larger than the tolerance of current value flows. (3) Oscillator protection using Vss pattern As for a two-sided printed circuit board, print a Vss pattern on the underside (soldering side) of the position (on the component side) where an oscillator is mounted. Connect the Vss pattern to the microcomputer Vss pin with the shortest possible wiring. Besides, separate this Vss pattern from other Vss patterns.
