circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or mishap. keep safety first in your circuit designs! notes regarding these materials 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 they 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 pass-through current flows internally, and a malfunction may occur. 3. processing before initialization note: when power is first supplied, the product? 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? operation is not guaranteed if they are accessed. rev.6.00 oct.28.2004 page i of xxiv rej09b0138-0600h preface this lsi is a single-chip microcomputer with a 32-bit h8s/2000 cpu core, and a set of on-chip peripheral functions required for system configuration. this lsi is equipped with rom, ram, a bus controller, a data transfer controller (dtc), a programmable pulse generator (ppg), three types of timers, a serial communication interface (sci), a d/a converter, an a/d converter, and i/o ports as on-chip peripheral functions. this lsi is suitable for use as an embedded microcomputer for high-level control systems. its on-chip

of 1016 rej09b0138-0600h section 1 overview 1.1 overview the h8s/2357 group is a series of microcomputers (mcus: microcomputer units), built around the h8s/2000 cpu, employing renesas proprietary architecture, and equipped with peripheral functions on-chip. the h8s/2000 cpu has an internal 32-bit architecture, is provided with sixteen 16-bit general registers and a concise, optimized instruction set designed for high-speed operation, and can address a 16-mbyte linear address space. the instruction set is upward-compatible with h8/300 and h8/300h cpu instructions at the object-code level, facilitating migration from the h8/300, h8/300l, or h8/300h series. on-chip peripheral functions required for system configuration include dma controller (dmac) and data transfer controller (dtc) bus masters, rom and ram memory, a 16-bit timer-pulse unit (tpu), programmable pulse generator (ppg), 8-bit timer, watchdog timer (wdt), serial communication interface (sci), a/d converter, d/a converter, and i/o ports. single-power-supply flash memory (f-ztat* 1 ), prom (ztat* 2 ), and masked rom versions are available, providing a quick and flexible response to conditions from ramp-up through full-scale volume production, even for applications with frequently changing specifications. the features of the h8s/2357 group are shown in table 1-1. notes: 1. f-ztat is a trademark of

(1) program counter (pc): this 24-bit counter indicates the address of the next instruction the cpu will execute. the length of all cpu instructions is 2 bytes (one word), so the least significant pc bit is ignored. (when an instruction is fetched, the least significant pc bit is regarded as 0.) (2) extended control register (exr): this 8-bit register contains the trace bit (t) and three interrupt mask bits (i2 to i0). bit 7?race bit (t): selects trace mode. when this bit is cleared to 0, instructions are executed in sequence. when this bit is set to 1, a trace exception is generated each time an instruction is executed. bits 6 to 3?eserved: these bits are reserved. they are always read as 1. rev.6.00 oct.28.2004 page 29 of 1016 rej09b0138-0600h bits 2 to 0?nterrupt mask bits (i2 to i0): these bits designate the interrupt mask level (0 to 7). for details, refer to section 5, interrupt controller. operations can be performed on the exr bits by the ldc, stc, andc, orc, and xorc instructions. all interrupts, including nmi, are disabled for three states after one of these instructions is executed, except for stc. (3) condition-code register (ccr): this 8-bit register contains internal cpu status information, including an interrupt mask bit (i) and half-carry (h), negative (n), zero (z), overflow (v), and carry (c) flags. bit 7?nterrupt mask bit (i): masks interrupts other than nmi when set to 1. (nmi is accepted regardless of the i bit setting.) the i bit is set to 1 by hardware at the start of an exception-handling sequence. for details, refer to section 5, interrupt controller. bit 6?ser bit or interrupt mask bit (ui): can be written and read by software using the ldc, stc, andc, orc, and xorc instructions. with the h8s/2357 group, this bit cannot be used as an interrupt mask bit. bit 5?alf-carry flag (h): when the add.b, addx.b, sub.b, subx.b, cmp.b, or neg.b instruction is executed, this flag is set to 1 if there is a carry or borrow at bit 3, and cleared to 0 otherwise. when the add.w, sub.w, cmp.w, or neg.w instruction is executed, the h flag is set to 1 if there is a carry or borrow at bit 11, and cleared to 0 otherwise. when the add.l, sub.l, cmp.l, or neg.l instruction is executed, the h flag is set to 1 if there is a carry or borrow at bit 27, and cleared to 0 otherwise. bit 4?ser bit (u): can be written and read by software using the ldc, stc, andc, orc, and xorc instructions. bit 3?egative flag (n): stores the value of the most significant bit (sign bit) of data. bit 2?ero flag (z): set to 1 to indicate zero data, and cleared to 0 to indicate non-zero data. bit 1?verflow flag (v): set to 1 when an arithmetic overflow occurs, and cleared to 0 at other times. bit 0?arry flag (c): set to 1 when a carry occurs, and cleared to 0 otherwise. used by: ? add instructions, to indicate a carry ? subtract instructions, to indicate a borrow ? shift and rotate instructions, to store the value shifted out of the end bit the carry flag is also used as a bit accumulator by bit manipulation instructions. some instructions leave some or all of the flag bits unchanged. for the action of each instruction on the flag bits, refer to appendix a.1, instruction list. operations can be performed on the ccr bits by the ldc, stc, andc, orc, and xorc instructions. the n, z, v, and c flags are used as branching conditions for conditional branch (bcc) instructions. 2.4.4 initial register values reset exception handling loads the cpu's program counter (pc) from the vector table, clears the trace bit in exr to 0, and sets the interrupt mask bits in ccr and exr to 1. the other ccr bits and the general registers are not initialized. in particular, the stack pointer (er7) is not initialized. the stack pointer should therefore be initialized by an mov.l instruction executed immediately after a reset. rev.6.00 oct.28.2004 page 30 of 1016 rej09b0138-0600h 2.5 data formats the cpu can process 1-bit, 4-bit (bcd), 8-bit (byte), 16-bit (word), and 32-bit (longword) data. bit-manipulation instructions operate on 1-bit data by accessing bit n (n = 0, 1, 2, ?

(3) effective address extension: eight, 16, or 32 bits specifying immediate data, an absolute address, or a displacement. (4) condition field: specifies the branching condition of bcc instructions. 2.7 addressing modes and effective address calculation 2.7.1 addressing mode the cpu supports the eight addressing modes listed in table 2-4. each instruction uses a subset of these addressing modes. arithmetic and logic instructions can use the register direct and immediate modes. data transfer instructions can use all addressing modes except program-counter relative and memory indirect. bit manipulation instructions use register direct, register indirect, or absolute addressing mode to specify an operand, and register direct (bset, bclr, bnot, and btst instructions) or immediate (3-bit) addressing mode to specify a bit number in the operand. rev.6.00 oct.28.2004 page 42 of 1016 rej09b0138-0600h table 2-4 addressing modes no. addressing mode symbol 1 register direct rn 2 register indirect @ern 3 register indirect with displacement @(d:16,ern)/@(d:32,ern) 4 register indirect with post-increment register indirect with pre-decrement @ern+ @?rn 5 absolute address @aa:8/@aa:16/@aa:24/@aa:32 6 immediate #xx:8/#xx:16/#xx:32 7 program-counter relative @(d:8,pc)/@(d:16,pc) 8 memory indirect @@aa:8 (1) register direct?n: the register field of the instruction specifies an 8-, 16-, or 32-bit general register containing the operand. r0h to r7h and r0l to r7l can be specified as 8-bit registers. r0 to r7 and e0 to e7 can be specified as 16-bit registers. er0 to er7 can be specified as 32-bit registers. (2) register indirect?ern: the register field of the instruction code specifies an address register (ern) which contains the address of the operand on memory. if the address is a program instruction address, the lower 24 bits are valid and the upper 8 bits are all assumed to be 0 (h'00). (3) register indirect with displacement?(d:16, ern) or @(d:32, ern): a 16-bit or 32-bit displacement contained in the instruction is added to an address register (ern) specified by the register field of the instruction, and the sum gives the address of a memory operand. a 16-bit displacement is sign-extended when added. (4) register indirect with post-increment or pre-decrement?ern+ or @-ern: ? register indirect with post-increment?ern+ the register field of the instruction code specifies an address register (ern) which contains the address of a memory operand. after the operand is accessed, 1, 2, or 4 is added to the address register contents and the sum is stored in the address register. the value added is 1 for byte access, 2 for word transfer instruction, or 4 for longword transfer instruction. for word or longword transfer instruction, the register value should be even. ? register indirect with pre-decrement?-ern the value 1, 2, or 4 is subtracted from an address register (ern) specified by the register field in the instruction code, and the result becomes the address of a memory operand. the result is also stored in the address register. the value subtracted is 1 for byte access, 2 for word transfer instruction, or 4 for longword transfer instruction. for word or longword transfer instruction, the register value should be even. (5) absolute address?aa:8, @aa:16, @aa:24, or @aa:32: the instruction code contains the absolute address of a memory operand. the absolute address may be 8 bits long (@aa:8), 16 bits long (@aa:16), 24 bits long (@aa:24), or 32 bits long (@aa:32). to access data, the absolute address should be 8 bits (@aa:8), 16 bits (@aa:16), or 32 bits (@aa:32) long. for an 8-bit absolute address, the upper 24 bits are all assumed to be 1 (h'ffff). for a 16-bit absolute address the upper 16 bits are a sign extension. a 32-bit absolute address can access the entire address space. a 24-bit absolute address (@aa:24) indicates the address of a program instruction. the upper 8 bits are all assumed to be 0 (h'00). table 2-5 indicates the accessible absolute address ranges. rev.6.00 oct.28.2004 page 43 of 1016 rej09b0138-0600h table 2-5 absolute address access ranges absolute address advanced mode data address 8 bits (@aa:8) h'ffff00 to h'ffffff 16 bits (@aa:16) h'000000 to h'007fff, h'ff8000 to h'ffffff 32 bits (@aa:32) h'000000 to h'ffffff program instruction address 24 bits (@aa:24) (6) immediate?xx:8, #xx:16, or #xx:32: the instruction contains 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) immediate data as an operand. the adds, subs, inc, and dec instructions contain immediate data implicitly. some bit manipulation instructions contain 3-bit immediate data in the instruction code, specifying a bit number. the trapa instruction contains 2-bit immediate data in its instruction code, specifying a vector address. (7) program-counter relative?(d:8, pc) or @(d:16, pc): this mode is used in the bcc and bsr instructions. an 8-bit or 16-bit displacement contained in the instruction is sign-extended and added to the 24-bit pc contents to generate a branch address. only the lower 24 bits of this branch address are valid; the upper 8 bits are all assumed to be 0 (h'00). the pc value to which the displacement is added is the address of the first byte of the next instruction, so the possible branching range is ?26 to +128 bytes (?3 to +64 words) or ?2766 to +32768 bytes (?6383 to +16384 words) from the branch instruction. the resulting value should be an even number. (8) memory indirect?@aa:8: this mode can be used by the jmp and jsr instructions. the instruction code contains an 8-bit absolute address specifying a memory operand. this memory operand contains a branch address. the upper bits of the absolute address are all assumed to be 0, so the address range is 0 to 255 (h'000000 to h'0000ff). note that the first part of the address range is also the exception vector area. for further details, refer to section 4, exception handling. advanced mode specified by @aa:8 reserved branch address figure 2-10 branch address specification in memory indirect mode if an odd address is specified in word or longword memory access, or as a branch address, the least significant bit is regarded as 0, causing data to be accessed or instruction code to be fetched at the address preceding the specified address.

(1) types of exception handling and their priority exception handling is performed for traces, resets, interrupts, and trap instructions. table 2-7 indicates the types of exception handling and their priority. trap instruction exception handling is always accepted, in the program execution state. exception handling and the stack structure depend on the interrupt control mode set in syscr. rev.6.00 oct.28.2004 page 49 of 1016 rej09b0138-0600h table 2-7 exception handling types and priority priority type of exception detection timing start of exception handling high reset synchronized with clock exception handling starts immediately after a low-to-high transition at the res pin, or when the watchdog timer overflows. trace end of instruction execution or end of exception-handling sequence * 1 when the trace (t) bit is set to 1, the trace starts at the end of the current instruction or current exception-handling sequence interrupt end of instruction execution or end of exception-handling sequence * 2 when an interrupt is requested, exception handling starts at the end of the current instruction or current exception-handling sequence low trap instruction when trapa instruction is executed exception handling starts when a trap (trapa) instruction is executed * 3 notes: 1. traces are enabled only in interrupt control mode 2. trace exception-handling is not executed at the end of the rte instruction. 2. interrupts are not detected at the end of the andc, orc, xorc, and ldc instructions, or immediately after reset exception handling. 3. trap instruction exception handling is always accepted, in the program execution state. (2) reset exception handling after the res pin has gone low and the reset state has been entered, when res goes high again, reset exception handling starts. the cpu enters the power-on reset state when the nmi pin is high, or the manual reset* state when the nmi pin is low. when reset exception handling starts the cpu fetches a start address (vector) from the exception vector table and starts program execution from that address. all interrupts, including nmi, are disabled during reset exception handling and after it ends. note : * manual reset is only supported in the h8s/2357 ztat. (3) traces traces are enabled only in interrupt control mode 2. trace mode is entered when the t bit of exr is set to 1. when trace mode is established, trace exception handling starts at the end of each instruction. at the end of a trace exception-handling sequence, the t bit of exr is cleared to 0 and trace mode is cleared. interrupt masks are not affected. the t bit saved on the stack retains its value of 1, and when the rte instruction is executed to return from the trace exception-handling routine, trace mode is entered again. trace exception-handling is not executed at the end of the rte instruction. trace mode is not entered in interrupt control mode 0, regardless of the state of the t bit. (4) interrupt exception handling and trap instruction exception handling when interrupt or trap-instruction exception handling begins, the cpu references the stack pointer (er7) and pushes the program counter and other control registers onto the stack. next, the cpu alters the settings of the interrupt mask bits in the control registers. then the cpu fetches a start address (vector) from the exception vector table and program execution starts from that start address. rev.6.00 oct.28.2004 page 50 of 1016 rej09b0138-0600h figure 2-13 shows the stack after exception handling ends.

(1) sleep mode: a transition to sleep mode is made if the sleep instruction is executed while the software standby bit (ssby) in the standby control register (sbycr) is cleared to 0. in sleep mode, cpu operations stop immediately after execution of the sleep instruction. the contents of cpu registers are retained. (2) software standby mode: a transition to software standby mode is made if the sleep instruction is executed while the ssby bit in sbycr is set to 1. in software standby mode, the cpu and clock halt and all mcu operations stop. as long as a specified voltage is supplied, the contents of cpu registers and on-chip ram are retained. the i/o ports also remain in their existing states. rev.6.00 oct.28.2004 page 51 of 1016 rej09b0138-0600h (3) hardware standby mode: a transition to hardware standby mode is made when the stby pin goes low. in hardware standby mode, the cpu and clock halt and all mcu operations stop. the on-chip supporting modules are reset, but as long as a specified voltage is supplied, on-chip ram contents are retained. 2.9 basic timing 2.9.1 overview the cpu is driven by a system clock, denoted by the symbol ? the period from one rising edge of ?to the next is referred to as a "state." the memory cycle or bus cycle consists of one, two, or three states. different methods are used to access on-chip memory, on-chip supporting modules, and the external address space. 2.9.2 on-chip memory (rom, ram) on-chip memory is accessed in one state. the data bus is 16 bits wide, permitting both byte and word transfer instruction. figure 2-14 shows the on-chip memory access cycle. figure 2-15 shows the pin states. internal address bus internal read signal internal data

external address space is accessed with an 8-bit or 16-bit data bus width in a two-state or three-state bus cycle. in three-state access, wait states can be inserted. for further details, refer to section 6, bus controller. 2.10 usage note 2.10.1 tas instruction only register er0, er1, er4, or er5 should be used when using the tas instruction. the tas instruction is not generated by the renesas h8s and h8/300 series c/c++ compilers. if the tas instruction is used as a user-defined intrinsic function, ensure that only register er0, er1, er4, or er5 is used. rev.6.00 oct.28.2004 page 54 of

eight operating modes (modes 4 to 7, 10, 11, 14 and 15). these modes are determined by the mode pin (md 2 to md 0 ) and flash write enable pin (fwe) settings. the cpu operating mode and initial bus width can be selected as shown in table 3-1. table 3-1 lists the mcu operating modes. table 3-1 mcu operating mode selection (h8s/2357 f-ztat only) mcu cpu external data bus operating mode fwe md 2 md

bits 15 1 the cpu's architecture allows for 4 gbytes of address space, but the h8s/2357 group actually accesses a maximum of 16 mbytes. modes 4 to 6 are externally expanded modes that allow access to external memory and peripheral devices. the external expansion modes allow switching between 8-bit and 16-bit bus modes. after program execution starts, an 8- bit or 16-bit address space can be set for each area, depending on the bus controller setting. if 16-bit access is selected fo r any one area, 16-bit bus mode is set; if 8-bit access is selected for all areas, 8-bit bus mode is set. note that the functions of each pin depend on the operating mode. modes 10, 11, 14, and 15 are boot modes and user program modes in which the flash memory can be programmed and erased. for details, see section 19, rom. rev.6.00 oct.28.2004 page 56 of 1016 rej09b0138-0600h the h8s/2357 f-ztat can only be used in modes 4 to 7, 10, 11, 14, and 15. this means that the flash write enable pin and mode pins must be set to select one of these modes. do not change the inputs at the mode pins during operation. 3.1.2 operating mode selection (ztat, masked rom, romless version, and h8s/2398 f-ztat) the h8s/2357 group has four operating modes (modes 4 to 7). these modes enable selection of the cpu operating mode, enabling/disabling of on-chip rom, and the initial bus width setting, by setting the mode pins (md 2 to md 0 ). table 3-2 lists the mcu operating modes. table 3-2 mcu operating mode selection (ztat, masked rom, romless , and h8s/2398 f-ztat) mcu cpu external data bus operating mode md

h8s/2398 f- ztat version, refer to table 19-35 in section 19.17, on-board programming modes. in addition, for details on user program mode, refer also to tables 19-35 in section 19.17, on-board programming modes. 2. in romless version, only modes 4 and 5 are available. the cpu's architecture allows for 4 gbytes of address space, but the h8s/2357 group actually accesses a maximum of 16 mbytes. modes 4 to 6 are externally expanded modes that allow access to external memory and peripheral devices. the external expansion modes allow switching between 8-bit and 16-bit bus modes. after program execution starts, an 8- bit or 16-bit address space can be set for each area, depending on the bus controller setting. if 16-bit access is selected fo r any one area, 16-bit bus mode is set; if 8-bit access is selected for all areas, 8-bit bus mode is set. note that the functions of each pin depend on the operating mode. the h8s/2357 group cannot be used in modes 4 to 7. this means that the mode pins must be set to select 4 to 7 modes. do not change the inputs at the mode pins during operation. rev.6.00 oct.28.2004 page 57 of 1016 rej09b0138-0600h 3.1.3 register configuration the h8s/2357 group has a mode control register (mdcr) that indicates the inputs at the mode pins (md 2 to md 0 ), and a system control register (syscr) and a system control register 2 (syscr2)* 2 that control the operation of the h8s/2357 group. table 3-3 summarizes these registers. table 3-3 mcu registers name abbreviation r/w initial value address * 1 mode control register mdcr r undetermined

types and priority as table 4-1 indicates, exception handling may be caused by a reset, trap instruction, or interrupt. exception handling is prioritized as shown in table 4-1. if two or more exceptions occur simultaneously, they are accepted and processed in order of priority. trap instruction exceptions are accepted at all times, in the program execution state. exception handling sources, the stack structure, and the operation of the cpu vary depending on the interrupt control mode set by the intm0 and intm1 bits of syscr. table 4-1 exception types and priority priority exception type start of exception handling high reset starts immediately after a low-to-high transition at the res pin, or when the watchdog timer overflows. the cpu enters the power-on reset state when the nmi pin is high, or the manual reset * 4 state when the nmi pin is low. trace * 1 starts when execution of the current instruction or exception handling ends, if the trace (t) bit is set to 1 interrupt starts when execution of the current instruction or exception handling ends, if an interrupt request has been issued * 2 low trap instruction (trapa) * 3 started by execution of a trap instruction (trapa) notes: 1. traces are enabled only in interrupt control mode 2. trace exception handling is not executed after execution of an rte instruction. 2. interrupt detection is not performed on completion of andc, orc, xorc, or ldc instruction execution, or on completion of reset exception handling. 3. trap instruction exception handling requests are accepted at all times in program execution state. 4. manual reset is only supported in the h8s/2357 ztat. rev.6.00 oct.28.2004 page 72 of 1016 rej09b0138-0600h 4.1.2 exception handling operation exceptions originate from various sources. trap instructions and interrupts are handled as follows: 1. the program counter (pc), condition code register (ccr), and extended register (exr) are pushed onto the stack. 2. the interrupt mask bits are updated. the t bit is cleared to 0. 3. a vector address corresponding to the exception source is generated, and program execution starts from that address. for a reset exception, steps 2 and 3 above are carried out. 4.1.3 exception vector table the exception sources are classified as shown in figure 4-1. different vector addresses are assigned to different exception sources. table 4-2 lists the exception sources and their vector addresses. exception sources note: * manual reset is only supported in the h8s/2357 ztat. reset trace interrupts trap instruction

rom available for use after a power-on reset is the 64-kbyte area comprising addresses h'000000 to h'00ffff. care is required when setting vector addresses. in this case, clearing the eae bit in bcrl enables the 128-kbyte (256-kbyte)* area comprising address h'000000 to h'01ffff (h'03ffff)* to be used. note: * since these values are different according to the on-chip rom capacitance, see section

rej09b0138-0600h 4.2 reset 4.2.1 overview a reset has the highest exception priority. when the res pin goes low, all processing halts and the h8s/2357 group enters the reset state. a reset initializes the internal state of the cpu and the registers of on-chip supporting modules. immediately after a reset, interrupt control mode 0 is set. reset exception handling begins when the res pin changes from low to high. in the f-ztat, masked rom, and romless versions, a reset is always a power-on reset, regardless of the nmi pin level at the time. also, a reset caused by the watchdog timer is always a power-on reset, regardless of the setting of the rsts bit in the rstcr register. in the ztat version, a reset may be either a power-on reset or a manual reset*, according to the nmi pin level at the time. a reset caused by the watchdog timer, also, may be either a power-on reset or a manual reset*. for details see section 13, watchdog timer. note: * manual reset is only supported in the h8s/2357 ztat. 4.2.2 reset types a reset can be of either of two types: a power-on reset or a manual reset*. reset types are shown in table 4-3. a power-on reset should be used when powering on. the internal state of the cpu is initialized by either type of reset. a power-on reset also initializes all the registers in th e on-chip supporting modules, while a manual reset* initializes all the registers in the on-chip supporting modules except for the bus controller and i/o ports, which retain their previous states. with a manual reset*, since the on-chip supporting modules are initialized, ports used as on-chip supporting module i/o pins are switched to i/o ports controlled by ddr and dr. table 4-3 reset types reset transition conditions internal state type nmi res cpu on-chip supporting modules power-on reset high low initialized initialized manual reset * low low initialized initialized, except for bus controller and i/o ports a reset caused by the watchdog timer can also be of either of two types: a power-on reset or a manual reset*. note: * manual reset is only supported in the h8s/2357 ztat. rev.6.00 oct.28.2004 page 75 of 1016 rej09b0138-0600h 4.2.3 reset sequence the h8s/2357 group enters the reset state when the res pin goes low. to ensure that the h8s/2357 group is reset, hold the res pin low for at least 20 ms at power-up. to reset the h8s/2357 group during operation, hold the res pin low for at least 20 states. when the res pin goes high after being held low for the necessary time, the h8s/2357 group starts reset exception handling as follows: 1. the internal state of the cpu and the registers of the on-chip supporting modules are initialized, the t bit is cleared to 0 in exr, and the i bit is set to 1 in exr and ccr. 2. the reset exception handling vector address is read and transferred to the pc, and program execution starts from the address indicated by the pc. figure 4-2 show examples of the reset sequence. address bus vector fetch internal

and ccr will not be saved correctly, leading to a program crash. to prevent this, all interrupt requests, including nmi, are disabled immediately after a reset. since the first instruction of a program is always executed immediately after the reset state ends, make sure that this instruction initializes the stack pointer (example: mov.l #xx:32, sp). 4.2.5 state of on-chip supporting modules after reset release after reset release, mstpcr is initialized to h'3fff and all modules except the dmac and dtc enter module stop mode. consequently, on-chip supporting module registers cannot be read or written to. register reading and writing is enabled when module stop mode is exited. 4.3 traces traces are enabled in interrupt control mode 2. trace mode is not activated in interrupt control mode 0, irrespective of the state of the t bit. for details of interrupt control modes, see section 5, interrupt controller. if the t bit in exr is set to 1, trace mode is activated. in trace mode, a trace exception occurs on completion of each instruction. trace mode is canceled by clearing the t bit in exr to 0. it is not affected by interrupt masking. table 4-4 shows the state of ccr and exr after execution of trace exception handling. interrupts are accepted even within the trace exception handling routine. the t bit saved on the stack retains its value of 1, and when control is returned from the trace exception handling routine by the rte instruction, trace mode resumes. trace exception handling is not carried out after execution of the rte instruction. table 4-4 status of ccr and exr after trace exception handling ccr exr interrupt control mode i ui i2 to i0 t 0 trace exception handling cannot be used. 21??0 legend: 1: set to 1 0: cleared to 0 ?: retains value prior to

the on-chip supporting modules. figure 4-3 classifies the interrupt sources and the number of interrupts of each type. the on-chip supporting modules that can request interrupts include the watchdog timer (wdt), refresh timer, 16-bit timer-pulse unit (tpu), 8-bit timer, serial communication interface (sci), data transfer controller (dtc), dma controller (dmac), and a/d converter. each interrupt source has a separate vector address. nmi is the highest-priority interrupt. interrupts are controlled by the interrupt controller. the interrupt controller has two interrupt control modes and can assign interrupts other than nmi to eight priority/mask levels to enable multiplexed interrupt control. for details of interrupts, see section 5, interrupt controller. interrupts external interrupts

interrupt request at each compare match. notes: figure 4-3 interrupt sources and number of interrupts rev.6.00 oct.28.2004 page 78 of 1016 rej09b0138-0600h 4.5 trap instruction trap instruction exception handling starts when a trapa instruction is executed. trap instruction exception handling can be executed at all times in the program execution state. the trapa instruction fetches a start address from a vector table entry corresponding to a vector number from 0 to 3, as specified in the instruction code. table 4-5 shows the status of ccr and exr after execution of trap instruction

should always be accessed by word transfer instruction or longword transfer instruction, and the value of the stack pointer (sp, er7) should always be kept even. use the following instructions to save registers: push.w rn (or mov.w rn, @-sp) push.l ern (or mov.l ern, @-sp) use the following instructions to restore registers: pop.w rn (or mov.w @sp+, rn) pop.l ern (or mov.l @sp+, ern) setting sp to an odd value may lead to a malfunction. figure 4-5 shows an example of what happens when the sp value is odd. sp legend: note: this diagram illustrates an example in which the interrupt control mode

controller has the following features: two interrupt control modes ? any of two interrupt control modes can be set by means of the intm1 and intm0 bits in the system control register (syscr). priorities settable with ipr ? an interrupt priority register (ipr) is provided for setting interrupt priorities. eight priority levels can be set for each module for all interrupts except nmi. ? nmi is assigned the highest priority level of 8, and can be accepted at all times. independent vector addresses ? all interrupt sources are assigned independent vector addresses, making it unnecessary for the source to be identified in the interrupt handling routine. nine external interrupts ? nmi is the highest-priority interrupt, and is accepted at all times. rising edge or falling edge can be selected for nmi. ? falling edge, rising edge, or both edge detection, or level sensing, can be selected for irq7 to irq0. dtc and dmac control ? dtc and dmac activation is performed by means of interrupts. rev.6.00 oct.28.2004 page 82 of 1016 rej09b0138-0600h 5.1.2 block diagram a block diagram of the interrupt controller is shown in figure 5-1. syscr nmi input irq input internal interrupt

external interrupts there are nine external interrupts: nmi and irq7 to irq0. of these, nmi and irq2 to irq0 can be used to restore the h8s/2357 group from software standby mode. nmi interrupt: nmi is the highest-priority interrupt, and is always accepted by the cpu regardless of the status of the cpu interrupt mask bits. the nmieg bit in syscr can be used to select whether an interrupt is requested at a rising edge or a falling edge on the nmi pin. the vector number for nmi interrupt exception handling is 7. irq7 to irq0 interrupts: interrupts irq7 to irq0 are requested by an input signal at pins irq7 to irq0 . interrupts irq7 to irq0 have the following features: using iscr, it is possible to select whether an interrupt is generated by a low level, falling edge, rising edge, or both edges, at pins irq7 to irq0 . enabling or disabling of interrupt requests irq7 to irq0 can be selected with ier. the interrupt priority level can be set with ipr. the status of interrupt requests irq7 to irq0 is indicated in isr. isr flags can be cleared to 0 by software. a block diagram of interrupts irq7 to irq0 is shown in figure 5-2. rev.6.00 oct.28.2004 page 88 of 1016 rej09b0138-0600h

does not depend on whether the relevant pin has been set for input or output. however, when a pin is used as an external interrupt input pin, do not clear the corresponding ddr to 0 and use the pin as an i/o pin for another function. 5.3.2 internal interrupts there are 52 sources for internal interrupts from on-chip supporting modules. for each on-chip supporting module there are flags that indicate the interrupt request status, and enable bits that select enabling or disabling of these interrupts. if both of these are set to 1 for a particular interrupt source, an interrupt request is issued to the interrupt controller. the interrupt priority level can be set by means of ipr. the dmac and dtc can be activated by a tpu, sci, or other interrupt request. when the dmac or dtc is activated by an interrupt, the interrupt control mode and interrupt mask bits are not affected. 5.3.3 interrupt exception handling vector table table 5-4 shows interrupt exception handling sources, vector addresses, and interrupt priorities. for default priorities, the lower the vector number, the higher the priority. priorities among modules can be set by means of the ipr. the situation when two or more modules are set to the same priority, and priorities within a module, are fixed as shown in table5-4. rev.6.00 oct.28.2004 page 89 of 1016 rej09b0138-0600h table 5-4 interrupt sources,

interrupt operations in the h8s/2357 group differ depending on the interrupt control mode. nmi interrupts are accepted at all times except in the reset state and the hardware standby state. in the case of irq interrupts and on-chip supporting module interrupts, an enable bit is provided for each interrupt. clearing an enable bit to 0 disables the corresponding interrupt request. interrupt sources for which the enable bits are set to 1 are controlled by the interrupt controller. table 5-5 shows the interrupt control modes. the interrupt controller performs interrupt control according to the interrupt control mode set by the intm1 and intm0 bits in syscr, the priorities set in ipr, and the masking state indicated by the i and ui bits in the cpu?s ccr, and bits i2 to i0 in exr. table

when an interrupt is selected by 8-level control, its priority is determined and a vector number is generated. if the same value is set for ipr, acceptance of multiple interrupts is enabled, and so only the interrupt source with the highest priority according to the preset default priorities is selected and has a vector number generated. interrupt sources with a lower priority than the accepted

[1] if an interrupt source occurs when the corresponding interrupt enable bit is set to 1, an interrupt request is sent to the interrupt controller. [2] the i bit is then referenced. if the i bit is cleared to 0, the interrupt request is accepted. if the i bit is set to 1, onl y an nmi interrupt is accepted, and other interrupt requests are held pending. [3] interrupt requests are sent to the interrupt controller, the highest-ranked interrupt according to the priority system is accepted, and other interrupt requests are held pending. [4] when an interrupt request is accepted, interrupt exception handling starts after execution of the current instruction has been completed. [5] the pc and ccr are saved to the stack area by interrupt exception handling. the pc saved on the stack shows the address of the first instruction to be executed after returning from the interrupt handling routine. [6] next, the i bit in ccr is set to 1. this masks all interrupts except nmi. [7] a vector address is generated for the accepted interrupt, and execution of the interrupt handling routine starts at the address indicated by the contents of that vector address. rev.6.00 oct.28.2004 page 94 of 1016 rej09b0138-0600h program execution status interrupt generated? nmi irq0 irq1 tei2 i=0 save pc and ccr i ? 1 read vector address branch to interrupt handling routine yes no yes yes yes no no no yes yes no hold pending figure 5-5 flowchart of procedure up to interrupt acceptance in interruptcontrolmode0 rev.6.00 oct.28.2004 page 95 of 1016 rej09b0138-0600h 5.4.3 interrupt control mode 2 eight-level masking is implemented for irq interrupts and on-chip supporting module interrupts by comparing the interrupt mask level set by bits i2 to i0 of exr in the cpu with ipr. figure 5-6 shows a flowchart of the interrupt acceptance operation in this case. [1] if an interrupt source occurs when the corresponding interrupt enable bit is set to 1, an interrupt request is sent to the interrupt controller. [2] when interrupt requests are sent to the interrupt controller, the interrupt with the highest priority according to the interrupt priority levels set in ipr is selected, and lower-priority interrupt requests are held pending. if a number of interrupt requests with the same priority are generated at the same time, the interrupt request with the highest priority according to the priority system shown in table 5-4 is selected. [3] next, the priority of the selected interrupt request is compared with the interrupt mask level set in exr. an interrupt request with a priority no higher than the mask level set at that time is held pending, and only an interrupt request with a priority higher than the interrupt mask level is accepted. [4] when an interrupt request is accepted, interrupt exception handling starts after execution of the current instruction has been completed. [5] the pc, ccr, and exr are saved to the stack area by interrupt exception handling. the pc saved on the stack shows the address of the first instruction to be executed after returning from the interrupt handling routine. [6] the t bit in exr is cleared to 0. the interrupt mask level is rewritten with the priority level of the accepted interrupt. if the accepted interrupt is nmi, the interrupt mask level is set to h'7.

tgiea tgfa tgi0a interrupt signal tier0 write cycle by cpu tgi0a exception handling tier0 address figure 5-8 contention between interrupt generation and disabling the above contention will not occur if an enable bit or interrupt source flag is cleared to 0 while the interrupt is masked. 5.5.2 instructions that disable interrupts instructions that disable interrupts are ldc, andc, orc, and xorc. after any of these instructions is executed, all interrupts including nmi are disabled and the next instruction is always executed. when the i bit is set by one of these instructions, the new value becomes valid two states after execution of the instruction ends. rev.6.00 oct.28.2004 page 100 of 1016 rej09b0138-0600h 5.5.3 times when interrupts are disabled there are times when interrupt acceptance is disabled by the interrupt controller. the interrupt controller disables interrupt acceptance for a 3-state period after the cpu has updated the mask level with an ldc, andc, orc, or xorc instruction. 5.5.4 interrupts during execution of eepmov instruction interrupt operation differs between the eepmov.b instruction and the eepmov.w instruction. with the eepmov.b instruction, an interrupt request (including nmi) issued during the transfer is not accepted until the move is completed. with the eepmov.w instruction, if an interrupt request is issued during the transfer, interrupt exception handling starts at a break in the transfer cycle. the pc value saved on the stack in this case is the address of the next instruction. therefore, if an interrupt is generated during execution of an eepmov.w instruction, the following coding should be used. l1: eepmov.w mov.w r4,r4 bne l1 5.6 dtc and dmac activation by interrupt 5.6.1 overview the dtc and dmac can be activated by an interrupt. in this case, the following options are available: ?

width: a bus width of 8 or 16 bits can be selected with abwcr. an area for which an 8-bit bus is selected functions as an 8-bit access space, and an area for which a 16-bit bus is selected functions as a16-bit access space. if all areas are designated for 8-bit access, 8-bit bus mode is set; if any area is designated for 16-bit access, 16-bit bus mode is set. when the burst rom interface is designated, 16-bit bus mode is always set. number of access states: two or three access states can be selected with astcr. an area for which 2-state access is selected functions as a 2-state access space, and an area for which 3-state access is selected functions as a 3-state access space. with the dram interface and burst rom interface, the number of access states may be determined without regard to astcr. when 2-state access space is designated, wait insertion is disabled. number of program wait states: when 3-state access space is designated by astcr, the number of program wait states

selected according to the operating mode. the bus specifications described here cover basic items only, and the sections on each memory interface (section 6.4, basic bus interface, section 6.5, dram interface, and section 6.7, burst rom interface) should be referred to for further details. area 0: area 0 includes on-chip rom*, and in rom-disabled expansion mode, all of area 0 is external space. in rom- enabled expansion mode, the space excluding on-chip rom* is external space. when area 0 external space is accessed, the cs0 signal can be output. either basic bus interface or burst rom interface can be selected for area 0. note: * applies to the on-chip rom version only. areas 1 and 6: in external expansion mode, all of areas 1 and 6 is external space. when area 1 and 6 external space is accessed, the cs1 and cs6 pin signals respectively can be output. only the basic bus interface can be used for areas 1 and 6. areas 2 to 5: in external expansion mode, all of areas 2 to 5 is external space. when area 2 to 5 external space is accessed, signals cs2 to cs5 can be output. basic bus interface or dram interface can be selected for areas 2 to 5. with the dram interface, signals cs2 to cs5 are used as ras signals. area 7: area 7 includes the on-chip ram and internal i/o registers. in external expansion mode, the space excluding the on-chip ram and internal i/o registers is external space. the on-chip ram is enabled when the rame bit in the system control register (syscr) is set to 1; when the rame bit is cleared to 0, the on-chip ram is disabled and the corresponding space becomes external space . when area 7 external space is accessed, the cs7 signal can be output. only the basic bus interface can be used for the area 7 memory interface. rev.6.00 oct.28.2004 page 124 of 1016 rej09b0138-0600h 6.3.5 chip select signals the h8s/2357 group can output chip select signals ( cs0 to cs7 ) to areas 0 to 7, the signal being driven low when the corresponding external space area is accessed. figure 6-3 shows an example of csn (n = 0 to 7) output timing. enabling or disabling of the csn signal is performed by setting the data direction register (ddr) for the port corresponding to the particular csn pin. in rom-disabled expansion mode, the cs0 pin is placed in the output state after a power-on reset. pins cs1 to cs7 are placed in the input state after a power-on reset, and so the corresponding ddr should be set to 1 when outputting signals cs1 to cs7 . in the rom-enabled expansion mode, pins cs0 to cs7 are all placed in the input state after a power-on reset, and so the corresponding ddr bits should be set to 1 when outputting signals cs0 to cs7 . for details, see section 9, i/o ports. when areas 2 to 5 are designated as dram space, outputs cs2 to cs5 are used as ras signals. bus cycle t 1 t 2 t 3 area n external address address bus csn figure 6-3 csn signal output timing (n = 0 to 7) rev.6.00 oct.28.2004 page 125 of 1016

wcrl (see table 6-3). 6.4.2 data size and data alignment data sizes for the cpu and other internal bus masters are byte, word, and longword. the bus controller has a data alignment function, and when accessing external space, controls whether the upper data bus (d 15 to d 8 ) or lower data bus (d 7 to d 0 ) is used according to the bus specifications for the area being accessed (8-bit access space or 16-bit access space) and the data size. 8-bit access space: figure 6-4 illustrates data alignment control for the 8-bit access space. with the 8-bit access space, the upper data bus (d 15 to d 8 ) is always used for accesses. the amount of data that can be accessed at one time is one byte: a word transfer instruction is performed as two byte accesses, and a longword transfer instruction, as four byte accesses. d 15 d 8 d 7 d 0 upper data bus lower data bus byte size word size 1st bus cycle 2nd bus cycle longword size 1st bus cycle 2nd bus cycle 3rd bus cycle 4th bus cycle figure 6-4

access space. with the 16-bit access space, the upper data bus (d 15 to d 8 ) and lower data bus (d 7 to d 0 ) are used for accesses. the amount of data that can be accessed at one time is one byte or one word, and a longword transfer instruction is executed as two word transfer instructions. in byte access, whether the upper or lower data bus is used is determined by whether the address is even or odd. the upper data bus is used for an even address, and the lower data bus for an odd address. d 15 d 8 d 7 d 0 upper data bus byte size word size 1st bus cycle 2nd bus cycle longword size ?even

). there are two ways of inserting wait states: program wait insertion and pin wait insertion using the wait pin. program wait insertion: from 0 to 3 wait states can be inserted automatically between the t 2 state and t 3 state on an individual area basis in 3-state access space, according to the settings of wcrh and wcrl. pin wait insertion: setting the waite bit in bcrl to 1 enables wait insertion by means of the wait pin. program wait insertion is first carried out according to the settings in wcrh and wcrl. then , if the wait pin is low at the falling edge of ? in the last t 2 or t w state, a t w state is inserted. if the wait pin is held low, t w states are inserted until it goes high. this is useful when inserting four or more t w states, or when changing the number of t w states for different external devices. the waite bit setting applies to all areas. rev.6.00 oct.28.2004 page 137 of 1016 rej09b0138-0600h figure 6-14 shows an example of wait state insertion timing.

with the dram interface, dram can be directly connected to the h8s/2357 group. a dram space of 2, 4, or 8 mbytes can be set by means of bits rmts2 to rmts0 in bcrh. burst operation is also possible, using fast page mode. 6.5.2 setting dram space areas 2 to 5 are designated as dram space by setting bits rmts2 to rmts0 in bcrh. the relation between the settings of bits rmts2 to rmts0 and dram space is shown in table 6-5. possible dram space settings are: one area (area 2), two areas (areas 2 and 3), and four areas (areas 2 to 5). table 6-5 settings of bits rmts2 to rmts0 and corresponding dram

shows the basic access timing for dram space. the basic dram access timing is 4 states. unlike the basic bus interface, the corresponding bits in astcr control only enabling or disabling of wait insertion, and do not affect the number of access states. when the corresponding bit in astcr is cleared to 0, wait states cannot be inserted in the dram access cycle. the 4 states of the basic timing consist of one t p (precharge cycle) state, one t r (row address output cycle), and two t c (column address output cycle) states, t c1 and t c2 . t p csn , ( ras ) read write cas , lcas hwr , ( we ) d

automatically between the t c1 state and t c2 state, according to the settings of wcrh and wcrl. pin wait insertion: when the waite bit in bcrh is set to 1, wait input by means of the wait pin is enabled regardless of the setting of the ast bit in astcr. when dram space is accessed in this state, a program wait is first inserted. if the wait pin is low at the falling edge of ? in the last t c1 or t w state, another t w state is inserted. if the wait pin is held low, t w states are inserted until it goes high. rev.6.00 oct.28.2004 page 142 of 1016 rej09b0138-0600h figure 6-17 shows an

page mode is also provided which can be used when making a number of consecutive accesses to the same row address. this mode enables fast (burst) access of data by simply changing the column address after the row address has been output. burst access can be selected by setting the be bit in mcr to 1. burst access (fast page mode) operation timing: figure 6-20 shows the operation timing for burst access. when there are consecutive access cycles for dram space, the cas signal and column address output cycles (two states) continue as long as the row address is the same for consecutive access cycles. the row address used for the comparison is set with bits mxc1 and mxc0 in mcr. t p csn , ( ras ) read write cas , lcas hwr , ( we ) d 15 to d 0 hwr , ( we ) d 15 to d 0 a 23 to a 0 t r t c1 t

other space, burst operation can be resumed when the same row address in dram space is accessed again. ras down mode to select ras down mode, set the rcdm bit in mcr to 1. if access to dram space is interrupted and another space is accessed, the ras signal is held low during the access to the other space, and burst access is performed if the row address of the next dram space access is the same as the row address of the previous dram space access. figure 6- 21 shows an example of the timing in ras down mode. note, however, that the ras signal will go high if a refresh operation interrupts

refresh control function. either of two refreshing methods can be selected: cas-before-ras (cbr) refreshing, or self-refreshing. cas-before-ras (cbr) refreshing: to select cbr refreshing, set the rfshe bit in dramcr to 1, and clear the rmode bit to 0. with cbr refreshing, rtcnt counts up using the input clock selected by bits cks2 to cks0 in dramcr, and when the count matches the value set in rtcor (compare match), refresh control is performed. at the same time, rtcnt is reset and starts counting again from h'00. refreshing is thus repeated at fixed intervals determined by rtcor and bits cks2 to cks0. set a value in rtcor and bits cks2 to cks0 that will meet the refreshing interval specification for the dram used. when bits cks2 to cks0 are set, rtcnt starts counting up. rtcnt and rtcor settings should therefore be completed before setting bits cks2 to cks0. do not clear the cmf flag when refresh control is being performed (rfshe = 1). rtcnt operation is shown in figure 6-23,

self-refresh mode, as shown in figure 6-27. when software standby mode is exited, the rmode bit is cleared to 0 and self-refresh mode is cleared. when switching to software standby mode, if there is a

burst rom interface 6.7.1 overview with the h8s/2357 group, external space area 0 can be designated as burst rom space, and burst rom interfacing can be performed. the burst rom space interface enables 16-bit configuration rom with burst access capability to be accessed at high speed. area 0 can be designated as burst rom space by means of the brstrm bit in bcrh. consecutive burst accesses of a maximum of 4 words or 8 words can be performed for cpu instruction fetches only. one or two states can be selected for burst access. rev.6.00 oct.28.2004 page 151 of 1016 rej09b0138-0600h 6.7.2 basic timing the number of states in the initial cycle (full access) of the burst rom interface is in accordance with the setting of the ast0 bit in astcr. also, when the ast0 bit is set to 1, wait state insertion is possible. one or two states can be selected for the burst cycle, according to the setting of the brsts1 bit in bcrh. wait states cannot be inserted. when area 0 is designated as burst rom space, it becomes 16-bit access space regardless of the setting of the abw0 bit in abwcr. when the brsts0 bit in bcrh is cleared to 0, burst access of up to 4 words is performed; when the brsts0 bit is set to 1, burst access of up to 8 words is performed. the basic access timing for burst rom space is shown in figures 6-30 (a) and (b). the timing shown in figure 6-30 (a) is for the case where the ast0 and brsts1 bits are both set to 1, and that in figure 6-30 (b) is for the case where both these bits are cleared to 0. t 1 address bus cs0 as data bus t 2 t 3 t 1 t 2 t 1 full

the burst rom interface. see section 6.4.5, wait control. wait states cannot be inserted in a burst cycle. rev.6.00 oct.28.2004 page 153 of 1016 rej09b0138-0600h 6.8 idle cycle 6.8.1 operation when the h8s/2357 group accesses external space, it can insert a 1-state idle cycle (t i ) between bus cycles in the following two cases: (1) when read accesses between different areas occur consecutively, and (2) when a write cycle occurs immediately after a read cycle. by inserting an idle cycle it is possible, for example, to avoid data collisions between rom, with a long output floating time, and high-speed memory, i/o interfaces, and so on. (1) consecutive reads between different areas if consecutive reads between different areas occur while the icis1 bit in bcrh is set to 1, an idle cycle is inserted at the start of the second read cycle. this is enabled in advanced mode. figure 6-31 shows an example of the operation in this case. in this example, bus cycle a is a read cycle from rom with a long output floating time, and bus cycle b is a read cycle from sram, each being located in a different area. in (a), an idle cycle is not inserted, and a collision occurs in cycle b between the read data from rom and that from sram. in (b), an idle cycle is inserted, and a data collision is prevented. t 1 address bus rd bus cycle a data bus t 2 t 3 t 1 t 2 bus cycle b bus cycle a bus cycle b long output floating time data

bcrh is set to 1, an idle cycle is inserted at the start of the write cycle. figure 6-32 shows an example of the operation in this case. in this example, bus cycle a is a read cycle from rom with a long output floating time, and bus cycle b is a cpu write cycle. in (a), an idle cycle is not inserted, and a collision occurs in cycle b between the read data from rom and the cpu write data. in (b), an idle cycle is inserted, and a data collision is prevented. t 1 address bus rd bus cycle a data bus t 2 t 3 t 1 t 2 bus cycle b long output floating time data collision t 1 address bus ? rd bus

system?s load conditions, the rd signal may lag behind the cs signal. an example is shown in figure 6- 33. in this case, with the setting for no idle cycle insertion (a), there may be a period of overlap between the bus cycle a rd signal and the bus cycle b cs signal. setting idle cycle insertion, as in (b), however, will prevent any overlap between the rd and cs signals. in the initial state after reset release, idle cycle insertion (b) is set. t 1 address bus rd bus cycle a t 2 t 3 t 1 t 2 bus cycle b possibility of overlap between cs (area b) and rd t 1 address bus bus cycle a t 2 t 3 t

the second access is a dram access, only a t p cycle is inserted, and a t i cycle is not. the timing in this case is shown in figure 6-34. however, in burst access in ras down mode these settings are enabled, and an idle cycle is inserted. the timing in this case is shown in figures 6-35 (a) and (b). rev.6.00 oct.28.2004 page 156 of 1016 rej09b0138-0600h t 1 address bus rd external read data bus t

external writes and dma single address mode transfers to be executed in parallel with internal accesses. the write data buffer function is made available by setting the wdbe bit in bcrl to 1. figure 6-36 shows an example of the timing when the write data buffer function is used. when this function is used, if an external write or dma single address mode transfer continues for 2 states or longer, and there is an internal access next, only an external write is executed in the first state, but from the next state onward an internal access (on-chip memory or internal i/o register read/write) is executed in parallel with the external write rather than waiting until it ends. t 1 internal address bus note : n = 0 to 7 a 23 to a 0 external write cycle hwr, lwr t 2 t w t w t 3 on-chip memory read

device. in the external bus released state, the internal bus master continues to operate as long as there is no external access. if an internal bus master wants to make an external access in the external bus released state, or if a refresh request is generated, it can issue a bus request off-chip. 6.10.2 operation in external expansion mode, the bus can be released to an external device by setting the brle bit in bcrl to 1. driving the breq pin low issues an external bus request to the h8s/2357 group. when the breq pin is sampled, at the prescribed timing the back pin is driven low, and the address bus, data bus, and bus control signals are placed in the high-impedance state, establishing the external bus-released state. in the external bus released state, an internal bus master can perform accesses using the internal bus. when an internal bus master wants to make an external access, it temporarily defers activation of the bus cycle, and waits for the bus request from the external bus master to be dropped. even if a refresh request is generated in the external bus released state, refresh control is deferred until the external bus master drops the bus request. if the breqoe bit in bcrl is set to 1, when an internal bus master wants to make an external access in the external bus released state, or when a refresh request is generated, the breqo pin is driven low and a request can be made off-chip to drop the bus request. when the breq pin is driven high, the back pin is driven high at the prescribed timing and the external bus released state is terminated. if an external bus release request and external access occur simultaneously, the order of priority is as follows: (high) external bus release > internal bus master external access (low) if a refresh request and external bus release request occur simultaneously, the order of priority is as follows: (high) refresh > external bus release (low) as a refresh and an external access by an internal bus master can be executed simultaneously, there is no relative order of priority for these two operations. rev.6.00 oct.28.2004 page 160 of 1016 rej09b0138-0600h 6.10.3 pin states in external bus released state

bus arbiter that arbitrates bus master operations. there are three bus masters, the cpu, dtc, and dmac, which perform read/write operations when they have possession of the bus. each bus master requests the bus by means of a bus request signal. the bus arbiter determines priorities at the prescribed timing, and permits use of the bus by means of a bus request acknowledge signal. the selected bus master then takes possession of the bus and begins its operation. 6.11.2 operation the bus arbiter detects the bus masters' bus request signals, and if the bus is requested, sends a bus request acknowledge signal to the bus master making the request. if there are bus requests from more than one bus master, the bus request acknowledge signal is sent to the one with the highest priority. when a bus master receives the bus request acknowledge signal, it takes possession of the bus until that signal is canceled. the order of priority of the bus masters is as follows: (high) dmac > dtc > cpu (low) an internal bus access by an internal bus master, external bus release, and refreshing, can be executed in parallel. in the event of simultaneous external bus release request, refresh request, and internal bus master external access request generation, the order of priority is as follows: (high) refresh > external bus release (low) (high) external bus release > internal bus master external access (low) as a refresh and an external access by an internal bus master can be executed simultaneously, there is no relative order of priority for these two operations. rev.6.00 oct.28.2004 page 163 of 1016 rej09b0138-0600h 6.11.3 bus transfer timing even if a bus request is received from a bus master with a higher priority than that of the bus master that has acquired the bus and is currently operating, the bus is not necessarily transferred immediately. there are specific times at which each bus master can relinquish the bus. cpu: the cpu is the lowest-priority bus master, and if a bus request is received from the dtc or dmac, the bus arbiter transfers the bus to the bus master that issued the request. the timing for transfer of the bus is as follows: the bus is transferred at a break between bus cycles. however, if a bus cycle is executed in discrete operations, as in the case of a longword-size access, the bus is not transferred between the operations. see appendix a.5, bus states during instruction execution, for timings at which the bus is not transferred. if the cpu is in sleep mode, it transfers the bus immediately. dtc: the dtc sends the bus arbiter a request for the bus when an activation request is generated. the dtc can release the bus after a vector read, a register information read (3 states), a single data transfer, or a register information write (3 states). it does not release the bus during a register information read (3 states), a single data transfer , or a register information write (3 states). dmac: the dmac sends the bus arbiter a request for the bus when an activation request is generated. in the case of an external request in short address mode or normal mode, and in cycle steal mode, the dmac releases the bus after a single transfer. in block transfer mode, it releases the bus after transfer of one block, and in burst mode, after completion of a transfer. 6.11.4 external bus release usage note external bus release can be performed on completion of an external bus cycle. the rd signal, dram interface ras and cas signals remain low until the end of the external bus cycle. therefore, when external bus release is performed, the rd , ras , and cas signals may change from the low level to the high-impedance state. rev.6.00 oct.28.2004 page 164 of 1016 rej09b0138-0600h 6.12 resets and the bus controller in a power-on reset, the h8s/2357 group, including the bus controller, enters the reset state at that point, and an executing bus cycle is discontinued. in a manual reset*, the bus controller?s registers and internal state are maintained, and an executing external bus cycle is completed. in this case, wait input is ignored. also, since the dmac is initialized by a manual reset*, dack and tend output is disabled and these pins become i/o ports controlled by ddr and dr. note: * manual reset is only supported in the h8s/2357 ztat. rev.6.00 oct.28.2004 page 165 of 1016 rej09b0138-0600h section 7 dma

transfer end interrupt request to the cpu. the conditions for the dte bit being cleared to 0 are as follows: when initialization is performed when the specified number of transfers have been completed when 0 is written to the dte bit to forcibly abort the transfer, or for a similar reason when dte = 1 and dtme = 1, data transfer is enabled and the dmac waits for a request by the activation source selected by the data transfer factor setting. when a request is issued by the activation source, dma transfer is executed. the condition for the dte bit being set to 1 is as follows: when 1 is written to the dte bit after the dte bit is read as 0 bit 6?data transfer enable 1 (dte1): enables or disables data transfer on channel 1. bit 6 dte1 description 0 data transfer disabled (initial value) 1

interrupt, rewrite the channel on which the transfer ended using a dtc chain transfer, and reactivate the dtc. dmawer applies restrictions so that specific bits of dmacr for the specific channel, and also dmatcr and dmabcr, can be changed to prevent inadvertent rewriting of registers other than those for the channel concerned. the restrictions applied by dmawer are valid for the dtc. figure 7-2 shows the transfer areas for activating the dtc with a channel 0a transfer end interrupt, and reactivating channel 0a. the address register and count register area is re-set by the first dtc transfer, then the control register area is re-set by the second dtc chain transfer. when re-setting the control register area, perform masking by setting bits in dmawer to prevent modification of the contents of the other channels. dtc mar0a ioar0a etcr0a mar0b ioar0b etcr0b mar1a ioar1a etcr1a mar1b ioar1b etcr1b dmatcr dmacr0b dmacr1b dmawer dmacr0a dmacr1a dmabcr second transfer area using chain

(1) sequential mode in response to a single transfer request, the specified number of transfers are carried out, one byte or one word at a time. an interrupt request can be sent to the cpu or dtc when the specified number of transfers have been completed. one address is specified as 24 bits, and the other as 16 bits. the transfer direction is programmable. (2) idle mode in response to a single transfer request, the specified number of transfers are carried out, one byte or one word at a time. an interrupt request can be sent to the cpu or dtc when the specified number of transfers have been completed. one address is specified as 24 bits, and the other as 16 bits. the transfer source address and transfer destination address are fixed. the transfer direction is programmable. (3) repeat mode in response to a single transfer request, the specified number of transfers are carried out, one byte or one word at a time. when the specified number of transfers have been completed, the addresses and transfer counter are restored to their original settings, and operation is continued. no interrupt request is sent to the cpu or dtc. one address is specified as 24 bits, and the other as 16 bits. the transfer direction is programmable. (4) single address mode in response to a single transfer request, the specified number of transfers are carried out between external memory and an external device, one byte or one word at a time. unlike dual address mode, source and destination accesses are performed in parallel. therefore, either the source or the destination is an external device which can be accessed with a strobe alone, using the dack pin. one address is specified as 24 bits, and for the other, the pin is set automatically. the transfer direction is programmable. modes (1), (2) and (3) can also be specified for single address mode. (5) normal mode auto-request by means of register settings only, the dmac is activated, and transfer continues until the specified number of transfers have been completed. an interrupt request can be sent to the cpu or dtc when transfer is completed. both addresses are specified as 24 bits. ? cycle steal mode: the bus is released to another bus master every byte or word transfer. ? burst mode: the bus is held and transfer continued until the specified number of transfers have been completed. external request in response to a single transfer request, the specified number of transfers are carried out, one byte or one word at a time. an interrupt request can be sent to the cpu or dtc when the specified number of transfers have been completed. both addresses are specified as 24 bits. (6) block transfer mode in response to a single transfer request, a block transfer of the specified block size is carried out. this is repeated the specified number of times, once each time there is a transfer request. at the end of each single block transfer, one address is restored to its original setting. an interrupt request can be sent to the cpu or dtc when the specified number of block transfers have been completed. both addresses are specified as 24 bits. rev.6.00 oct.28.2004 page 196 of 1016 rej09b0138-0600h 7.5.2 sequential mode sequential mode can be specified by clearing the rpe bit in dmacr to 0. in sequential mode, mar is updated after each byte or word transfer in response to a single transfer request, and this is executed the number of times specified in etcr. one address is specified by mar, and the other by ioar. the transfer direction can be specified by the dtdir bit in dmacr. table 7-6 summarizes register functions in sequential mode. table 7-6 register functions in sequential mode function register dtdir = 0 dtdir = 1 initial setting operation 23 0 mar source address register destination address register start address of transfer destination or transfer source incremented/ decremented every transfer 23 0 ioar 15 h'ff destination address register source address register start address of transfer source or transfer destination fixed 0 15 etcr transfer counter number of transfers decremented every transfer; transfer ends when count reaches h'0000 legend: mar: memory address register ioar: i/o address register etcr: transfer count register dtdir:data transfer direction bit mar specifies the start address of the transfer source or transfer destination as 24 bits. mar is incremented or decremented by 1 or 2 each time a byte or word is transferred. ioar specifies the lower 16 bits of the other address. the 8 bits above ioar have a value of h'ff. rev.6.00 oct.28.2004 page 197 of 1016 rej09b0138-0600h figure 7-3 illustrates operation in sequential mode. address t address b transfer ioar 1 byte or word transfer performed in response to 1 transfer request legend: address t = l address b = l + (?) dtid ?(2 dtsz ?(n?)) where : l = value set in mar n = value set in etcr figure 7-3 operation in sequential mode the number of transfers is specified as 16 bits in etcr. etcr is decremented by 1 each time a transfer is executed, and when its value reaches h'0000, the dte bit is cleared and transfer ends. if the dtie bit is set to 1 at this time, an interrupt request is sent to the cpu or dtc. the maximum number of transfers, when h'0000 is set in etcr, is 65,536. transfer requests (activation sources) consist of a/d converter conversion end interrupts, external requests, sci transmission data empty and reception data full interrupts, and tpu channel 0 to 5 compare match/input capture a interrupts. external requests can be set for channel b only. rev.6.00 oct.28.2004 page 198 of 1016 rej09b0138-0600h figure 7-4 shows an example of the setting procedure for sequential mode. sequential mode setting set dmabcrh set transfer source and transfer destination addresses set number of transfers set dmacr read dmabcrl set dmabcrl sequential mode [1] [2] [3] [4] [5] [6] [1] set each bit in dmabcrh. clear the fae bit to 0 to select short address mode. specify enabling or disabling of internal interrupt clearing with the dta bit.

and auto-requests. the activation sources that can be specified depend on the transfer mode and the channel, as shown in table 7-12. table 7-12 dmac activation sources short address mode full address mode activation source channels 0a and 1a channels 0b and 1b normal mode block transfer mode internal adi interrupts txi0 rxi0 txi1 rxi1 tgi0a tgi1a tgi2a tgi3a tgi4a tgi5a external dreq pin falling edge input requests dreq pin low-level input auto-request legend: : can be specified : cannot be specified activation by internal interrupt: an interrupt request selected as a dmac activation source can be sent simultaneously to the cpu and dtc. for details, see section 5, interrupt controller. with activation by an internal interrupt, the dmac accepts the request independently of the interrupt controller. consequently, interrupt controller priority settings are not accepted. if the dmac is activated by a cpu interrupt source or an interrupt source that is not used as a dtc activation source (dta = 1), the interrupt source flag is cleared automatically by the dma transfer. with adi, txi, and rxi interrupts, however, the interrupt source flag is not cleared unless the prescribed register is accessed in a dma transfer. if the same interrupt is used as an activation source for more than one channel, the interrupt request flag is cleared when the highest- priority channel is activated first. transfer requests for other channels are held pending in the dmac, and activation is carried out in order of priority. when dte = 0, such as after completion of a transfer, a request from the selected activation source is not sent to the dmac, regardless of the dta bit. in this case, the relevant interrupt request is sent to the cpu or dtc. in case of overlap with a cpu interrupt source or dtc activation source (dta = 0), the interrupt request flag is not cleared by the dmac. rev.6.00 oct.28.2004 page 216 of 1016 rej09b0138-0600h activation by external request: if an external request ( dreq pin) is specified as an activation source, the relevant port should be set to input mode in advance. level sensing or edge sensing can be used for external requests. external request operation in normal mode (short address mode or full address mode) is described below. when edge sensing is selected, a 1-byte or 1-word transfer is executed each time a high-to-low transition is detected on the dreq pin. the next transfer may not be performed if the next edge is input before transfer is completed. when level sensing is selected, the dmac stands by for a transfer request while the dreq pin is held high. while the dreq pin is held low, transfers continue in succession, with the bus being released each time a byte or word is transferred. if the dreq pin goes high in the middle of a transfer, the transfer is interrupted and the dmac stands by for a transfer request. activation by auto-request: auto-request activation is performed by register setting only, and transfer continues to the end. with auto-request activation, cycle steal mode or burst mode can be selected. in cycle steal mode, the dmac releases the bus to another bus master each time a byte or word is transferred. dma and cpu cycles usually alternate. in burst mode, the dmac keeps possession of the bus until the end of the transfer, and transfer is performed continuously. single address mode: the dmac can operate in dual address mode in which read cycles and write cycles are separate cycles, or single address mode in which read and write cycles are executed in parallel. in dual address mode, transfer is performed with the source address and destination address specified separately. in single address mode, on the other hand, transfer is performed between external space in which either the transfer source or the transfer destination is specified by an address, and an external device for which selection is performed by means of the dack strobe, without regard to the address. figure 7-17 shows the data bus in single address mode. external memory external device (read) (write) rd hwr , lwr a 23 to a 0 h8s/2357 group d 15 to d 0 (high impedance) dack address bus data bus figure 7-17 data bus in single address mode rev.6.00 oct.28.2004 page 217 of 1016 rej09b0138-0600h when using the dmac for single address mode reading, transfer is performed from external memory to the external device, and the dack pin functions as a write strobe for the external device. when using the dmac for single address mode writing, transfer is performed from the external device to external memory, and the dack pin functions as a read strobe for the external device. since there is no directional control for the external device, one or other of the above single directions should be used. bus cycles in single address mode are in accordance with the settings of the bus controller for the external memory area. on the external device side, dack is output in synchronization with the address strobe. for details of bus cycles, see section 7.5.11, dmac bus cycles (single address mode). do not specify internal space for transfer addresses in single address mode. 7.5.9 basic dmac bus cycles an example of the basic dmac bus cycle timing is shown in figure 7-18. in this example, word-size transfer is performed from 16-bit, 2-state access space to 8-bit, 3-state access space. when the bus is transferred from the cpu to the dmac, a source address read and destination address write are performed. the bus is not released in response to another bus request, etc., between these read and write operations. as with cpu cycles, dma cycles conform to the bus controller settings. address bus dmac cycle (1-word transfer) rd lwr hwr source address destination address cpu cycle cpu cycle t 1 t 2 t 3 t 1 t 2 t 3 t

mode, one-byte or one-word transfers are executed consecutively until transfer ends. in the transfer end cycle (the cycle in which the transfer counter reaches 0), a one-state dma dead cycle is inserted after the dma write cycle. if a request from another higher-priority channel is generated after burst transfer starts, that channel has to wait until the burst transfer ends. if an nmi is generated while a channel designated for burst transfer is in the transfer enabled state, the dtme bit is cleared and the channel is placed in the transfer disabled state. if burst transfer has already been activated inside the dmac, the bus is released on completion of a one-byte or one-word transfer within the burst transfer, and burst transfer is suspended. if the last transfer cycle of the burst transfer has already been activated inside the dmac, execution continues to the end of the transfer even if the dtme bit is cleared. rev.6.00 oct.28.2004 page 221 of 1016 rej09b0138-0600h

executed at high speed using the write data buffer function, enabling system throughput to be improved. when the wdbe bit of bcrl in the bus controller is set to 1, enabling the write data buffer function, dual address transfer external write cycles or single address transfers and internal accesses (on-chip memory or internal i/o registers) are executed in parallel. internal accesses are independent of the bus master, and dmac dead cycles are regarded as internal accesses. a low level can always be output from the tend pin if the bus cycle in which a low level is to be output is an external bus cycle. however, a low level is not output from the tend pin if the bus cycle in which a low level is to be output from the tend pin is an internal bus cycle, and an external write cycle is executed in parallel with this cycle. figure 7-33 shows an example of burst mode transfer from on-chip ram to external memory using the write data buffer function. internal address internal read

transfer, when the bus is released the dmac selects the highest-priority channel from among those issuing a request according to the priority order shown in table 7-13. during burst transfer, or when one block is being transferred in block transfer, the channel will not be changed until the end of the transfer. figure 7-35 shows a transfer example in which transfer requests are issued

between a dma cycle read and a dma cycle write. this means that a refresh cycle, external bus release cycle, or dtc cycle is not generated between the external read and external write in a dma cycle. in the case of successive read and write cycles, such as in burst transfer or block transfer, a refresh or external bus release d state may be inserted after a write cycle. since the dtc has a lower priority than the dmac, the dtc does not operate until the dmac releases the bus. when dma cycle reads or writes are accesses to on-chip memory or internal i/o registers, these dma cycles can be executed at the same time as refresh cycles or external bus release. however, simultaneous operation may not be possible when a write buffer is used. rev.6.00 oct.28.2004 page 233 of 1016 rej09b0138-0600h 7.5.15 nmi interrupts and dmac when an nmi interrupt is requested, burst mode transfer in full address mode is interrupted. an nmi interrupt does not affect the operation of the dmac in other modes. in full address mode, transfer is enabled for a channel when both the dte bit and the dtme bit are set to 1. with burst mode setting, the dtme bit is cleared when an nmi interrupt is requested. if the dtme bit is cleared during burst mode transfer, the dmac discontinues transfer on completion of the 1-byte or 1- word transfer in progress, then releases the bus, which passes to the cpu. the channel on which transfer was interrupted can be restarted by setting the dtme bit to 1 again. figure 7-36 shows the procedure for continuing transfer when it has been interrupted by an nmi interrupt on a channel designated for burst mode transfer. resumption of transfer on interrupted channel set dtme bit to 1 transfer continues [1] [2] dte = 1 dtme = 0 transfer ends no yes [1] [2]

(a) dmac control starts one cycle before the bus cycle, with output of the internal address. consequently, mar is updated in the bus cycle before dmac transfer. figure 7-40 shows an example of the update timing for dmac registers in dual address transfer mode.

(a) write data buffer function and dmac register setting if the setting of is changed during execution of an external access by means of the write data buffer function, the external access may not be performed normally. the register that controls external accesses should only be manipulated when external reads, etc., are used with dmac operation disabled, and the operation is not performed in parallel with external access. rev.6.00 oct.28.2004 page 239 of 1016 rej09b0138-0600h (b) write data buffer function and dmac operation timing the dmac can start its next operation during external access using the write data buffer function. consequently, the dreq pin sampling timing, tend output timing, etc., are different from the case in which the write data buffer function is disabled. also, internal bus cycles maybe hidden, and not visible. (c) write data buffer function and tend output a low level is not output from the tend pin if the bus cycle in which a low level is to be output from the tend pin is an internal bus cycle, and an external write cycle is executed in parallel with this cycle. note, for example, that a low level may not be output from the tend pin if the write data buffer function is used when data transfer is performed between an internal i/o register and on-chip memory. if at least one of the dmac transfer addresses is an external address, a low level is output from the tend pin. figure 7-42 shows an example in which a low level is not output at the tend pin. internal address internal read signal external address hwr , lwr internal write signal tend not output dma read external write by cpu, etc. dma write figure 7-42 example in which low level is not output at tend pin activation by falling edge on dreq pin: dreq pin falling edge detection is performed in synchronization with dmac internal operations. the operation is as follows: [1] activation request wait state: waits for detection of a low level on the dreq pin, and switches to [2]. [2] transfer wait state: waits for dmac data transfer to become possible, and switches to [3]. [3] activation request disabled state: waits for detection of a high level on the dreq pin, and switches to [1]. after dmac transfer is enabled, a transition is made to [1]. thus, initial activation after transfer is enabled is performed by detection of a low level. activation source acceptance: at the start of activation source acceptance, a low level is detected in both dreq pin falling edge sensing and low level sensing. similarly, in the case of an internal interrupt, the interrupt request is detected . therefore, a request is accepted from an internal interrupt or dreq pin low level that occurs before execution of the dmabcrl write to enable transfer. rev.6.00 oct.28.2004 page 240 of 1016 rej09b0138-0600h when the dmac is activated, take any necessary steps to prevent an internal interrupt or dreq pin low level remaining from the end of the previous transfer, etc. internal interrupt after end of transfer: when the dte bit is cleared to 0 by the end of transfer or an abort, the selected internal interrupt request will be sent to the cpu or dtc even if dta is set to 1. also, if internal dmac activation has already been initiated when operation is aborted, the transfer is executed but flag clearing is not performed for the selected internal interrupt even if dta is set to 1. an internal interrupt request following the end of transfer or an abort should be handled by the cpu as necessary. channel re-setting: to reactivate a number of channels when multiple channels are enabled, use exclusive handling of transfer end interrupts, and perform dmabcr control bit operations exclusively. note, in particular, that in cases where multiple interrupts are generated between reading and writing of dmabcr, and a dmabcr operation is performed during new interrupt handling, the dmabcr write data in the original interrupt handling routine will be incorrect, and the write may invalidate the results of the operations by the multiple interrupts. ensure that overlapping dmabcr operations are not performed by multiple interrupts, and that there is no separation between read and write operations by the use of a bit-manipulation instruction. also, when the dte and dtme bits are cleared by the dmac or are written with 0, they must first be read while cleared to 0 before the cpu can write 1 to them. rev.6.00 oct.28.2004 page 241 of 1016 rej09b0138-0600h

information. after the data transfer, it writes updated register information back to memory. pre-storage of register information in memory makes it possible to transfer data over any required number of channels. setting the chne bit to 1 makes it possible to perform a number of transfers with a single activation. figure 8-2 shows a flowchart of dtc operation. start read dtc vector next transfer

write to dtvecr by software. an interrupt request can be directed to the cpu or dtc, as designated by the corresponding dtcer bit. an interrupt becomes a dtc activation source when the corresponding bit is set to 1, and a cpu interrupt source when the bit is cleared to 0. at the end of a data transfer (or the last consecutive transfer in the case of chain transfer), the activation source or corresponding dtcer bit is cleared. table 8-3 shows activation source and dtcer clearance. the activation source flag, in the case of rxi0, for example, is the rdrf flag of sci0. table 8-3 activation

default priorities. rev.6.00 oct.28.2004 page 252 of 1016 rej09b0138-0600h 8.3.3 dtc vector table figure 8-4 shows the correspondence between dtc vector addresses and register information. table 8-4 shows the correspondence between activation, vector addresses, and dtcer bits. when the dtc is activated by software, the vector address is obtained from: h'0400 + (dtvecr[6:0] <<1) (where << 1 indicates a 1-bit left shift). for example, if dtvecr is h'10, the vector address is h'0420. the dtc reads the start address of the register information from the vector address set for each activation source, and then reads the register information from that start address. the register information can be placed at predetermined addresses in the on-chip ram. the start address of the register information should be an integral multiple of four. the configuration of the vector address is the same in both normal and advanced modes, a 2-byte unit being used in both cases. these two bytes specify the lower bits of the address in the on-chip ram. rev.6.00 oct.28.2004 page 253 of 1016 rej09b0138-0600h table 8-4 interrupt sources, dtc vector addresses, and corresponding dtces interrupt

s m for example, when the dtc vector address table is located in on-chip rom, normal mode is set, and data is transferred from the on-chip rom to an internal i/o register, the time required for the dtc operation is 13 states. the time from activation to the end of the data write is 10 states. 8.3.11 procedures for using dtc activation by interrupt: the procedure for using the dtc with interrupt activation is as follows: [1] set the mra, mrb, sar, dar, cra, and crb register information in the on-chip ram. [2] set the start address of the register information in the dtc vector address. [3] set the corresponding bit in dtcer to 1. [4] set the enable bits for the interrupt sources to be used as the activation sources to 1. the dtc is activated when an interrupt used as an activation source is generated. [5] after the end of one data transfer, or after the specified number of data transfers have ended, the dtce bit is cleared to 0 and a cpu interrupt is requested. if the dtc is to continue transferring data, set the dtce bit to 1. activation by software: the procedure for using the dtc with software activation is as follows: [1] set the mra, mrb, sar, dar, cra, and crb register information in the on-chip ram. [2] set the start address of the register information in the dtc vector address. [3] check that the swdte bit is 0. [4] write 1 to swdte bit and the vector number to dtvecr. [5] check the vector number written to dtvecr. [6] after the end of one data transfer, if the disel bit is 0 and a cpu interrupt is not requested, the swdte bit is cleared to 0. if the dtc is to continue transferring data, set the swdte bit to 1. when the disel bit is 1, or after the specified number of data transfers have ended, the swdte bit is held at 1 and a cpu interrupt is requested. 8.3.12 examples of use of the d7tc (1) normal mode an example is shown in which the dtc is used to receive 128 bytes of data via the sci. [1] set mra to fixed source address (sm1 = sm0 = 0), incrementing destination address (dm1 = 1, dm0 = 0), normal mode (md1 = md0 = 0), and byte size (sz = 0). the dts bit can have any value. set mrb for one data transfer by one interrupt (chne = 0, disel = 0). set the sci rdr address in sar, the start address of the ram area where the data will be received in dar, and 128 (h'0080) in cra. crb can be set to any value. [2] set the start address of the register information at the dtc vector address. [3] set the corresponding bit in dtcer to 1. rev.6.00 oct.28.2004 page 263 of 1016 rej09b0138-0600h [4] set the sci to the appropriate receive mode. set the rie bit in scr to 1 to enable the reception data full (rxi) interrupt. since the generation of a receive error during the sci reception operation will disable subsequent reception, the cpu should be enabled to accept receive error interrupts. [5] each time reception of one byte of data ends on the sci, the rdrf flag in ssr is set to 1, an rxi interrupt is generated, and the dtc is activated. the receive data is transferred from rdr to ram by the dtc. dar is incremented and cra is decremented. the rdrf flag is automatically cleared to 0. [6] when cra becomes 0 after the 128 data transfers have ended, the rdrf flag is held at 1, the dtce bit is cleared to 0, and an rxi interrupt request is sent to the cpu. the interrupt handling routine should perform wrap-up processing. (2) chain transfer an example of dtc chain transfer is shown in which pulse output is performed using the ppg. chain transfer can be used to perform pulse output data transfer and ppg output trigger cycle updating. repeat mode transfer to the ppg?s ndr is performed in the first half of the chain transfer, and normal mode transfer to the tpu?s tgr in the second half. this is because clearing of the activation source and interrupt generation at the end of the specified number of transfers are restricted to the second half of the chain transfer (transfer when chne = 0). [1] perform settings for transfer to the ppg?s ndr. set mra to source address incrementing (sm1 = 1, sm0 = 0), fixed destination address (dm1 = dm0 = 0), repeat mode (md1 = 0, md0 = 1), and word size (sz = 1). set the source side as a repeat area (dts = 1). set mrb to chain mode (chne = 1, disel = 0). set the data table start address in sar, the ndrh address in dar, and the data table size in crah and cral. crb can be set to any value. [2] perform settings for transfer to the tpu?s tgr. set mra to source address incrementing (sm1 = 1, sm0 = 0), fixed destination address (dm1 = dm0 = 0), normal mode (md1 = md0 = 0), and word size (sz = 1). set the data table start address in sar, the tgra address in dar, and the data table size in cra. crb can be set to any value. [3] locate the tpu transfer register information consecutively after the ndr transfer register information. [4] set the start address of the ndr transfer register information to the dtc vector address. [5] set the bit corresponding to tgia in dtcer to 1. [6] set tgra as an output compare register (output disabled) with tior, and enable the tgia interrupt with tier. [7] set the initial output value in podr, and the next output value in ndr. set bits in ddr and nder for which output is to be performed to 1. using pcr, select the tpu compare match to be used as the output trigger. [8] set the cst bit in tstr to 1, and start the tcnt count operation. [9] each time a tgra compare match occurs, the next output value is transferred to ndr and the set value of the next output trigger period is transferred to tgra. the activation source tgfa flag is cleared. [10] when the specified number of transfers are completed (the tpu transfer cra value is 0), the tgfa flag is held at 1, the dtce bit is cleared to 0, and a tgia interrupt request is sent to the cpu. termination processing should be performed in the interrupt handling routine. (3) software activation an example is shown in which the dtc is used to transfer a block of 128 bytes of data by means of software activation. the transfer source address is h'1000 and the destination address is h'2000. the vector number is h'60, so the vector address is h'04c0. rev.6.00 oct.28.2004 page 264 of 1016 rej09b0138-0600h [1] set mra to incrementing source address (sm1 = 1, sm0 = 0), incrementing destination address (dm1 = 1, dm0 = 0), block transfer mode (md1 = 1, md0 = 0), and byte size (sz = 0). the dts bit can have any value. set mrb for one block transfer by one interrupt (chne = 0). set the transfer source address (h'1000) in sar, the destination address (h'2000) in dar, and 128 (h'8080) in cra. set 1 (h'0001) in crb. [2] set the start address of the register information at the dtc vector address (h'04c0). [3] check that the swdte bit in dtvecr is 0. check that there is currently no transfer activated by software. [4] write 1 to the swdte bit and the vector number (h'60) to dtvecr. the write data is h'e0. [5] read dtvecr again and check that it is set to the vector number (h'60). if it is not, this indicates that the write failed. this is presumably because an interrupt occurred between steps 3 and 4 and led to a different software activation. to activate this transfer, go back to step 3. [6] if the write was successful, the dtc is activated and a block of 128 bytes of data is transferred. [7] after the transfer, an swdtend interrupt occurs. the interrupt handling routine should clear the swdte bit to 0 and perform other wrap-up processing. 8.4 interrupts an interrupt request is issued to the cpu when the dtc finishes the specified number of data transfers, or a data transfer for which the disel bit was set to 1. in the case of interrupt activation, the interrupt set as the activation source is generated. these interrupts to the cpu are subject to cpu mask level and interrupt controller priority level control. in the case of activation by software, a software activated data transfer end interrupt (swdtend) is generated. when the disel bit is 1 and one data transfer has ended, or the specified number of transfers have ended, after data transfer ends, the swdte bit is held at 1 and an swdtend interrupt is generated. the interrupt handling routine should clear the swdte bit to 0. when the dtc is activated by software, an swdtend interrupt is not generated during a data transfer wait or during data transfer even if the swdte bit is set to 1. 8.5 usage notes module stop: when the mstp14 bit in mstpcr is set to 1, the dtc clock stops, and the dtc enters the module stop state. however, 1 cannot be written in the mstp14 bit while the dtc is operating. on-chip ram: the mra, mrb, sar, dar, cra, and crb registers are all located in on-chip ram. when the dtc is used, the rame bit in syscr must not be cleared to 0. dmac transfer end interrupt: when dtc transfer is activated by a dmac transfer end interrupt, regardless of the transfer counter and disel bit, the dmac?s dte bit is not subject to dtc control, and the write data has priority. consequently, an interrupt request may not be sent to the cpu when the dtc transfer counter reaches 0. dtce bit setting: for dtce bit setting, read/write operations must be performed using bit-manipulation instructions such as bset and bclr. for the initial setting only, however, when multiple activation sources are set at one time, it is possible to disable interrupts and write after executing a dummy read on the relevant register. rev.6.00 oct.28.2004 page 265 of 1016 rej09b0138-0600h section 9 i/o ports 9.1 overview the h8s/2357 group has 12 i/o ports (ports 1, 2, 3, 5, 6, and a to g), and one input-only port (port 4). table 9-1 summarizes the port functions. the pins of each port also have other functions. each port includes a data direction register (ddr) that controls input/output (not provided for the input-only port), a data register (dr) that stores output data, and a port register (port) used to read the pin states. ports a to e have a on-chip pull-up mos function, and in addition to dr and ddr, have a mos input pull-up control register (pcr) to control the on/off state of mos input pull-up. port 3 and port a include an open-drain control register (odr) that controls the on/off state of the output buffer pmos. ports 1, and a to f can drive a single ttl load and 90 pf capacitive load, and ports 2, 3, 5, 6, and g can drive a single ttl load and 30 pf capacitive load. all the i/o ports can drive a darlington transistor when in output mode. ports 1, a, b, and c can drive an led (10 ma sink current). port 2, and pins 6 4 to 6 7 and a 4 to a 7 , are schmitt-triggered inputs. for block diagrams of the ports see appendix c, i/o port block diagrams. rev.6.00

operation 10.4.1 overview operation in each mode is outlined below. normal operation: each channel has a tcnt and tgr register. tcnt performs up-counting, and is also capable of free-running operation, synchronous counting, and external event counting. each tgr can be used as an input capture register or output compare register. synchronous operation: when synchronous operation is designated for a channel, tcnt for that channel performs synchronous presetting. that is, when tcnt for a channel designated for synchronous operation is rewritten, the tcnt counters for the other channels are also rewritten at the same time. synchronous clearing of the tcnt counters is also possible by setting the timer synchronization bits in tsyr for channels designated for synchronous operation. buffer operation ? when tgr is an output compare register when a compare match occurs, the value in the buffer register for the relevant channel is transferred to tgr. ? when tgr is an input capture register when input capture occurs, the value in tcnt is transfer to tgr and the value previously held in tgr is transferred to the buffer register. cascaded operation: the channel 1 counter (tcnt1), channel 2 counter (tcnt2), channel 4 counter (tcnt4), and channel 5 counter (tcnt5) can be connected together to operate as a 32-bit counter. pwm mode: in this mode, a pwm waveform is output. the output level can be set by means of tior. a pwm waveform with a duty of between 0% and 100% can be output, according to the setting of each tgr register. phase counting mode: in this mode, tcnt is incremented or decremented by detecting the phases of two clocks input from the external clock input pins in channels 1, 2, 4, and 5. when phase counting mode is set, the corresponding tclk pin functions as the clock pin, and tcnt performs up- or down-counting. this can be used for two-phase encoder pulse input. rev.6.00 oct.28.2004 page 372 of 1016 rej09b0138-0600h 10.4.2 basic functions counter operation: when one of bits cst0 to cst5 is set to 1 in tstr, the tcnt counter for the corresponding channel starts counting. tcnt can operate as a free-running counter, periodic counter, and so on. ? example of count operation setting procedure figure 10-6 shows an example of the count operation setting procedure. select counter clock operation selection select counter

reset, the tpu? tcnt counters are all designated as free-running counters. 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 tpu requests an interrupt. after overflow, tcnt starts counting up again from h'0000. figure 10-7 illustrates free-running counter operation. tcnt value h'ffff h'0000 cst bit tcfv time figure 10-7 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 cclr2 to cclr0 in tcr. after the settings have been made, tcnt starts up-count operation as 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 tpu requests an interrupt. after a compare match, tcnt starts counting up again from h'0000. figure 10-8 illustrates periodic counter operation. tcnt value tgr h'0000 cst bit

function works by counting the channel 1 (channel 4) counter clock upon overflow/underflow of tcnt2 (tcnt5) as set in bits tpsc2 to tpsc0 in tcr. underflow occurs only when the lower 16-bit tcnt is in phase-counting mode. table 10-6 shows the register combinations used in cascaded operation. note: when phase counting mode is set for channel 1 or 4, the counter clock setting is invalid and the counter operates independently in phase counting mode. table 10-6 cascaded combinations combination upper 16 bits lower 16 bits channels 1 and 2 tcnt1 tcnt2 channels 4 and 5 tcnt4 tcnt5 example of

mode, pwm waveforms are output from the output pins. 0, 1, or toggle output can be selected as the output level in response to compare match of each tgr. 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 rev.6.00 oct.28.2004 page 384 of 1016 rej09b0138-0600h pwm output is generated from the tioca and tiocc pins by pairing tgra with tgrb and tgrc with tgrd. the output specified by bits ioa3 to ioa0 and ioc3 to ioc0 in tior is output from the tioca and tiocc pins at compare matches a and c, and the output specified by bits iob3 to iob0 and iod3 to iod0 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 15-phase pwm output is possible by combined use with synchronous operation. the correspondence between pwm output pins and registers is shown in table 10-7. table 10-7 pwm output registers and output pins output pins channel registers pwm mode 1 pwm mode 2 0 tgr0a tioca0 tioca0

rev.6.00 oct.28.2004 page 388 of 1016 rej09b0138-0600h 10.4.7 phase counting mode in phase counting mode, the phase difference between two external clock inputs is detected and tcnt is incremented/decremented accordingly. this mode can be set for channels 1, 2, 4, and 5. 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 tpsc2 to tpsc0 and bits ckeg1 and ckeg0 in tcr. however, the functions of bits cclr1 and cclr0 in tcr, and of tior, tier, and tgr are valid, and input capture/compare match and interrupt functions can be used. when overflow occurs while tcnt is counting up, the tcfv flag in tsr is set; when underflow occurs while tcnt is counting down, the tcfu flag is set. the tcfd bit in tsr is the count direction flag. reading the tcfd flag provides an indication of whether tcnt is counting up or down. table 10-8 shows the correspondence between external clock pins and channels. table 10-8 phase counting mode clock input pins external clock pins channels a-phase b-phase when channel 1 or 5 is set to phase counting mode tclka tclkb when channel 2 or 4 is set

function, and are set with the speed control period and position control period. tgr0b is used for input capture, with tgr0b and tgr0d operating in buffer mode. the channel 1 counter input clock is designated as the tgr0b input capture source, and detection of the pulse width of 2-phase encoder 4-multiplication pulses is performed. tgr1a and tgr1b for channel 1 are designated for input capture, channel 0 tgr0a and tgr0c compare matches are selected as the input capture source, and store the up/down-counter values for the control periods. this procedure enables accurate position/speed

tcnt underflow. each interrupt source has its own status flag and enable/disabled bit, allowing 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 th e status flag to 0. relative channel priorities can be changed by the interrupt controller, but the priority order within a channel is fixed. for details, see section 5, interrupt controller. table 10-13 lists the tpu interrupt sources. rev.6.00 oct.28.2004 page 395 of 1016 rej09b0138-0600h table 10-13 tpu interrupts channel interrupt source description dmac

in tier is set to 1 when the tgf flag in tsr is set to 1 by the occurrence of a tgr input capture/compare match on a particular channel. the interrupt request is cleared by clearing the tgf flag to 0. the tpu has 16 input capture/compare match interrupts, four each for channels 0 and 3, and two each for channels 1, 2, 4, and 5. 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 tpu has six overflow interrupts, one for each channel. 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 tpu has four underflow interrupts, one each for channels 1, 2, 4, and 5. 10.5.2 dtc/dmac activation dtc activation: the dtc can be activated by the tgr input capture/compare match interrupt for a channel. for details, see section 8, data transfer controller. a total of 16 tpu input capture/compare match interrupts can be used as dtc activation sources, four each for channels 0 and 3, and two each for channels 1, 2, 4, and 5. dmac activation: the dmac can be activated by the tgra input capture/compare match interrupt for a channel. for details, see section 7, dma controller. in the tpu, a total of six tgra input capture/compare match interrupts can be used as dmac activation sources, one for each channel. 10.5.3 a/d converter activation the a/d converter can be activated by the tgra input capture/compare match for a channel. if the ttge bit in tier is set to 1 when the tgfa flag in tsr is set to 1 by the occurrence of a tgra input capture/compare match on a particular channel, a request to start a/d conversion is sent to the a/d converter. if the tpu conversion start trigger has been selected on the a/d converter side at this time, a/d conversion is started. in the tpu, a total of six tgra input capture/compare match interrupts can be used as a/d converter conversion start sources, one for each

11.1 overview the h8s/2357 group has a on-chip programmable pulse generator (ppg) that provides pulse outputs by using the 16-bit timer-pulse unit (tpu) as a time base. the ppg pulse outputs are divided into 4-bit groups (group 3 to group 0) that can operate both simultaneously and independently. 11.1.1 features ppg features are listed below. ? 16-bit output data ? maximum 16-bit data can be output, and output can be enabled on a bit-by-bit basis ? four output groups ? output trigger signals can be selected in 4-bit groups to provide up to four different 4-bit outputs ? selectable output trigger signals ? output trigger signals can be selected for each group from the compare match signals of four tpu channels ? non-overlap mode ? a non-overlap margin can be provided between pulse outputs ? can operate together with the data transfer controller (dtc) and dma controller (dmac) ? the compare match signals selected as output trigger signals can activate the dtc or dmac for sequential output of data without cpu intervention ? settable inverted output ? inverted data can be output for each group ? module stop mode can be set ? as the initial setting, ppg operation is halted. register access is enabled by exiting module stop mode rev.6.00 oct.28.2004 page 412 of 1016 rej09b0138-0600h 11.1.2 block diagram figure 11-1 shows a block diagram of the ppg. compare match

are also used for other peripheral functions such as the tpu. when output by another peripheral function is enabled, the corresponding pins cannot be used for pulse output. note, however, that data transfer from ndr bits to podr bits takes place, regardless of the usage of the pins. pin functions should be changed only under conditions in which the output trigger event will not occur. note on non-overlapping output: during non-overlapping operation, the transfer of ndr bit values to podr bits takes place as follows. ? ndr bits are always transferred to podr bits at compare match a. ? at compare match b, ndr bits are transferred only if their value is 0. bits are not transferred if their value is 1. figure 11-10 illustrates the non-overlapping pulse output operation. compare match a

match b to compare match a (the non-overlap margin). this can be accomplished by having the tgia interrupt handling routine write the next data in ndr, or by having the tgia interrupt activate the dtc or dmac. note, however, that the next data must be written before the next compare match b occurs. figure 11-11 shows the timing of this operation. 0/1 output 0 output 0/1 output 0 output do not write

8-bit counter (tcnt) and two time constant registers (tcora and tcorb) that are constantly compared with the tcnt value to detect compare match events. the 8-bit timer module can thus be used for a variety of functions, including pulse output with an arbitrary duty cycle. 12.1.1 features the features of the 8-bit timer module are listed below. ? selection of four clock sources the counters can be driven by one of three internal clock signals (?8, ?64, or ?8192) or an external clock input (enabling use as an external event counter). ? selection of three ways to clear the counters the counters can be cleared on compare match a or b, or by an external reset signal. ? timer output control by a combination of two compare match signals the timer output signal in each channel is controlled by a combination of two independent compare match signals, enabling the timer to generate output waveforms with an arbitrary duty cycle or pwm output. ? provision for cascading of two channels ? operation as a 16-bit timer is possible, using channel 0 for the upper 8 bits and channel 1 for the lower 8 bits (16- bit count mode). ? channel 1 can be used to count channel 0 compare matches (compare match count mode). ? three independent interrupts compare match a and b and overflow interrupts can be requested independently. ? a/d converter conversion start trigger can be generated channel 0 compare match a signal can be used as an a/d converter conversion start trigger. ? module stop mode can be set ? as the initial setting, 8-bit timer operation is halted. register access is enabled by exiting module stop mode. rev.6.00 oct.28.2004 page 434 of 1016 rej09b0138-0600h 12.1.2 block diagram figure 12-1 shows a block diagram of the 8-bit timer module. external clock

a single 16-bit timer with channel 0 occupying the upper 8 bits and channel 1 occupying the lower 8 bits. ? setting of compare match flags ? the cmf flag in tcsr0 is set to 1 when a 16-bit compare match event occurs. ? the cmf flag in tcsr1 is set to 1 when a lower 8-bit compare match event occurs. ? counter clear specification ? if the cclr1 and cclr0 bits in tcr0 have been set for counter clear at compare match, the 16-bit counter (tcnt0 and tcnt1 together) is cleared when a 16-bit compare match event occurs. the 16-bit counter (tcnt0 and tcnt1 together) is cleared even if counter clear by the tmri0 pin has also been set. ? the settings of the cclr1 and cclr0 bits in tcr1 are ignored. the lower 8 bits cannot be cleared independently. ? pin output ? control of output from the tmo0 pin by bits os3 to os0 in tcsr0 is in accordance with the 16-bit compare match conditions. ? control of output from the tmo1 pin by bits os3 to os0 in tcsr1 is in accordance with the lower 8-bit compare match conditions. compare match counter mode: when bits cks2 to cks0 in tcr1 are b'100, tcnt1 counts compare match a? for channel 0. channels 0 and 1 are controlled independently. conditions such as setting of the cmf flag, generation of interrupts, output from the tmo pin, and counter clear are in accordance with the settings for each channel. note on usage: if the 16-bit counter mode and compare match counter mode are set simultaneously, the input clock pulses for tcnt0 and tcnt1 are not generated and thus the counters will stop operating. software should therefore avoid using both these modes. rev.6.00 oct.28.2004 page 446 of 1016 rej09b0138-0600h 12.4 interrupts 12.4.1 interrupt sources and dtc activation there are three 8-bit timer interrupt sources: cmia, cmib, and ovi. their relative priorities are shown in table 12-3. each interrupt source is set as enabled or disabled by the corresponding interrupt enable bit in tcr, and independent interrupt requests are sent for each to the interrupt controller. it is also possible to activate the dtc by means of cmia and cmib interrupts. table 12-3 8-bit timer interrupt sources channel interrupt source description dtc

activation the a/d converter can be activated only by channel 0 compare match a. if the adte bit in tcsr0 is set to 1 when the cmfa flag is set to 1 by the occurrence of channel 0 compare match a, a request to start a/d conversion is sent to the a/d converter. if the 8-bit timer conversion start trigger has been selected on the a/d converter side at this time, a/d conversion is started. rev.6.00 oct.28.2004 page 447 of 1016 rej09b0138-0600h 12.5 sample application in the example below, the 8-bit timer is used to generate a pulse output with a selected duty cycle, as shown in figure 12-9. the control bits are set as follows: [1] in tcr, bit cclr1 is cleared to 0 and bit cclr0 is set to 1 so that the timer counter is cleared when its value matches the constant in tcora. [2] in tcsr, bits os3 to os0 are set to b'0110, causing the output to change to 1 at a tcora compare match and to 0 at a tcorb compare match. with these settings, the 8-bit timer provides output of pulses at a rate determined by tcora with a pulse width determined by tcorb. no software intervention is required. tcnt h'ff counter clear tcora tcorb h'00 tmo figure 12-9 example of pulse output

12.6.5 switching of internal clocks and tcnt operation tcnt may increment erroneously when the internal clock is switched over. table 12-5 shows the relationship between the timing at which the internal clock is switched (by writing to the cks1 and cks0 bits) and the tcnt operation. when the tcnt clock is generated from an internal clock, the falling edge of the internal clock pulse is detected. if clock switching causes a change from high to low level, as shown in case 3 in table 12-5, a tcnt clock pulse is generated on the assumption that the switchover is a falling edge. this increments tcnt. the erroneous incrementation can also happen when switching between internal and external clocks. table 12-5 switching of internal clock and tcnt operation no. timing of switchover by

outputs an overflow signal ( wdtovf ) if a system crash prevents the cpu from writing to the timer counter, allowing it to overflow. at the same time, the wdt can also generate an internal reset signal for the h8s/2357 group. when this watchdog function is not needed, the wdt can be used as an interval timer. in interval timer operation, an interval timer interrupt is generated each time the counter overflows. 13.1.1 features wdt features are listed below. switchable between watchdog timer mode and interval timer mode wdtovf output when in watchdog timer mode* 1 if the counter overflows,

rej09b0138-0600h 13.2.4 notes on register access the watchdog timer? tcnt, tcsr, and rstcsr registers differ from other registers in being more difficult to write to. the procedures for writing to and reading these registers are given below. writing to tcnt and tcsr: these registers must be written to by a word transfer instruction. they cannot be written to with byte instructions. figure 13-2 shows the format of data written to tcnt and tcsr. tcnt and tcsr both have the same write address. for a write to tcnt, the upper byte of the written word must contain h'5a and the lower byte must contain the write data. for a write to tcsr, the upper byte of the written word must contain h'a5 and the lower byte must contain the write data. this transfers the write data from the lower byte to tcnt or tcsr. tcnt write tcsr write address: h'ffbc address: h'ffbc h'5a write data 15 8 7 0 h'a5 write data 15 8 7 0 figure 13-2 format of data written to tcnt and tcsr writing to rstcsr: rstcsr must be written to by word transfer instruction to address h'ffbe. it cannot be written to with byte instructions. figure 13-3 shows the format of data written to rstcsr. the method of writing 0 to the wovf bit differs from that for writing to the rste and rsts bits. to write 0 to the wovf bit, the write data must have h'a5 in the upper byte and h'00 in the lower byte. this clears the wovf bit to 0, but has no effect on the rste and rsts bits. to write to the rste and rsts bits, the upper byte must contain h'5a and the lower byte must contain the write data. this writes the values in bits 6 and 5 of the lower byte into the rste and rsts bits, but has no effect on the wovf bit. h'a5 h'00 15 8 7 0 h'5a write data 15 8 7 0 writing 0 to wovf bit writing to rste and rsts bits address: h'ffbe address: h'ffbe figure 13-3 format of data written to rstcsr reading tcnt, tcsr, and rstcsr: these registers are read in the same way as other registers. the read addresses are h'ffbc for tcsr, h'ffbd for tcnt, and h'ffbf for rstcsr. rev.6.00 oct.28.2004 page 460 of 1016 rej09b0138-0600h 13.3 operation 13.3.1 watchdog timer operation to use the wdt as a watchdog timer, set the wt/ it and tme bits to 1. software must prevent tcnt overflows by rewriting the tcnt value (normally be writing h'00) before overflows occurs. this ensures that tcnt does not overflow while the system is operating normally. if tcnt overflows without being rewritten because of a system crash or other error, the wdtovf signal* 1 is output. this is shown in figure 13-4. this wdtovf signal* 1 can be used to reset the system. the wdtovf signal* 1 is output for 132 states when rste = 1, and for 130 states when rste = 0. if tcnt overflows when 1 is set in the rste bit in rstcsr, a signal that resets the h8s/2357 group internally is generated at the same time as the wdtovf signal* 1 . this reset can be selected as a power-on reset or a manual reset* 2 , depending on the setting of the rsts bit in rstcsr. the internal reset signal is output for 518 states. if a reset caused by a signal input to the res pin occurs at the same time as a reset caused by a wdt overflow, the res pin reset has priority and the wovf bit in rstcsr is cleared to 0. notes: 1. in the f-ztat version, the h8s/2398, h8s/2394, h8s/2392, or h8s/2390, the wdtovf pin function is not available. 2. manual reset is only supported in the

register descriptions 14.2.1 receive shift register (rsr) bit:7 65 43 21 0 r/w:? ?? ?? ?? ? rsr is a register used to receive serial data. the sci sets serial data input from the rxd pin in rsr in the order received, starting with the lsb (bit 0), and converts it to parallel data. when one byte of data has been received, it is transferred to rdr automatically. rsr cannot be directly read or written to by the cpu. 14.2.2 receive data register (rdr) bit:7 65 43 21 0 initial value : 0 0 0 0 0 0 0 0 r/w:r rr rr rr r rdr is a register that stores received serial data. when the sci has received one byte of serial data, it transfers the received serial data from rsr to rdr where it is stored, and completes the receive operation. after this, rsr is receive-enabled. since rsr and rdr function as a double buffer in this way, enables continuous receive operations to be performed. rdr is a read-only register, and cannot be written to by the cpu. rdr is initialized to h'00 by a reset, and in standby mode or module stop mode. 14.2.3 transmit shift register (tsr) bit:7 65 43 21 0 r/w:? ?? ?? ?? ? tsr is a register used to transmit serial data. to perform serial data transmission, the sci first transfers transmit data from tdr to tsr, then sends the data to the txd pin starting with the lsb (bit 0). when transmission of one byte is completed, the next transmit data is transferred from tdr to tsr, and transmission started, automatically. however, data transfer from tdr to tsr is not performed if the tdre bit in ssr is set to 1. tsr cannot be directly read or written to by the cpu. rev.6.00 oct.28.2004 page 470 of 1016 rej09b0138-0600h 14.2.4 transmit data register (tdr) bit:7 65 43 21 0 initial value : 1 1 1 1 1 1 1 1 r/w : r/w r/w r/w r/w r/w r/w r/w r/w tdr is an 8-bit register that stores data for serial transmission. when the sci detects that tsr is empty, it transfers the transmit data written in tdr to tsr and starts serial transmission. continuous serial transmission can be carried out by writing the next transmit data to tdr during serial transmission of the data in tsr. tdr can be read or written to by the cpu at all times. tdr is initialized to h'ff by a reset, and in standby mode or module stop mode. 14.2.5 serial mode register (smr) bit:7 65 43 21 0 c/ a chr pe o/ e stop mp cks1 cks0 initial value : 0 0 0 0 0 0 0 0 r/w : r/w r/w r/w r/w r/w r/w r/w r/w smr is an 8-bit register used to set the sci?s serial transfer format and select the baud rate generator clock source. smr can be read or written to by the cpu at all times. smr is initialized to h'00 by a reset, and by putting the device in standby mode or module stop mode. in the h8s/2398, h8s/2394, h8s/2392, and h8s/2390, however, the value in smr is initialized to h'00 by a reset, or in hardware standby mode, but smr retains its current state when the device enters software standby mode or module stop mode. bit 7?communication mode (c/ a ): selects asynchronous mode or clocked synchronous mode as the sci operating mode. bit 7 c/ a description 0 asynchronous mode (initial value) 1 clocked synchronous mode bit 6?haracter length (chr): selects 7 or 8 bits as the data length in asynchronous mode. in clocked synchronous mode, a fixed data length of 8 bits is used regardless of the chr setting. bit 6 chr description 0 8-bit data (initial value) 1 7-bit data * note: * when 7-bit data is selected, the msb (bit 7) of tdr is not transmitted, and it is not possible to choose between lsb-first or msb-first transfer. rev.6.00 oct.28.2004 page 471 of 1016 rej09b0138-0600h bit 5?parity enable (pe): in asynchronous mode, selects whether or not parity bit addition is performed in transmission, and parity bit checking in reception. in clocked synchronous mode and with a multiprocessor format, parity bit addition and checking is not performed, regardless of the pe bit setting. bit 5 pe description 0 parity bit addition and checking disabled (initial value) 1 parity bit addition and checking enabled * note: * when the pe bit is set to 1, the parity (even or odd) specified by the o/ e bit is added to transmit data before transmission. in reception, the parity bit is checked for the parity (even or odd) specified by the o/ e bit. bit 4?parity mode (o/ e ): selects either even or odd parity for use in parity addition and checking. the o/ e bit setting is only valid when the pe bit is set to 1, enabling parity bit addition and checking, in asynchronous mode. the o/ e bit setting is invalid in clocked synchronous mode, and when parity addition and checking is disabled in asynchronous mode. bit 4 o/ e description 0 even parity * 1 (initial value) 1 odd parity * 2 notes: 1. when even parity is set, parity bit addition is performed in transmission so that the total number of 1 bits in the transmit character plus the parity bit is even. in reception, a check is performed to see if the total number of 1 bits in the receive character plus the parity bit is even. 2. when odd parity is set, parity bit addition is performed in transmission so that the total number of 1 bits in the transmit character plus the parity bit is odd. in reception, a check is performed to see if the total number of 1 bits in the receive character plus the parity bit is odd. bit 3?top bit length (stop): selects 1 or 2 bits as the stop bit length in asynchronous mode. the stop bits setting is only valid in asynchronous mode. if clocked synchronous mode is set the stop bit setting is invalid since stop bits are not added. bit 3 stop description 0 1 stop bit: in transmission, a single 1 bit (stop bit) is added to the end of a transmit character before it is sent. (initial value) 1 2 stop bits : in transmission, two 1 bits (stop bits) are added to the end of a transmit character before it is sent. in reception, only the first stop bit is checked, regardless of the stop bit setting. if the second stop bit is 1, it is treate d as a stop bit; if it is 0, it is treated as the start bit of the next transmit character. bit 2?ultiprocessor mode (mp): selects multiprocessor format. when multiprocessor format is selected, the pe bit and o/ e bit parity settings are invalid. the mp bit setting is only valid in asynchronous mode; it is invalid in clocked synchronous mode. rev.6.00 oct.28.2004 page 472 of 1016 rej09b0138-0600h for details of the multiprocessor communication function, see section 14.3.3, multiprocessor communication function. bit 2 mp

clock output in asynchronous mode, and interrupt requests, and selection of the serial clock source. scr can be read or written to by the cpu at all times. scr is initialized to h'00 by a reset, and by putting the device in standby mode or module stop mode. in the h8s/2398, h8s/2394, h8s/2392, and h8s/2390, however, the value in scr is initialized to h'00 by a reset, or in hardware standby mode, but scr retains its current state when the device enters software standby mode or module stop mode. bit 7?ransmit interrupt enable (tie): enables or disables transmit data empty interrupt (txi) request generation when serial transmit data is transferred from tdr to tsr and the tdre flag in ssr is set to 1. bit 7 tie description 0 transmit data empty interrupt (txi) requests disabled * (initial value) 1 transmit data empty interrupt (txi) requests enabled note: * txi interrupt request cancellation can be performed by reading 1 from the tdre flag, then clearing it to 0, or clearing the tie bit to 0. rev.6.00 oct.28.2004 page 473 of 1016 rej09b0138-0600h bit 6?receive interrupt enable (rie): enables or disables receive data full interrupt (rxi) request and receive error interrupt

error interrupt (eri) request disabled * (initial value) 1 receive data full interrupt (rxi) request and receive error interrupt (eri) request enabled note: * rxi and eri interrupt request cancellation can be performed by reading 1 from the rdrf flag, or the fer, per, or orer flag, then clearing the flag to 0, or clearing the rie bit to 0. bit 5?ransmit enable (te): enables or disables the start of serial transmission by the sci. bit 5 te description 0 transmission disabled * 1 (initial value) 1 transmission enabled * 2 notes: 1. the tdre flag in ssr is fixed at 1. 2. in this state, serial transmission is started when transmit data is written to tdr and the tdre flag in ssr is cleared to 0. smr setting must be performed to decide the transfer format before setting the te bit to 1. bit 4?eceive enable (re): enables or disables the start of serial reception by the sci. bit 4 re description 0 reception disabled * 1 (initial value) 1 reception enabled * 2 notes: 1. clearing the re bit to 0 does not affect the rdrf, fer, per, and orer flags, which retain their states. 2. serial reception is started in this state when a start bit is detected in asynchronous mode or serial clock input is detected in clocked synchronous mode. smr setting must be performed to decide the transfer format before setting the re bit to 1. bit 3?ultiprocessor interrupt enable (mpie): enables or disables multiprocessor interrupts. the mpie bit setting is only valid in asynchronous mode when the mp bit in smr is set to 1. rev.6.00 oct.28.2004 page 474 of 1016 rej09b0138-0600h the mpie bit setting is invalid in clocked synchronous mode or when the mp bit is cleared to 0. bit 3 mpie description 0 multiprocessor interrupts disabled (normal reception performed) (initial value) [clearing conditions] when the mpie bit is cleared to 0 when mpb= 1 data is received 1 multiprocessor interrupts enabled * receive data full interrupt (rxi) requests, receive error interrupt (eri) requests, and setting of the rdrf, fer, and orer flags in ssr are disabled until data with the multiprocessor bit set to 1 is received. note: * when receive data including mpb = 0 is received, receive data transfer from rsr to rdr, receive error detection, and setting of the rdrf, fer, and orer flags in ssr, is not performed. when receive data including mpb = 1 is received, the mpb bit in ssr is set to 1, the mpie bit is cleared to 0 automatically, and generation of rxi and eri interrupts (when the tie and rie bits in scr are set to 1) and fer and orer flag setting is enabled. bit 2?transmit end interrupt enable (teie): enables or disables transmit end interrupt (tei) request generation when there is no valid transmit data in tdr in msb data transmission. bit 2 teie description 0 transmit end interrupt (tei) request disabled * (initial value) 1 transmit end interrupt (tei) request enabled * note: * tei cancellation can be performed by reading 1 from the tdre flag in ssr, then clearing it to 0 and clearing the tend flag to 0, or clearing the teie bit to 0. bits 1 and 0?lock enable 1 and 0 (cke1, cke0): these bits are used to select the sci clock source and enable or disable clock output from the sck pin. the combination of the cke1 and cke0 bits determines whether the sck pin functions as an i/o port, the serial clock output pin, or the serial clock input pin. the setting of the cke0 bit, however, is only valid for internal clock operation (cke1 = 0) in asynchronous mode. the cke0 bit setting is invalid in clocked synchronous mode, and in the case of external clock operation (cke1 = 1). note that the sci? operating mode must be decided using smr before setting the cke1 and cke0 bits. rev.6.00 oct.28.2004 page 475 of 1016 rej09b0138-0600h for details of clock source selection, see

modes: asynchronous mode in which synchronization is achieved character by character, and clocked synchronous mode in which synchronization is achieved with clock pulses. selection of asynchronous or clocked synchronous mode and the transmission format is made using smr as shown in table 14-8. the sci clock is determined by a combination of the c/ a bit in smr and the cke1 and cke0 bits in scr, as shown in table 14-9. asynchronous mode data length: choice of 7 or 8 bits choice of parity addition, multiprocessor bit addition, and addition of 1 or 2 stop bits (the combination of these parameters determines the transfer format and character length) detection of framing, parity, and overrun errors, and breaks, during reception choice of internal or external clock as sci clock source ? when internal clock is selected: the sci operates on the baud rate generator clock and a clock with the same frequency as the bit rate can be output ? when external clock is selected: a clock with a

asynchronous mode in asynchronous mode, characters are sent or received, each preceded by a start bit indicating the start of communication and one or two stop bits indicating the end of communication. serial communication is thus carried out with synchronization established on a character-by-character basis. inside the sci, the transmitter and receiver are independent units, enabling full-duplex communication. both the transmitter and the receiver also have a double-buffered structure, so that data can be read or written during transmission or reception, enabling continuous data transfer. figure 14-2 shows the general format for asynchronous serial communication. in asynchronous serial communication, the transmission line is usually held in the mark state (high level). the sci monitors the transmission line, and when it goes to the space state (low level), recognizes a start bit and starts serial communication. one serial communication character consists of a start bit (low level), followed by data (in lsb-first order), a parity bit (high or low level), and finally one or two stop bits (high level). in asynchronous mode, the sci performs synchronization at the falling edge of the start bit in reception. the sci samples the data on the 8th pulse of a clock with a frequency of 16 times the length of one bit, so that the transfer data is latched a t the center of each bit. lsb start bit msb idle state (mark state) stop bit 0 transmit/receive data d0 d1 d2 d3 d4 d5 d6 d7 0/1 1 1 1 1 serial data parity bit 1 bit 1 or 2 bits 7 or 8 bits 1 bit, or none one unit

setting of the c/ a bit in smr and the cke1 and cke0 bits in scr. for details of sci clock source selection, see table 14-9. when an external clock is input at the sck pin, the clock frequency should be 16 times the bit rate used. when the sci is operated on an internal clock, the clock can be output from the sck pin. the frequency of the clock output in this case is equal to the bit rate, and the phase is such that the rising edge of the clock is in the middle of the transmit data, as shown in figure 14-3. 0 1 frame d0 d1 d2 d3 d4 d5 d6 d7 0/1 1 1 figure 14-3 relation between output clock and transfer data phase (asynchronous mode) data transfer operations: sci initialization (asynchronous mode) before transmitting and receiving data, you should first clear the te and re bits in scr to 0, then initialize the sci as described below. when the operating mode, transfer format, etc., is changed, the te and re bits must be cleared to 0 before making the change using the following procedure. when the te bit is cleared to 0, the tdre flag is set to 1 and tsr is initialized. note that clearing the re bit to 0 does not change the contents of the rdrf, per, fer, and orer flags, or the contents of rdr. when an external clock is used the clock should not be stopped during operation, including initialization, since operation is uncertain. rev.6.00 oct.28.2004 page 492 of 1016

[1] the sci monitors the transmission line, and if a 0 stop bit is detected, performs internal synchronization and starts reception. [2] the received data is stored in rsr in lsb-to-msb order. [3] the parity bit and stop bit are received. after receiving these bits, the sci carries out the following checks. [a] parity check: the sci checks whether the number of 1 bits in the receive data agrees with the parity (even or odd) set in the o/ e bit in smr. [b] stop bit check: the sci checks whether the stop bit is 1. if there are two stop bits, only the first is checked. [c] status check: the sci checks whether the rdrf flag is 0, indicating that the receive data can be transferred from rsr to rdr. if all the above checks are passed, the rdrf flag is set to 1, and the receive data is stored in rdr. if a receive error* is detected in the error check, the operation is as shown in table 14-11. note: * subsequent receive operations cannot be performed when a receive error has occurred. also note that the rdrf flag is not set to 1 in reception, and so the error flags must be cleared to 0. [4] if the rie bit in scr is set to 1 when the rdrf flag changes to 1, a receive data full interrupt (rxi) request is generated. also, if the rie bit in scr is set to 1 when the orer, per, or fer flag changes to 1, a receive error interrupt (eri) request is generated. rev.6.00 oct.28.2004 page 498 of 1016 rej09b0138-0600h table 14-11 receive errors and conditions for occurrence receive error abbreviation occurrence condition data transfer overrun error orer when the next data reception is completed while the rdrf flag in ssr is set to 1 receive data is not transferred from rsr to rdr. framing error fer when the stop bit is 0 receive data is transferred from rsr to rdr. parity error per when the received data differs from the parity (even or odd) set in smr receive data is transferred from rsr to rdr. figure 14-8 shows an example of the operation for reception in asynchronous mode. rdrf fer 0 1 frame d0 d1 d7 0/1 1 0 d0 d1 d7 0/1 0 1 1 data start bit parity bit stop bit start bit data parity bit stop bit rxi interrupt request generated eri interrupt request generated by framing error idle state (mark state) rdr data read and rdrf flag cleared to 0 in rxi interrupt service routine figure 14-8 example of sci operation in reception (example with 8-bit data, parity, one stop bit) rev.6.00 oct.28.2004 page 499 of 1016 rej09b0138-0600h 14.3.3 multiprocessor communication function the multiprocessor communication function performs serial communication using the multiprocessor format, in which a multiprocessor bit is added to the transfer data, in asynchronous mode. use of this function enables data transfer to be performed among a number of processors sharing transmission lines. when multiprocessor communication is carried out, each receiving station is addressed by a unique id code. the serial communication cycle consists of two component cycles: an id transmission cycle which specifies the receiving station , and a data transmission cycle. the multiprocessor bit is used to differentiate between the id transmission cycle and the data transmission cycle. the transmitting station first sends the id of the receiving station with which it wants to perform serial communication as data with a 1 multiprocessor bit added. it then sends transmit data as data with a 0 multiprocessor bit added. the receiving station skips the data until data with a 1 multiprocessor bit is sent. when data with a 1 multiprocessor bit is received, the receiving station compares that data with its own id. the station whose id matches then receives the data sent next. stations whose id does not match continue to skip the data until data with a 1 multiprocessor bit is again received. in this way, data communication is carried out among a number of processors. figure 14-9 shows an example of inter-processor communication using the multiprocessor format. data transfer format: there are four data transfer formats. when the multiprocessor format is specified, the parity bit specification is invalid. for details, see table 14-10. clock: see the section on asynchronous mode. transmitting station receiving station a (id= 01) receiving station b (id= 02) receiving station c (id= 03) receiving station d (id= 04) serial transmission line serial data id transmission cycle= receiving station specification data transmission cycle= data transmission to receiving station specified by id (mpb= 1) (mpb= 0) h'01 h'aa legend: mpb: multiprocessor bit figure 14-9 example of inter-processor communication using multiprocessor format (transmission of data h'aa to receiving station a) rev.6.00 oct.28.2004 page 500 of 1016 rej09b0138-0600h data transfer operations: multiprocessor serial data transmission figure 14-10 shows a sample flowchart for multiprocessor serial data transmission. the following procedure should be used for multiprocessor serial data transmission. no rev.6.00 oct.28.2004 page 501 of 1016 rej09b0138-0600h in serial transmission, the sci operates as described below. [1] the sci monitors the tdre flag in ssr, and if is 0, recognizes that data has been written to tdr, and transfers the data from tdr to tsr. [2] after transferring data from tdr to tsr, the sci sets the tdre flag to 1 and starts transmission. if the tie bit is set to 1 at this time, a transmit data empty interrupt (txi) is generated. the serial transmit data is sent from the txd pin in the following order. [a] start bit: one 0-bit is output. [b] transmit data: 8-bit or 7-bit data is output in lsb-first order. [c] multiprocessor bit one multiprocessor bit (mpbt value) is output. [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 sci checks the tdre flag at the timing for sending the stop bit. if the tdre flag is cleared to 0, data is transferred from tdr to tsr, the stop bit is sent, and then serial transmission of the next frame is started. if the tdre flag is set to 1, the tend flag in ssr is set to 1, the stop bit is sent, and then the mark state is entered in which 1 is output continuously. if the teie bit in scr is set to 1 at this time, a transmission end interrupt (tei) request is generated. figure 14-11 shows an example of sci operation for transmission using the multiprocessor format. tdre tend 0 1

rej09b0138-0600h 14.3.4 operation in clocked synchronous mode in clocked synchronous mode, data is transmitted or received in synchronization with clock pulses, making it suitable for high-speed serial communication. inside the sci, the transmitter and receiver are independent units, enabling full-duplex communication by use of a common clock. both the transmitter and the receiver also have a double-buffered structure, so that data can be read or written during transmission or reception, enabling continuous data transfer. figure 14-14 shows the general format for clocked synchronous serial communication. don?t care don?t care one unit of transfer data (character or frame) bit 0 serial data serial clock bit 1 bit 3 bit 4 bit 5 lsb msb bit 2 bit 6 bit 7 * note: * high except in continuous transfer * figure 14-14 data format in synchronous communication in clocked synchronous serial communication, data on the transmission line is output from one falling edge of the serial clock to the next. data confirmation is guaranteed at the rising edge of the serial clock. in clocked serial communication, one character consists of data output starting with the lsb and ending with the msb. after the msb is output, the transmission line holds the msb state. in clocked synchronous mode, the sci receives data in synchronization with the rising edge of the serial clock. data transfer format: a fixed 8-bit data format is used. no parity or multiprocessor bits are added. clock: either an internal clock generated by the on-chip baud rate generator or an external serial clock input at the sck pin can be selected, according to the setting of the c/ a bit in smr and the cke1 and cke0 bits in scr. for details of sci clock source selection, see table 14-9. when the sci is operated on an internal clock, the serial clock is output from the sck pin. eight serial clock pulses are output in the transfer of one character, and when no transfer is performed the clock is fixed high. when only receive operations are performed, however, the serial clock is output until an overrun error occurs or the re bit is cleared to 0. if you want to perform receive operations in units of one character, you should select an external clock as the clock source. rev.6.00 oct.28.2004 page 506 of 1016 rej09b0138-0600h data transfer operations: sci initialization (clocked synchronous mode) before transmitting and receiving data, you should first clear the te and re bits in scr to 0, then initialize the sci as described below. when the operating mode, transfer format, etc., is changed, the te and re bits must be cleared to 0 before making the change using the following procedure. when the te bit is cleared to 0, the tdre flag is set to 1 and tsr is initialized. note that clearing the re bit to 0 does not change the contents of the rdrf, per, fer, and orer flags, or the contents of rdr. figure 14-15 shows a sample sci initialization flowchart. wait rev.6.00 oct.28.2004 page 507

transmission. no rev.6.00 oct.28.2004 page 508 of 1016 rej09b0138-0600h in serial transmission, the sci operates as described below. [1] the sci monitors the tdre flag in ssr, and if is 0, recognizes that data has been written to tdr, and transfers the data from tdr to tsr. [2] after transferring data from tdr to tsr, the sci sets the tdre flag to 1 and starts transmission. if the tie bit is set to 1 at this time, a transmit data empty interrupt (txi) is generated. when clock output mode has been set, the sci outputs 8 serial clock pulses. when use of an external clock has been specified, data is output synchronized with the input clock. the serial transmit data is sent from the txd pin starting with the lsb (bit 0) and ending with the msb (bit 7). [3] the sci checks the tdre flag at the timing for sending the msb (bit 7). if the tdre flag is cleared to 0, data is transferred from tdr to tsr, and serial transmission of the next frame is started. if the tdre flag is set to 1, the tend flag in ssr is set to 1, the msb (bit 7) is sent, and the txd pin maintains its state. if the teie bit in scr is set to 1 at this time, a tei interrupt request is generated. [4] after completion of serial transmission, the sck pin is fixed. figure 14-17 shows an example of sci operation in transmission. transfer direction bit 7 serial data serial clock 1 frame tdre tend bit 0 bit 7 bit 0 bit 1 bit 7 bit 6 data written to tdr and tdre flag cleared to 0 in txi interrupt service routine tei interrupt request generated txi interrupt request generated txi interrupt request generated figure 14-17 example of sci operation in transmission rev.6.00 oct.28.2004 page 509 of 1016 rej09b0138-0600h serial data reception (clocked synchronous mode) figure 14-18 shows a sample flowchart for serial reception. the following procedure should be used for serial data reception. when changing the operating mode from asynchronous to clocked synchronous, be sure to check that the orer, per, and fer flags are all cleared to 0. the rdrf flag will not be set if the fer or per flag is set to 1, and neither transmit nor receive operations will be possible. yes rev.6.00 oct.28.2004 page 510 of 1016 rej09b0138-0600h in serial reception, the sci operates as described below. [1] the sci performs internal initialization in synchronization with serial clock input or output. [2] the received data is stored in rsr in lsb-to-msb order. after reception, the sci checks whether the rdrf flag is 0 and the receive data can be transferred from rsr to rdr. if this check is passed, the rdrf flag is set to 1, and the receive data is stored in rdr. if a receive error is detected in the error check, the operation is as shown in table 14-11. neither transmit nor receive operations can be performed subsequently when a receive error has been found in the error check. [3] if the rie bit in scr is set to 1 when the rdrf flag changes to 1, a receive data full interrupt (rxi) request is generated. also, if the rie bit in scr is set to 1 when the orer flag changes to 1, a receive error interrupt (eri) request is generated. figure 14-19 shows an example of sci operation in reception. bit 7 serial data serial clock 1 frame rdrf orer bit 0 bit 7 bit 0 bit 1 bit 6 bit

page 512 of 1016 rej09b0138-0600h 14.4 sci interrupts the sci has four interrupt sources: the transmit-end interrupt (tei) request, receive-error interrupt (eri) request, receive- data-full interrupt (rxi) request, and transmit-data-empty interrupt (txi) request. table 14-12 shows the interrupt sources and their relative priorities. individual interrupt sources can be enabled or disabled with the tie, rie, and teie bits in the scr. each kind of interrupt request is sent to the interrupt controller independently. when the tdre flag in ssr is set to 1, a txi interrupt request is generated. when the tend flag in ssr is set to 1, a tei interrupt request is generated. a txi interrupt can activate the dmac or dtc to perform data transfer. the tdre flag is cleared to 0 automatically when data transfer is performed by the dmac or dtc. the dmac and dtc cannot be activated by a tei interrupt request. when the rdrf flag in ssr is set to 1, an rxi interrupt request is generated. when the orer, per, or fer flag in ssr is set to 1, an eri interrupt request is generated. an rxi interrupt can activate the dmac or dtc to perform data transfer. the rdrf flag is cleared to 0 automatically when data transfer is performed by the dmac or dtc. the dmac and dtc cannot be activated by an eri interrupt request. also note that the dmac cannot be activated by an sci channel 2 interrupt. rev.6.00

possible tei interrupt due to transmission end (tend) not possible not possible low note: * this table shows the initial state immediately after a reset. relative priorities among channels can be changed by means of icr and ipr. a tei interrupt is requested when the tend flag is set to 1 while the teie bit is set to 1. the tend flag is cleared at the same time as the tdre flag. consequently, if a tei interrupt and a txi interrupt are requested simultaneously, the txi interrupt may be accepted first, with the result that the tdre and tend flags are cleared. note that the tei interrupt will not be accepted in this case. rev.6.00 oct.28.2004 page 514 of 1016 rej09b0138-0600h 14.5 usage notes the following points should be noted when using the sci. relation between writes to tdr and the tdre flag the tdre flag in ssr is a status flag that indicates that transmit data has been transferred from tdr to tsr. when the sci transfers data from tdr to tsr, the tdre flag is set to 1. data can be written to tdr regardless of the state of the tdre flag. however, if new data is written to tdr when the tdre flag is cleared to 0, the data stored in tdr will be lost since it has not yet been transferred to tsr. it is therefore essential to check that the tdre flag is set to 1 before writing transmit data to tdr. operation when multiple receive errors occur simultaneously if a number of receive errors occur at the same time, the state of the status flags in ssr is as shown in table 14-13. if there is an overrun error, data is not transferred from rsr to rdr, and the receive data is lost. table 14-13 state of ssr status flags and transfer of receive data ssr status flags receive data transfer rdrf orer fer per rsr to rdr receive error status 1100 overrun error 0010 framing error 0001 parity error 1110 overrun error + framing error 1101 overrun error + parity error 0011 framing error + parity error 1111 overrun error + framing error + parity error notes: : receive data is transferred from rsr to rdr. : receive data is not transferred from rsr to rdr. rev.6.00 oct.28.2004 page 515 of 1016 rej09b0138-0600h break detection and processing (asynchronous mode only): when framing error (fer) detection is performed, a break can be detected by reading the rxd pin value directly. in a break, the input from the rxd pin becomes all 0s, and so the fer flag is set, and the parity error flag (per) may also be set. note that, since the sci continues the receive operation after receiving a break, even if the fer flag is cleared to 0, it will be set to 1 again. sending a break (asynchronous mode only): the txd pin has a dual function as an i/o port whose direction (input or output) is determined by dr and ddr. this can be used to send a break. between serial transmission initialization and setting of the te bit to 1, the mark state is replaced by the value of dr (the pin does not function as the txd pin until the te bit is set to 1). consequently, ddr and dr for the port corresponding to the txd pin are first set to 1. to send a break during serial transmission, first clear dr to 0, then clear the te bit to 0. when the te bit is cleared to 0, the transmitter is initialized regardless of the current transmission state, the txd pin becomes an i/o port, and 0 is output from the txd pin. receive error flags and transmit operations (clocked synchronous mode only): transmission cannot be started when a receive error flag (orer, per, or fer) is set to 1, even if the tdre flag is cleared to 0. be sure to clear the receive error flags to 0 before starting transmission. note also that receive error flags cannot be cleared to 0 even if the re bit is cleared to 0. receive data sampling timing and reception margin in asynchronous mode: in asynchronous mode, the sci operates on a basic clock with a frequency of 16 times the transfer rate. in reception, the sci samples the falling edge of the start bit using the basic clock, and performs internal synchronization. receive data is latched internally at the rising edge of the 8th pulse of the basic clock. this is illustrated in figure 14-21. internal basic clock 16 clocks 8 clocks

and a margin of 20% to 30% should be allowed in system design. restrictions on use of dmac or dtc when an external clock source is used as the serial clock, the transmit clock should not be input until at least 5 ? clock cycles after tdr is updated by the dmac or dtc. misoperation may occur if the transmit clock is input within 4 ? clocks after tdr is updated.

operate in the same way as for the normal sci. for details, see section 14.2.7, serial status register (ssr). bit 4?error signal status (ers): in smart card interface mode, bit 4 indicates the status

the setting conditions for the tend bit, are as shown below. bit 2 tend description 0 [clearing conditions] (initial value) when 0 is written to tdre after reading tdre = 1 when the dmac or dtc is

cleared to 0 when the normal smart card interface is used. in gsm mode, this bit is set to 1, the timing of setting of the tend flag that indicates transmission completion is advanced and clock output

follows. one frame consists of 8-bit data plus a parity bit. in transmission, a guard time of at least 2 etu (elementary time unit: the time for transfer of 1 bit) is left between the end of the parity bit and the start of the next frame. if a parity error is detected during reception, a low error signal level is output for one etu period, 10.5 etu after the star t bit. if the error signal is sampled during transmission, the same data is transmitted automatically after the elapse of 2 etu or longer. only asynchronous communication is supported; there is no clocked synchronous communication function. 15.3.2 pin connections figure 15-2 shows a schematic diagram of smart card interface related pin connections. in communication with an ic card, since both transmission and reception are carried out on a single data transmission line, the txd pin and rxd pin should be connected with the lsi pin. the data transmission line should be pulled up to the v cc power supply with a resistor. when the clock generated on the smart card interface is used by an ic card, the sck pin output is input to the clk pin of the ic card. no connection is needed if the ic card uses an internal clock. lsi port output is used as the reset signal. other pins must normally be connected to the power supply or ground. txd rxd sck rx (port) h8s/2357 group i/o clk rst v cc connected equipment ic card data

transmission/reception is possible, enabling self-diagnosis to be carried out. rev.6.00 oct.28.2004 page 525 of 1016 rej09b0138-0600h 15.3.3 data format figure 15-3 shows the smart card interface data format. in reception in this mode, a parity check is carried out on each frame, and if an error is detected an error signal is sent back to the transmitting end, and retransmission of the data is requested. if an error signal is sampled during transmission, the same data is retransmitted. ds d0 d1 d2 d3 d4 d5 d6 d7 dp when there is no parity error transmitting station output ds d0 d1 d2 d3 d4 d5 d6 d7 dp when a parity error occurs transmitting station output de receiving station output start bit data bits parity bit error signal legend: ds: d0 to d7: dp: de: figure 15-3 smart card interface data format the operation sequence is as follows. [1] when the data line is not in use it is in the high-impedance state, and is fixed high with a pull-up resistor. [2] the transmitting station starts transfer of one frame of data. the data frame starts with a start bit (ds, low-level), followed by 8 data bits (d0 to d7) and a parity bit (dp). [3] with the smart card interface, the data line then returns to the high-impedance state. the data line is pulled high with a pull-up resistor. [4] the receiving station carries out a parity check. if there is no parity error and the data is received normally, the receiving station waits for reception of the next data. if a parity error occurs, however, the receiving station outputs an error signal (de, low-level) to request retransmission of the data. after outputting the error signal for the prescribed length of time, the receiving station places the signal line in the high-impedance state again. the signal line is pulled high again by a pull-up resistor. [5] if the transmitting station does not receive an error signal, it proceeds to transmit the next data frame. if it does receive an error signal, however, it returns to step [2] and retransmits the erroneous data. rev.6.00 oct.28.2004 page 526 of 1016 rej09b0138-0600h 15.3.4 register settings table 15-3 shows a bit map of the registers used by the smart card interface. bits indicated as 0 or 1 must be set to the value shown. the setting of other bits is described below. table 15-3 smart card interface register settings bit register bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 smr gm 0 1 o/ e 1 0 cks1 cks0 brr brr7 brr6 brr5 brr4 brr3 brr2 brr1 brr0 scr tie rie te re 0 0 cke1 * cke0 tdr tdr7 tdr6 tdr5 tdr4 tdr3 tdr2 tdr1 tdr0 ssr tdre rdrf orer ers per tend 0 0 rdr rdr7 rdr6 rdr5 rdr4 rdr3 rdr2 rdr1 rdr0 scmr ???? sdir sinv ? smif notes: ? : not used. * the cke1 bit must be cleared to 0 when the gm bit in smr is cleared to 0. smr setting: the gm bit is cleared to 0 in normal smart card interface mode, and set to 1 in gsm mode. the o/ e bit is cleared to 0 if the ic card is of the direct convention type, and set to 1 if of the inverse convention type. bits cks1 and cks0 select the clock source of the on-chip baud rate generator. see section 15.3.5, clock. brr setting: brr is used to set the bit rate. see section 15.3.5, clock, for the method of calculating the value to be set. scr setting: the function of the tie, rie, te, and re bits is the same as for the normal sci. for details, see section 14, serial communication interface (sci). bits cke1 and cke0 specify the clock output. when the gm bit in smr is cleared to 0, set these bits to b'00 if a clock is not to be output, or to b'01 if a clock is to be output. when the gm bit in smr is set to 1, clock output is performed. the clock output can also be fixed high or low. smart card mode register (scmr) setting: the sdir bit is cleared to 0 if the ic card is of the direct convention type, and set to 1 if of the inverse convention type. the sinv bit is cleared to 0 if the ic card is of the direct convention type, and set to 1 if of the inverse convention type. the smif bit is set to 1 in the case of the smart card interface. examples of register settings and the waveform of the start character are shown below for the two types of ic card (direct convention and inverse convention). rev.6.00 oct.28.2004 page 527 of 1016 rej09b0138-0600h direct convention (sdir = sinv = o/ e = 0) ds d0 d1 d2 d3 d4 d5 d6 d7 dp azzazzzaaz (z) (z) state with the direct convention type, the logic 1 level corresponds to state z and the logic 0 level to state a, and transfer is performed in lsb-first order. the start character data above is h'3b. the parity bit is 1 since even parity is stipulated for the smart card. ? inverse convention (sdir = sinv = o/ e = 1) ds d7 d6 d5 d4 d3 d2 d1 d0 dp azzaaaaaaz (z) (z) state with the inverse convention type, the logic 1 level corresponds to state a and the logic 0 level to state z, and transfer is performed in msb-first order. the start character data above is h'3f. the parity bit is 0, corresponding to state z, since even parity is stipulated for the smart card. with the h8s/2357 group, inversion specified by the sinv bit applies only to the data bits, d7 to d0. for parity bit inversion, the o/ e bit in smr is set to odd parity mode (the same applies to both transmission and reception). 15.3.5 clock only an internal clock generated by the on-chip baud rate generator can be used as the transmit/receive clock for the smart card interface. the bit rate is set with brr and the cks1 and cks0 bits in smr. the formula for calculating the bit rate is as shown below. table 15-5 shows some sample bit rates. if clock output is selected by setting cke0 to 1, a clock with a frequency of 372 times the bit rate is output from the sck pin. b = ? 1488 2 2ne1 (n + 1) 10 6 where: n = value set in brr (0 n 255) b = bit rate (bit/s) ? = operating frequency (mhz) n = see table 15-4 table 15-4 correspondence between n and cks1, cks0 n cks1 cks0 000 11 210 31 rev.6.00 oct.28.2004 page 528 of 1016 rej09b0138-0600h table 15-5 examples of bit rate b (bit/s) for various brr settings (when n = 0) ?

[1] clear the te and re bits in scr to 0. [2] clear the error flags ers, per, and orer in ssr to 0. [3] set the o/ e bit and cks1 and cks0 bits in smr. clear the c/ a , chr, and mp bits to 0, and set the stop and pe bits to 1. [4] set the smif, sdir, and sinv bits in scmr. when the smif bit is set to 1, the txd and rxd pins are both switched from ports to sci pins, and are placed in the high-impedance state. [5] set the value corresponding to the bit rate in brr. [6] set the cke0 bit in scr. clear the tie, rie, te, re, mpie, teie and cke1 bits to 0. if the cke0 bit is set to 1, the clock is output from the sck pin. [7] wait at least one bit interval, then set the tie, rie, te, and re bits in scr. do not set the te bit and re bit at the same time, except for self-diagnosis. serial data transmission: as data transmission in smart card mode involves error signal sampling and retransmission processing, the processing procedure is different from that for the normal sci. figure 15-4 shows a flowchart for transmitting, and figure 15-5 shows the relation between a transmit operation and the internal registers. [1] perform smart card interface mode initialization as described above in initialization. [2] check that the ers error flag in ssr is cleared to 0. [3] repeat steps [2] and [3] until it can be confirmed that the tend flag in ssr is set to 1. [4] write the transmit data to tdr, clear the tdre flag to 0, and perform the transmit operation. the tend flag is cleared to 0. [5] when transmitting data continuously, go back to step [2]. [6] to end transmission, clear the te bit to 0. with the above processing, interrupt servicing or data transfer by the dmac or dtc is possible. if transmission ends and the tend flag is set to 1 while the tie bit is set to 1 and interrupt requests are enabled, a transmit data empty interrupt (txi) request will be generated. if an error occurs in transmission and the ers flag is set to 1 while the rie bit is set to 1 and interrupt requests are enabled, a transfer error interrupt (eri) request will be generated. the timing for setting the tend flag depends on the value of the gm bit in smr. the tend flag set timing is shown in figure 15-6. if the dmac or dtc is activated by a txi request, the number of bytes set in the dmac or dtc can be transmitted automatically, including automatic retransmission. for details, see interrupt operations and data transfer operation by dmac or dtc below. rev.6.00 oct.28.2004 page 530 of 1016 rej09b0138-0600h initialization no yes clear te bit to 0 start transmission start no no no yes yes yes yes no end write data to tdr, and clear tdre flag in ssr to 0 error processing error processing tend=1? all data transmitted? tend=1? ers=0? ers=0? figure 15-4 example of transmission processing flow rev.6.00 oct.28.2004 page 531 of 1016 rej09b0138-0600h (1) data write tdr tsr (shift register) data 1 (2) transfer from tdr to tsr data 1 data 1 ; data remains in tdr (3) serial data output note: when the ers flag is set, it should be cleared until transfer of the last bit (d7 in lsb-first transmission, d0 in msb-first transmission) of the next transfer data to be transmitted has been completed. in case of normal transmission: tend flag is set in case of transmit error: ers flag is set steps (2) and (3) above are repeated until the tend flag is set i/o signal line output data 1 data 1 figure 15-5 relation between transmit operation and internal registers ds d0 d1 d2 d3 d4 d5 d6 d7 dp i/o data 12.5 etu txi (tend interrupt) 11.0 etu de guard time when gm = 1 note: etu: elementary time unit (time for transfer of 1 bit) legend: ds: start bit d0 to d7: data bits dp: parity bit de: error signal when gm = 0 figure 15-6 tend flag generation timing in transmission operation rev.6.00 oct.28.2004 page 532 of 1016 rej09b0138-0600h serial data reception: data reception in smart card mode uses the same processing procedure as for the normal sci. figure 15-7 shows an example of the transmission processing flow. [1] perform smart card interface mode initialization as described above in initialization. [2] check that the orer flag and per flag in ssr are cleared to 0. if either is set, perform the appropriate receive error processing, then clear both the orer and the per flag to 0. [3] repeat steps [2] and [3] until it can be confirmed that the rdrf flag is set to 1. [4] read the receive data from rdr. [5] when receiving data continuously, clear the rdrf flag to 0 and go back to step [2]. [6] to end reception, clear the re bit to 0. initialization read rdr and clear rdrf flag in ssr to 0 clear re bit to 0 start reception start error processing no no no yes yes orer = 0 and per = 0 rdrf=1? all data received? yes figure 15-7 example of reception processing flow with the above processing, interrupt servicing or data transfer by the dmac or dtc is possible. if reception ends and the rdrf flag is set to 1 while the rie bit is set to 1 and interrupt requests are enabled, a receive data full interrupt (rxi) request will be generated. if an error occurs in reception and either the orer flag or the per flag is set to 1, a transfer error interrupt (eri) request will be generated. if the dmac or dtc is activated by an rxi request, the receive data in which the error occurred is skipped, and only the number of bytes of receive data set in the dmac or dtc are transferred. for details, see interrupt operation and data transfer operation by dmac or dtc below. rev.6.00 oct.28.2004 page 533 of 1016 rej09b0138-0600h if a parity error occurs during reception and the per is set to 1, the received data is still transferred to rdr, and therefore this data can be read. mode switching operation: when switching from receive mode to transmit mode, first confirm that the receive operation has been completed, then start from initialization, clearing re bit to 0 and setting te bit to 1. the rdrf flag or the per and orer flags can be used to check that the receive operation has been completed. when switching from transmit mode to receive mode, first confirm that the transmit operation has been completed, then start from initialization, clearing te bit to 0 and setting re bit to 1. the tend flag can be used to check that the transmit operation has been completed. fixing clock output level: when the gsm bit in smr is set to 1, the clock output level can be fixed with bits cke1 and cke0 in scr. at this time, the minimum clock pulse width can be made the specified width. figure 15-8 shows the timing for fixing the clock output level. in this example, gsm is set to 1, cke1 is cleared to 0, and the cke0 bit is controlled. sck specified pulse width scr write (cke0 = 0) scr write (cke0 = 1) specified pulse width figure 15-8 timing for fixing clock output level interrupt operation: there are three interrupt sources in smart card interface mode: transmit data empty interrupt (txi) requests, transfer error interrupt (eri) requests, and receive data full interrupt (rxi) requests. the transmit end interrupt (tei) request is not used in this mode. when the tend flag in ssr is set to 1, a txi interrupt request is generated. when the rdrf flag in ssr is set to 1, an rxi interrupt request is generated. when any of flags orer, per, and ers in ssr is set to 1, an eri interrupt request is generated. the relationship between the operating states and interrupt sources is shown in table 15-8. table 15-8 smart card mode operating states and interrupt sources operating state flag enable bit interrupt source dmac activation dtc activation transmit mode normal operation tend tie txi possible possible error ers rie eri not possible not possible receive mode normal operation rdrf rie rxi possible possible error per, orer rie eri not possible not possible data transfer operation by dmac or dtc: in smart card mode, as with the normal sci, transfer can be carried out using the dmac or dtc. in a transmit operation, the tdre flag is also set to 1 at the same time as the tend flag in ssr, and a txi interrupt is generated. if the txi request is designated beforehand as a dmac or dtc activation source, the dmac or dtc will be activated by the txi request, and transfer of the transmit data will be carried out. the tdre rev.6.00 oct.28.2004 page 534 of 1016 rej09b0138-0600h and tend flags are automatically cleared to 0 when data transfer is performed by the dmac or dtc. in the event of an error, the sci retransmits the same data automatically. the tend flag remains cleared to 0 during this time, and the dmac is not activated. thus, the number of bytes specified by the sci and dmac are transmitted automatically even in retransmission following an error. however, the ers flag is not cleared automatically when an error occurs, and so the rie bit should be set to 1 beforehand so that an eri request will be generated in the event of an error, and the ers flag will be cleared. when performing transfer using the dmac or dtc, it is essential to set and enable the dmac or dtc before carrying out sci setting. for details of the dmac and dtc setting procedures, see section 7, dma controller, and section 8, data transfer controller. in a receive operation, an rxi interrupt request is generated when the rdrf flag in ssr is set to 1. if the rxi request is designated beforehand as a dmac or dtc activation source, the dmac or dtc will be activated by the rxi request, and transfer of the receive data will be carried out. the rdrf flag is cleared to 0 automatically when data transfer is performed by the dmac or dtc. if an error occurs, an error flag is set but the rdrf flag is not. consequently, the dmac or dtc is not activated, but instead, an eri interrupt request is sent to the cpu. therefore, the error flag should be cleared. 15.3.7 operation in gsm mode switching the mode: when switching between smart card interface mode and software standby mode, the following switching procedure should be followed in order to maintain the clock duty. when changing from smart card interface mode to software standby mode [1] set the data register (dr) and data direction register (ddr) corresponding to the sck pin to the value for the fixed output state in software standby mode. [2] write 0 to the te bit and re bit in the serial control register (scr) to halt transmit/receive operation. at the same time, set the cke1 bit to the value for the fixed output state in software standby mode. [3] write 0 to the cke0 bit in scr to halt the clock. [4] wait for one serial clock period. during this interval, clock output is fixed at the specified level, with the duty preserved.

[1] single mode is selected (scan = 0), input channel an1 is selected (ch2 = 0, ch1 = 0, ch0? 1), the a/d interrupt is enabled (adie = 1), and a/d conversion is started (adst = 1). [2] when a/d conversion is completed, the result is transferred to addrb. at the same time the adf flag is set to 1, the adst bit is cleared to 0, and the a/d converter becomes idle. [3] since adf = 1 and adie = 1, an adi interrupt is requested. [4] the a/d interrupt handling routine starts. [5] the routine reads adcsr, then writes 0 to the adf flag. [6] the routine reads and processes the connection result (addrb). [7] execution of the a/d interrupt handling routine ends. after that, if the adst bit is set to 1, a/d conversion starts again and steps [2] to [7] are repeated. adie adst adf state of channel 0 (an0) a/d conversion starts 2 1 addra addrb addrc addrd state of channel 1 (an1) state of channel 2 (an2) state of channel 3 (an3) note: * vertical arrows ( ) indicate instructions executed by software. set * set * clear * clear * a/d conversion result 1 a/d conversion a/d conversion result 2 read conversion result read conversion result idle idle idle idle idle idle a/d conversion set * figure 16-3 example of a/d converter operation (single mode, channel 1 selected) rev.6.00 oct.28.2004 page 548 of 1016 rej09b0138-0600h 16.4.2 scan mode (scan = 1) scan mode is useful for monitoring analog inputs in a group of one or more channels. when the adst bit is set to 1 by a software, timer or external trigger input, a/d conversion starts on the first channel in the group (an0). when two or more channels are selected, after conversion of the first channel ends, conversion of the second channel (an1) starts immediately. a/d conversion continues cyclically on the selected channels until the adst bit is cleared to 0. the conversion results are transferred for storage into the addr registers corresponding to the channels. when the operating mode or analog input channel must be changed during analog conversion, to prevent incorrect operation, first clear the adst bit to 0 in adcsr to halt a/d conversion. after making the necessary changes, set the adst bit to 1 to start a/d conversion again. the adst bit can be set at the same time as the operating mode or input channel is changed. typical operations when three channels (an0 to an2) are selected in scan mode are described next. figure 16-4 shows a timing diagram for this example. [1] scan mode is selected (scan = 1), scan group 0 is selected (ch2 = 0), analog input channels an0 to an2 are selected (ch1 = 1, ch0 = 0), and a/d conversion is started (adst = 1) [2] when a/d conversion of the first channel (an0) is completed, the result is transferred to addra. next, conversion of the second channel (an1) starts automatically. [3] conversion proceeds in the same way through the third channel (an2). [4] when conversion of all the selected channels (an0 to an2) is completed, the adf flag is set to 1 and conversion of the first channel (an0) starts again. if the adie bit is set to 1 at this time, an adi interrupt is requested after a/d conversion ends. [5] steps [2] to [4] are repeated as long as the adst bit remains set to 1. when the adst bit is cleared to 0, a/d conversion stops. after that, if the adst bit is set to 1, a/d conversion starts again from the first channel (an0). adst adf addra addrb addrc addrd state of channel 0 (an0) state of channel 1 (an1) state of channel 2 (an2) state of channel 3 (an3) set * 1 clear * 1 idle notes: 1. vertical arrows ( ) indicate instructions executed by software. 2. data currently being converted is ignored. clear * 1 idle idle a/d conversion time idle continuous a/d conversion execution a/d conversion 1 idle idle idle idle idle transfer * 2 a/d conversion 3 a/d conversion 2 a/d conversion 5 a/d conversion 4 a/d conversion result 1 a/d conversion result 2 a/d conversion result 3 a/d conversion result 4 figure 16-4 example of a/d converter operation (scan mode, channels an0 to an2 selected) rev.6.00 oct.28.2004 page 549 of 1016 rej09b0138-0600h 16.4.3 input sampling and a/d conversion time the a/d converter has a on-chip sample-and-hold circuit. the a/d converter samples the analog input at a time t d after the adst bit is set to 1, then starts conversion. figure 16-5 shows the a/d conversion timing. table 16-4 indicates the a/d conversion time. as indicated in figure 16-5, the a/d conversion time includes t d and the input sampling time. the length of t d varies depending on the timing of the write access to adcsr. the total conversion time therefore varies within the ranges indicated in table 16-4. in scan mode, the values given in table 16-4 apply to the first conversion time. in the second and subsequent conversions the conversion time is fixed at 256 states when cks = 0 or 128 states when cks = 1.

(2) relation between av cc , av ss and v cc , v ss as the relationship between av cc , av ss and v cc , v ss , set av ss = v ss . if the a/d converter is not used, the av cc and av ss pins must on no account be left open. (3) v ref input range the analog reference voltage input at the v ref pin set in the range v ref av cc . note:if conditions (1), (2), and (3) above are not met, the reliability of the device may be adversely affected. notes on board design: in board design, digital circuitry and analog circuitry should be as mutually isolated as possible, and layout in which digital circuit signal lines and analog circuit signal lines cross or are in close proximity should be avoided as far as possible. failure to do so may result in incorrect operation of the analog circuitry due to inductance, adversely affecting a/d conversion values. also, digital circuitry must be isolated from the analog input signals (an0 to an7), analog reference power supply (v ref ), and analog power supply (av cc ) by the analog ground (av ss ). also, the analog ground (av ss ) should be connected at one point to a stable digital ground (v ss ) on the board. notes on noise countermeasures: a protection circuit connected to prevent damage due to an abnormal voltage such as an excessive surge at the analog input pins (an0 to an7) and analog reference power supply (v ref ) should be connected between av cc and av ss as shown in figure 16-7. also, the bypass capacitors connected to av cc and v ref and the filter capacitor connected to an0 to an7 must be connected to av ss . if a filter capacitor is connected as shown in figure 16-7, the input currents at the analog input pins (an0 to an7) are averaged, and so an error may arise. also, when a/d conversion is performed frequently, as in scan mode, if the current charged and discharged by the capacitance of the sample-and-hold circuit in the a/d converter exceeds the current input via the input impedance (r in ), an error will arise in the analog input pin voltage. careful consideration is therefore required when deciding the circuit constants. rev.6.00 oct.28.2004 page 552 of 1016 rej09b0138-0600h av cc * 1 * 1 v ref an0 to an7 av ss notes: values are reference values. 1. 2. r in : input impedance r in * 2 100 0.1 f 0.01 f 10 f figure 16-7 example of analog input protection circuit a/d conversion precision definitions: h8s/2357 group a/d conversion precision definitions are given below. ?

(v pp ) in prom mode is 12.5 v. if the prom programmer is set to renesas technology hn27c101 specifications, v pp will be 12.5 v. applied voltages in excess of the specified values can permanently destroy the mcu. be particularly careful about the prom programmer? overshoot characteristics. before programming, check that the mcu is correctly mounted in the prom programmer. overcurrent damage to the mcu can result if the index marks on the prom programmer, socket adapter, and mcu are not correctly aligned. do not touch the socket adapter or mcu while programming. touching either of these can cause contact faults and programming errors. the mcu cannot be programmed in page programming mode. select the programming mode carefully. the size of the h8s/2357 prom is 128 kbytes. always set addresses within the range h'00000 to h'1ffff. during programming, write h'ff to unused addresses to avoid verification errors. rev.6.00 oct.28.2004 page 573 of 1016 rej09b0138-0600h 19.5.4 reliability of programmed data an effective way to assure the data retention characteristics of the programmed chips is to bake them at 150 c, then screen them for data errors. this procedure quickly eliminates chips with prom memory cells prone to early failure. figure 19-6 shows the recommended screening procedure. mount program chip and verify data bake chip for 24 to 48 hours at 125 c to 150 c with power off read and check program figure 19-6 recommended screening procedure if a series of programming errors occurs while the same prom programmer is being used, stop programming and check the prom programmer and socket adapter for defects. please inform renesas technology of any abnormal conditions noted during or after programming or in screening of program data after high-temperature baking. rev.6.00 oct.28.2004 page 574 of 1016 rej09b0138-0600h 19.6 overview of flash memory (h8s/2357 f-ztat) 19.6.1 features the features of the flash memory are summarized below. four flash memory operating modes ? program mode ? erase mode ? program-verify mode ? erase-verify mode programming/erase methods the flash memory is programmed 32 bytes at a time. erasing is performed by block erase (in single-block units). when erasing multiple blocks, the individual blocks must be erased sequentially. block erasing can be performed as required on 1-kbyte, 8-kbyte, 16-kbyte, 28-kbyte, and 32-kbyte blocks. programming/erase times (5 v version) the flash memory programming time is 10 ms (typ.) for simultaneous 32-byte programming, equivalent to 300 m s (typ.) per byte, and the erase time is 100 ms (typ.) per block. reprogramming capability the flash memory can be reprogrammed up to 100 times. on-board programming modes there are two modes in which flash memory can be programmed/erased/verified on-board ? boot mode ? user program mode automatic bit rate adjustment with data transfer in boot mode, the bit rate of the h8s/2357 group chip can be automatically adjusted to match the transfer bit rate of the host. flash memory emulation by ram part of the ram area can be overlapped onto flash memory, to emulate flash memory updates in real time. protect modes there are three protect modes, hardware, software, and error protect, which allow protected status to be designated for flash memory program/erase/verify operations. programmer mode flash memory can be programmed/erased in programmer mode, using a prom programmer, as well as in on-board programming mode. rev.6.00 oct.28.2004 page 575 of 1016 rej09b0138-0600h 19.6.2 block diagram module bus bus

reset-start is executed, the mcu enters one of the operating modes shown in figure 19-8. in user mode, flash memory can be read but not programmed or erased. flash memory can be programmed and erased

pins have been set to boot mode, the boot program built into the mcu is started and the programming control program prepared in the host is serially transmitted to the mcu via the sci. in the mcu, the programming control program received via the sci is written into the programming control program area in on-chip ram. after the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). the transferred programming control program must therefore include coding that follows the programming algorithm given later. the system configuration in boot mode is shown in figure 19-14, and the boot program mode execution procedure in figure 19-15. rxd1 txd1 sci1 h8s/2357 chip flash memory write data reception verify data transmission host on-chip ram figure 19-14 system configuration in boot mode rev.6.00 oct.28.2004 page 589 of 1016 rej09b0138-0600h note: if a memory cell does not operate normally and cannot be erased, one h'ff byte is transmitted as an erase error, and the erase operation and subsequent operations are halted. start set pins to boot mode and execute reset-start host transfers data (h'00) continuously at prescribed bit rate mcu measures low period of h'00 data transmitted by host mcu calculates bit rate and sets value in bit rate register after bit rate adjustment, mcu transmits one h'00 data byte to host to indicate end of adjustment host confirms normal reception of bit rate adjustment end indication (h'00), and transmits one h'55 data byte after receiving h'55, mcu transmits one h'aa data byte to host host transmits number of programming control program bytes (n), upper byte followed by lower byte mcu transmits received number of bytes to host as verify data (echo-back) n = 1 host transmits programming control program sequentially in byte units mcu transmits received programming control program to host as verify data (echo-back) transfer received programming control program to on-chip ram n = n?

transmission bit rate and the mcu? system clock frequency, there will be a discrepancy between the bit rates of the host and the mcu. to ensure correct sci operation, the host? transfer bit rate should be set to (4,800, or 9,600) bps. table 19-15 shows typical host transfer bit rates and system clock frequencies for which automatic adjustment of the mcu? bit rate is possible. the boot program should be executed within this system clock range. table 19-15 system clock frequencies for which automatic adjustment of h8s/2357 bit rate is possible host bit rate system clock frequency for which automatic adjustment of h8s/2357 bit rate is possible 9600 bps 8 to 20 mhz 4800 bps 4 to 20 mhz on-chip ram area divisions in boot mode: in boot mode, the 2 kbytes area from h'ffdc00 to h'ffe3ff is reserved for use by the boot program, as shown in figure 19-17. the area to which the programming control program is transferred is h'ffe400 to h'fffb7f. the boot program area can be used when the programming control program transferred into ram enters the execution state. a stack area should be set up as required. rev.6.00 oct.28.2004 page 591 of 1016 rej09b0138-0600h h'ffdc00 h'ffe3ff programming control program area (6 kbytes) h'fffbff h'fffb7f boot program area * 1 (2 kbytes) (128 bytes) * 2 notes: 1. the boot program area cannot be used until a transition is made to the execution state for the programming control program transferred to ram. note that the boot program remains stored in this area after a branch is made to the programming control program. 2. the area from h'fffb80 to h'fffbff (128 bytes) is used by the boot program. the area from h'ffe400 to h'fffb7f can be used by the programming control program. figure 19-17 ram areas in boot mode notes on use of user mode: when the chip comes out of reset in boot mode, it measures the low-level period of the input at the sci? rxd1 pin. the reset should end with rxd1 high. after the reset ends, it takes approximately 100 states before the chip is ready to measure the low-level period of the rxd1 pin. in boot mode, if any data has been programmed into the flash memory (if all data is not 1), all flash memory blocks are erased. boot mode is for use when user program mode is unavailable, such as the first time on-board programming is performed, or if the program activated in user program mode is accidentally erased. interrupts cannot be used while the flash memory is being programmed or erased. the rxd1 and txd1 pins should be pulled up on the board. before branching to the programming control program (ram area h'ffe400), the chip terminates transmit and receive operations by the on-chip sci (channel 1) (by clearing the re and te bits in scr to 0), but the adjusted bit rate value remains set in brr. the transmit data output pin, txd1, goes to the high-level output state (p31ddr = 1, p31dr = 1). the contents of the cpu? internal general registers are undefined at this time, so these registers must be initialized immediately after branching to the programming control program. in particular, since the stack pointer (sp) is used implicitly in subroutine calls, etc., a stack area must be specified for use by the programming control program. initial settings must also be made for the other on-chip registers. boot mode can be entered by making the pin settings shown in table 19-14 and executing a reset-start. boot mode can be cleared by driving the reset pin low, waiting at least 20 states, then setting the fwe pin and mode pins, and executing reset release* 1 . boot mode can also be cleared by a wdt overflow reset. do not change the mode pin input levels in boot mode, and do not drive the fwe pin low while the boot program is being executed or while flash memory is being programmed or erased* 2 . rev.6.00 oct.28.2004 page 592 of 1016 rej09b0138-0600h if the mode pin input levels are changed (for example, from low to high) during a reset, the state of ports with multiplexed address functions and bus control output pins ( as , rd , hwr ) will change according to the change in the microcomputer? operating mode* 3 . therefore, care must be taken to make pin settings to prevent these pins from becoming output signal pins during a reset, or to prevent collision with signals outside the microcomputer. notes: 1. mode pins and fwe pin input must satisfy the mode programming setup time (t mds = 200 ns) with respect to the reset release timing, as shown in figures 19-33 to 19-35. 2. for further information on fwe application and disconnection, see section 19.14, flash memory programming and erasing precautions. 3. see appendix d, pin states. 19.8.2 user program mode when set to user program mode, the chip can program and erase its flash memory by executing a user program/erase control program. therefore, on-board reprogramming of the on-chip flash memory can be carried out by providing on- board means of fwe control and supply of programming data, and storing a program/erase control program in part of the program area as necessary. to select user program mode, select a mode that enables the on-chip flash memory (mode 6 or 7), and apply a high level to the fwe pin. in this mode, on-chip supporting modules other than flash memory operate as they normally would in modes 6 and 7. the flash memory itself cannot be read while the swe bit is set to 1 to perform programming or erasing, so the control program that performs programming and erasing should be run in on-chip ram or external memory. figure 19-18 shows the procedure for executing the program/erase control program when transferred to on-chip ram. rev.6.00 oct.28.2004 page 593 of 1016 rej09b0138-0600h clear fwe * fwe = high * branch to flash memory application program branch to program/erase control program in ram area execute program/erase control program (flash memory rewriting) transfer program/erase control program to ram md2, md1, md0 = 110, 111 reset-start write the fwe assessment program and transfer program (and the program/erase control program if necessary) beforehand notes: do not apply a constant high level to the fwe pin. apply a high level to the fwe pin only when the flash memory is programmed or erased. also, while a high level is applied to the fwe pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. * for further information on fwe application and disconnection, see section 19.14, flash memory programming and erasing precautions. figure 19-18 user program mode execution procedure rev.6.00 oct.28.2004 page 594 of 1016 rej09b0138-0600h 19.9 programming/erasing flash memory in the on-board programming modes, flash memory programming and erasing is performed by software, using the cpu. there are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. transitions to these modes can be made by setting the psu and esu bits in flmcr2, and the p, e, pv, and ev bits in flmcr1. the flash memory cannot be read while being programmed or erased. therefore, the program that controls flash memory programming/erasing (the programming control program) should be located and executed in on-chip ram or external memory. notes: 1. operation is not guaranteed if setting/resetting of the swe, ev, pv, e, and p bits in flmcr1, and the esu and psu bits in flmcr2, is executed by a program in flash memory. 2. when programming or erasing, set fwe to 1 (programming/erasing will not be executed if fwe = 0). 3. perform programming in the erased state. do not perform additional programming on previously programmed addresses. 19.9.1 program mode follow the procedure shown in the program/program-verify flowchart in figure 19-19 to write data or programs to flash memory. performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. programming should be carried out 32 bytes at a time. the wait times (x, y, z, a , ? g, e, h) after bits are set or cleared in flash memory control registers 1 and 2 (flmcr1, flmcr2) and the maximum number of programming operations (n) are shown in table 22.42 in section 22.7.6, flash memory characteristics. following the elapse of (x) m s or more after the swe bit is set to 1 in flash memory control register 1 (flmcr1), 32-byte program data is stored in the program data area and reprogram data area, and the 32-byte data in the reprogram data area written consecutively to the write addresses. the lower 8 bits of the first address written to must be h'00, h'20, h'40, h'60, h'80, h'a0, h'c0, or h'e0. thirty-two consecutive byte data transfers are performed. the program address and program data are latched in the flash memory. a 32-byte data transfer must be performed even if writing fewer than 32 bytes; in this case, h'ff data must be written to the extra addresses. next, the watchdog timer is set to prevent overprogramming in the event of program runaway, etc. set a value greater than (y + z + a + ? m s as the wdt overflow period. after this, preparation for program mode (program setup) is carried out by setting the psu bit in flmcr2, and after the elapse of (y) m s or more, the operating mode is switched to program mode by setting the p bit in flmcr1. the time during which the p bit is set is the flash memory programming time. make a program setting so that the time for one programming operation is within the range of (z) m s. 19.9.2 program-verify mode in program-verify mode, the data written in program mode is read to check whether it has been correctly written in the flash memory. after the elapse of a given programming time, the programming mode is exited (the p bit in flmcr1 is cleared to 0, then the psu bit in flmcr2 is cleared to 0 at least ( a ) m s later). next, the watchdog timer is cleared after the elapse of ( b ) m s or more, and the operating mode is switched to program-verify mode by setting the pv bit in flmcr1. before reading in program-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of ( g ) m s or more. when the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. wait at least ( e ) m s after the dummy write before performing this read operation. next, the originally written data is compared with the verify data, and reprogram data is computed (see figure rev.6.00 oct.28.2004 page 595 of 1016 rej09b0138-0600h 19-19) and transferred to the reprogram data area. after 32 bytes of data have been verified, exit program-verify mode, wait for at least ( h ) m s, then clear the swe bit in flmcr1 to 0. if reprogramming is necessary, set program mode again, and repeat the program/program-verify sequence as before. however, ensure that the program/program-verify sequence is not repeated more than (n) times on the same bits. set swe bit in flmcr1 wait (x) m s n = 1 m = 0 write 32-byte data in ram reprogram data area consecutively to flash memory enable wdt set psu bit in flmcr2 wait (y) m s set p bit in flmcr1 wait (z) m s start of programming clear p bit in flmcr1 wait ( a ) m s wait ( b ) m s ng ng ng ng ok ok ok wait ( g ) m s wait ( e ) m s * 5 * 3 * 4 * 2 * 5 * 5 * 5 * 5 * 5 * 5 * 5 store 32-byte program data in program data area and reprogram data area * 4 * 1 * 3 * 5 wait ( h ) m s clear psu bit in flmcr2 disable wdt set pv bit in flmcr1 h'ff dummy write to verify address read verify data reprogram data computation clear pv bit in flmcr1 clear swe bit in flmcr1 m = 1 end of programming program data = verify data?

m s as the wdt overflow period. after this, preparation for erase mode (erase setup) is carried out by setting the esu bit in flmcr2, and after the elapse of (y) m s or more, the operating mode is switched to erase mode by setting the e bit in flmcr1. the time during which the e bit is set is the flash memory erase time. ensure that the erase time does not exceed (z) ms. note: with flash memory erasing, preprogramming (setting all data in the memory to be erased to 0) is not necessary before starting the erase procedure. 19.9.4 erase-verify mode in erase-verify mode, data is read after memory has been erased to check whether it has been correctly erased. after the elapse of the erase time, erase mode is exited (the e bit in flmcr1 is cleared to 0, then the esu bit in flmcr2 is cleared to 0 at least ( a ) m s later), the watchdog timer is cleared after the elapse of ( b ) m s or more, and the operating mode is switched to erase-verify mode by setting the ev bit in flmcr1. before reading in erase-verify mode, a dummy write of h'ff data should be made to the addresses to be read. the dummy write should be executed after the elapse of ( g ) m s or more. when the flash memory is read in this state (verify data is read in 16-bit units), the data at the latched address is read. wait at least ( e ) m s after the dummy write before performing this read operation. if the read data has been erased (all 1), a dummy write is performed to the next address, and erase-verify is performed. if the read data has not been erased, set erase mode again, and repeat the erase/erase-verify sequence in the same way. however, ensure that the erase/erase- verify sequence is not repeated more than (n) times. when verification is completed, exit erase-verify mode, and wait for at least ( h ) m s. if erasure has been completed on all the erase blocks, clear the swe bit in flmcr1 to 0. if there are any unerased blocks, make a 1 bit setting in ebr1 or ebr2 for the flash memory area to be erased, and repeat the erase/erase- verify sequence in the same way. rev.6.00 oct.28.2004 page 597 of 1016 rej09b0138-0600h end of erasing start set swe bit in flmcr1 set esu bit in flmcr2 set e bit in flmcr1 wait (x) m s wait (y) m s n = 1 set ebr1, ebr2 enable wdt * 2 * 2 * 4 wait (z) ms * 2 wait ( a ) m s * 2 wait ( b ) m s * 2 wait ( g ) m s set block start address to verify address * 2 wait ( e ) m s * 2 * 3 * 2 wait ( h ) m s * 2 * 2 * 5 start of erase clear e bit in flmcr1 clear esu bit in flmcr2 set ev bit in flmcr1 h'ff dummy write to verify address read verify data clear ev bit in flmcr1 wait ( h ) m s clear ev bit in flmcr1 clear swe bit in flmcr1 disable wdt halt erase * 1 verify data = all 1?

(see table 19-16.) table 19-16 hardware protection functions item description program erase fwe pin protection when a low level is input to the fwe pin, flmcr1, flmcr2 (excluding the fler bit), ebr1, and ebr2 are initialized, and the program/erase-protected state is entered. yes yes reset/standby protection in a reset (including a wdt overflow reset) and in standby mode, flmcr1, flmcr2, ebr1, and ebr2 are initialized, and the program/erase-protected state is entered. in a reset via the res pin, the reset state is not entered unless the res pin is held low until oscillation stabilizes after powering on. in the case of a reset during operation, hold the res pin low for the res pulse width specified in the ac characteristics section. yes yes rev.6.00 oct.28.2004 page 599 of 1016 rej09b0138-0600h 19.10.2 software protection software protection can be implemented by setting the swe bit in flmcr1, erase block registers 1 and 2 (ebr1, ebr2), and the rams bit in ramer. when software protection is in effect, setting the p or e bit in flash memory control register 1 (flmcr1) does not cause a transition to program mode or erase mode. (see table 19-17.) table 19-17 software protection functions item description program erase swe bit protection clearing the swe bit to 0 in flmcr1 sets the program/erase-protected state for all blocks. (execute in on-chip ram or external memory.) yes yes block specification protection erase protection can be set for individual blocks by settings in erase block registers 1 and 2 (ebr1, ebr2). setting ebr1 and ebr2 to h'00 places all blocks in the erase-protected state. ? yes emulation protection setting the rams bit to 1 in the ram emulation register (ramer) places all blocks in the program/erase-protected state. yes yes 19.10.3 error protection in error protection, an error is detected when mcu runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. if the mcu malfunctions during flash memory programming/erasing, the fler bit is set to 1 in flmcr2 and the error protection state is entered. the flmcr1, flmcr2, ebr1, and ebr2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. program mode or erase mode cannot be re-entered by re-setting the p or e bit. however, pv and ev bit setting is enabled, and a transition can be made to verify mode. fler bit setting conditions are as follows: when flash memory is read during programming/erasing (including a vector read or instruction fetch) immediately after exception handling (excluding a reset) during programming/erasing when a sleep instruction (including software standby) is executed during programming/erasing when the cpu loses the bus during programming/erasing error protection is released only by a reset and in hardware standby mode. figure 19-21 shows the flash memory state transition diagram. rev.6.00

releasing ram overlap. 4. the data written in the overlapping ram is written into the flash memory space (eb1). notes: 1. when the rams bit is set to 1, program/erase protection is enabled for all blocks regardless of the value of ram1 and ram0 (emulation protection). in this state, setting the p or e bit in flash memory control register 1 (flmcr1) will not cause a transition to program mode or erase mode. when actually programming a flash memory area, the rams bit should be cleared to 0. 2. a ram area cannot be erased by execution of software in accordance with the erase algorithm while flash memory emulation in ram is being used. 3. block area eb0 includes the vector table. when performing ram emulation, the vector table is needed by the overlap ram. rev.6.00 oct.28.2004 page 603 of 1016 rej09b0138-0600h 19.12 interrupt handling when programming/erasing flash memory all interrupts, including nmi interrupt is disabled when flash memory is being programmed or erased (when the p or e bit is set in flmcr1), and while the boot program is executing in boot mode* 1 , to give priority to the program or erase operation. there are three reasons for this: 1. interrupt during programming or erasing might cause a violation of the programming or erasing algorithm, with the result that normal operation could not be assured. 2. in the interrupt exception handling sequence during programming or erasing, the vector would not be read correctly* 2 , possibly resulting in mcu runaway. 3. if interrupt occurred during boot program execution, it would not be possible to execute the normal boot mode sequence. for these reasons, in on-board programming mode alone there are conditions for disabling interrupt, as an exception to the general rule. however, this provision does not guarantee normal erasing and programming or mcu operation. all requests, including nmi interrupt, must therefore be restricted inside and outside the mcu when programming or erasing flash memory. nmi interrupt is also disabled in the error-protection state while the p or e bit remains set in flmcr1. notes: 1. interrupt requests must be disabled inside and outside the mcu until the programming control program has completed programming. 2. the vector may not be read correctly in this case for the following two reasons: ? if flash memory is read while being programmed or erased (while the p or e bit is set in flmcr1), correct read data will not be obtained (undetermined values will be returned). ? if the interrupt entry in the vector table has not been programmed yet, interrupt exception handling will not be executed correctly. rev.6.00 oct.28.2004 page 604 of 1016 rej09b0138-0600h 19.13 flash memory programmer mode 19.13.1 programmer mode setting programs and data can be written and erased in programmer mode as well as in the on-board programming modes. in programmer mode, the on-chip rom can be freely programmed using a prom programmer that supports renesas technology microcomputer device types with 128-kbyte on-chip flash memory. flash memory read mode, auto-program mode, auto-erase mode, and status read mode are supported with this device type. in auto-program mode, auto-erase mode, and status read mode, a status polling procedure is used, and in status read mode, detailed internal signals are output after execution of an auto-program or auto-erase operation. table 19-18 shows programmer mode pin settings. table 19-18 programmer mode pin settings pin names settings/external circuit connection mode pins: md 2 , md 1 , md 0 low-level input mode

programming addresses which have previously been programmed, carry out auto-erasing before auto- programming. when performing programming using prom mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. notes: 1. the flash memory is initially in the erased state when the device is shipped by renesas technology. for other chips for which the erasure history is unknown, it is recommended that auto-erasing be executed to check and supplement the initialization (erase) level. 2. auto-programming should be performed once only on the same address block. 19.14 flash memory programming and erasing precautions precautions concerning the use of on-board programming mode, the ram emulation function, and prom mode are summarized below. use the specified voltages and timing for programming and erasing: applied voltages in excess of the rating can permanently damage the device. use a prom programmer that supports renesas technology microcomputer device types with 128-kbyte on-chip flash memory. do not select the hn28f101 setting for the prom programmer, and only use the specified socket adapter. incorrect use will result in damaging the device. powering on and off (see figures 19-33 to 19-35): do not apply a high level to the fwe pin until v cc has stabilized. also, drive the fwe pin low before turning off v cc . when applying or disconnecting v cc , fix the fwe pin low and place the flash memory in the hardware protection state. the power-on and power-off timing requirements should also be satisfied in the event of a power failure and subsequent recovery. fwe application/disconnection (see figures 19-33 to 19-35): fwe application should be carried out when mcu operation is in a stable condition. if mcu operation is not stable, fix the fwe pin low and set the protection state. the following points must be observed concerning fwe application and disconnection to prevent unintentional programming or erasing of flash memory: apply fwe when the v cc voltage has stabilized within its rated voltage range. apply fwe when oscillation has stabilized (after the elapse of the oscillation settling time). in boot mode, apply and disconnect fwe during a reset. rev.6.00 oct.28.2004 page 615 of 1016 rej09b0138-0600h in user program mode, fwe can be switched between high and low level regardless of the reset state. fwe input can also be switched during program execution in flash memory. do not apply fwe if program runaway has occurred. disconnect fwe only when the swe, esu, psu, ev, pv, p, and e bits in flmcr1 and flmcr2 are cleared. make sure that the swe, esu, psu, ev, pv, p, and e bits are not set by mistake when applying or disconnecting fwe. do not apply a constant high level to the fwe pin: apply a high level to the fwe pin only when programming or erasing flash memory. a system configuration in which a high level is constantly applied to the fwe should be avoided. also, while a high level is applied to the fwe pin, the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. use the recommended algorithm when programming and erasing flash memory: the recommended algorithm enables programming and erasing to be carried out without subjecting the device to voltage stress or sacrificing program data reliability. when setting the p or e bit in flmcr1, the watchdog timer should be set beforehand as a precaution against program runaway, etc. do not set or clear the swe bit during program execution in flash memory: clear the swe bit before executing a program or reading data in flash memory. when the swe bit is set, data in flash memory can be rewritten, but flash memory should only be accessed for verify operations (verification during programming/erasing). similarly, when using the ram emulation function while a high level is being input to the fwe pin, the swe bit must be cleared before executing a program or reading data in flash memory. however, the ram area overlapping flash memory space can be read and written to regardless of whether the swe bit is set or cleared. do not use interrupts while flash memory is being programmed or erased: all interrupt requests, including nmi, should be disabled during fwe application to give priority to program/erase operations. do not perform additional programming. erase the memory before reprogramming. in on-board programming, perform only one programming operation on a 32-byte programming unit block. in prom mode, too, perform only one programming operation on a 128-byte programming unit block. programming should be carried out with the entire programming unit block erased. before programming, check that the chip is correctly mounted in the prom programmer. overcurrent damage to the device can result if the index marks on the prom programmer socket, socket adapter, and chip are not correctly aligned. do not touch the socket adapter or chip during programming. touching either of these can cause contact faults and write errors. rev.6.00 oct.28.2004 page 616 of 1016 rej09b0138-0600h flash memory access disabled

the flash memory are summarized below. four flash memory operating modes ? program mode ? erase mode ? program-verify mode ? erase-verify mode programming/erase methods the flash memory is programmed 128 bytes at a time. erasing is performed by block erase (in single-block units). to erase the entire flash memory, the individual blocks must be erased sequentially. block erasing can be performed as required on 4-kbyte, 32-kbyte, and 64-kbyte blocks. programming/erase times the flash memory programming time is 10 ms (typ.) for simultaneous 128-byte programming, equivalent to 78 m s (typ.) per byte, and the erase time is 50 ms (typ.). reprogramming capability depending on the product, the maximum number of times the flash memory can be reprogrammed is either 100 or 1,000. ? reprogrammable up to 100 times: hd64f2398te, hd64f2398f ? reprogrammable up to 1,000 times: hd64f2398tet, hd64f2398ft on-board programming modes there are two modes in which flash memory can be programmed/erased/verified on-board: ? boot mode ? user program mode automatic bit rate adjustment with data transfer in boot mode, the bit rate of the chip can be automatically adjusted to match the transfer bit rate of the host. flash memory emulation by ram part of the ram area can be overlapped onto flash memory, to emulate flash memory updates in real time. protect modes there are three protect modes, hardware, software, and error protect, which allow protected status to be designated for flash memory program/erase/verify operations. programmer mode flash memory can be programmed/erased in programmer mode, using a prom programmer, as well as in on-board programming mode. rev.6.00 oct.28.2004 page 620 of 1016 rej09b0138-0600h 19.15.2 overview block diagram module bus

pins have been set to boot mode, the boot program built into the chip is started and the programming control program prepared in the host is serially transmitted to the chip via the sci. in the chip, the programming control program received via the sci is written into the programming control program area in on-chip ram. after the transfer is completed, control branches to the start address of the programming control program area and the programming control program execution state is entered (flash memory programming is performed). the transferred programming control program must therefore include coding that follows the programming algorithm given later. the system configuration in boot mode is shown in figure 19-43, and the boot program mode execution procedure in figure 19-44. rxd1 txd1 sci1 chip flash memory write data reception verify data transmission host on-chip ram figure 19-43 system configuration in boot mode rev.6.00 oct.28.2004 page 634 of 1016 rej09b0138-0600h note: if a memory cell does not operate normally and cannot be erased, one h'ff byte is transmitted as an erase error, and the erase operation and subsequent operations are halted. start set pins to boot mode and execute reset-start host transfers data (h'00) continuously at prescribed bit rate chip measures low period of h'00 data transmitted by host chip calculates bit rate and sets value in bit rate register after bit rate adjustment, chip transmits one h'00 data byte to host to indicate end of adjustment host confirms normal reception of bit rate adjustment end indication (h'00), and transmits one h'55 data byte after receiving h'55, chip transmits one h'aa data byte to host host transmits number of programming control program bytes (n), upper byte followed by lower byte chip transmits received number of bytes to host as verify data (echo-back) n = 1 host transmits programming control program sequentially in byte units chip transmits received programming control program to host as verify data (echo-back) transfer received programming control program to on-chip ram n = n?

transmission bit rate and the chip? system clock frequency, there will be a discrepancy between the bit rates of the host and the chip. to ensure correct sci operation, the host? transfer bit rate should be set to 9,600 or 19,200 bps. table 19-36 shows typical host transfer bit rates and system clock frequencies for which automatic adjustment of the mcu?

rxd1 pin. the reset should end with rxd1 high. after the reset ends, it takes approximately 100 states before the chip is ready to measure the low-level period of the rxd1 pin. in boot mode, if any data has been programmed into the flash memory (if all data is not 1), all flash memory blocks are erased. boot mode is for use when user program mode is unavailable, such as the first time on-board programming is performed, or if the program activated in user program mode is accidentally erased. interrupts cannot be used while the flash memory is being programmed or erased. the rxd1 and txd1 pins should be pulled up on the board. before branching to the programming control program (ram area h'ffe400 to h'fffbff), the chip terminates transmit and receive operations by the on-chip sci (channel 1) (by clearing the re and te bits in scr to 0), but the adjusted bit rate value remains set in brr. the transmit data output pin, txd1, goes to the high-level output state (p31ddr = 1, p31dr = 1). the contents of the cpu? internal general registers are undefined at this time, so these registers must be initialized immediately after branching to the programming control program. in particular, since the stack pointer (sp) is used implicitly in subroutine calls, etc., a stack area must be specified for use by the programming control program. initial settings must also be made for the other on-chip registers. boot mode can be entered by making the pin settings shown in table 19-35 and executing a reset-start. boot mode can be cleared by driving the reset pin low, waiting at least 20 states, then setting the mode pins, and executing reset release* 1 . boot mode can also be cleared by a wdt overflow reset. rev.6.00 oct.28.2004 page 637 of 1016 rej09b0138-0600h do not change the mode pin input levels in boot mode. if the mode pin input levels are changed (for example, from low to high) during a reset, the state of ports with multiplexed address functions and bus control output pins ( as , rd , hwr ) will change according to the change in the microcomputer? operating mode* 2 . therefore, care must be taken to make pin settings to prevent these pins from becoming output signal pins during a reset, or to prevent collision with signals outside the microcomputer. notes: 1. mode pins input must satisfy the mode programming setup time (t mds = 200 ns) with respect to the reset release timing. 2. see appendix d, pin states. 19.17.2 user program mode when set to user program mode, the chip can program and erase its flash memory by executing a user program/erase control program. therefore, on-board reprogramming of the on-chip flash memory can be carried out by providing on- board means supply of programming data, and storing a program/erase control program in part of the program area if necessary. to select user program mode, select a mode that enables the on-chip flash memory (mode 6 or 7). in this mode, on-chip supporting modules other than flash memory operate as they normally would in modes 6 and 7. the flash memory itself cannot be read while the swe bit is set to 1 to perform programming or erasing, so the control program that performs programming and erasing should be run in on-chip ram or external memory. when the program is located in external memory, an instruction for programming the flash memory and the following instruction should be located in on-chip ram. figure 19-47 shows the procedure for executing the program/erase control program when transferred to on-chip ram. branch to flash memory application program branch to program/erase control program in ram area execute program/erase control program (flash memory rewriting) transfer program/erase control program to ram md2, md1, md0 = 110, 111 reset-start write the transfer program (and the program/erase control program if necessary) beforehand note: the watchdog timer should be activated to prevent overprogramming or overerasing due to program runaway, etc. figure 19-47 user program mode execution procedure rev.6.00 oct.28.2004 page 638 of 1016 rej09b0138-0600h 19.18 programming/erasing flash memory in the on-board programming modes, flash memory programming and erasing is performed by software, using the cpu. there are four flash memory operating modes: program mode, erase mode, program-verify mode, and erase-verify mode. transitions to these modes can be made by setting the psu, esu, p, e, pv, and ev bits in flmcr1. the flash memory cannot be read while being programmed or erased. therefore, the program that controls flash memory programming/erasing (the programming control program) should be located and executed in on-chip ram or external memory. when the program is located in external memory, an instruction for programming the flash memory and the following instruction should be located in on-chip ram. the dmac or dtc should not be activated before or after the instruction for programming the flash memory is executed. notes: 1. operation is not guaranteed if setting/resetting of the swe, esu, psu, ev, pv, e, and p bits in flmcr1 is executed by a program in flash memory. 2. perform programming in the erased state. do not perform additional programming on previously programmed addresses. 19.18.1 program mode follow the procedure shown in the program/program-verify flowchart in figure 19-48 to write data or programs to flash memory. performing program operations according to this flowchart will enable data or programs to be written to flash memory without subjecting the device to voltage stress or sacrificing program data reliability. programming should be carried out 128 bytes at a time. for the wait times (x, y, z1, z2, z3 a , ?

(see table 19-37.) table 19-37 hardware protection functions item description program erase reset/standby protection in a reset (including a wdt overflow reset) and in standby mode, flmcr1, flmcr2, ebr1, and ebr2 are initialized, and the program/erase-protected state is entered. in a reset via the res pin, the reset state is not entered unless the res pin is held low until oscillation stabilizes after powering on. in the case of a reset during operation, hold the res pin low for the res pulse width specified in the ac characteristics section. yes yes rev.6.00 oct.28.2004 page 643 of 1016 rej09b0138-0600h 19.19.2 software protection software protection can be implemented by setting the swe bit in flash memory control register 1 (flmcr1), erase block registers 1 and 2 (ebr1, ebr2), and the rams bit in the ram emulation register (ramer). when software protection is in effect, setting the p or e bit in flmcr1 does not cause a transition to program mode or erase mode. (see table 19-38.) table 19-38 software protection functions item description program erase swe bit protection clearing the swe bit to 0 in flmcr1 sets the program/erase-protected state for all blocks (execute in on-chip ram or external memory.) yes yes block specification protection erase protection can be set for individual blocks by settings in erase block registers 1 and 2 (ebr1, ebr2). setting ebr1 and ebr2 to h'00 places all blocks in the erase-protected state. ? yes emulation protection setting the rams bit to 1 in the ram emulation register (ramer) places all blocks in the program/erase-protected state. yes yes rev.6.00 oct.28.2004 page 644 of 1016 rej09b0138-0600h 19.19.3 error protection in error protection, an error is detected when mcu runaway occurs during flash memory programming/erasing, or operation is not performed in accordance with the program/erase algorithm, and the program/erase operation is aborted. aborting the program/erase operation prevents damage to the flash memory due to overprogramming or overerasing. if the mcu malfunctions during flash memory programming/erasing, the fler bit is set to 1 in flmcr2 and the error protection state is entered. the flmcr1, flmcr2, ebr1, and ebr2 settings are retained, but program mode or erase mode is aborted at the point at which the error occurred. program mode or erase mode cannot be re-entered by re-setting the p or e bit. however, pv and ev bit setting is enabled, and a transition can be made to verify mode. fler bit setting conditions are as follows: when flash memory is read during programming/erasing (including a vector read or instruction fetch) immediately after exception handling (excluding a reset) during programming/erasing when a sleep instruction (including software standby) is executed during programming/erasing when the cpu loses the bus during programming/erasing error protection is released only by a reset and in hardware standby mode. figure 19-50 shows the

(ramer) enables part of ram to be overlapped onto the flash memory area so that data to be written to flash memory can be emulated in ram in real time. after the ramer setting has been made, accesses can be made from the flash memory area or the ram area overlapping flash memory. emulation can be performed in user mode and user program mode. figure 19-51 shows an example of emulation of real-time

ram2, ram1, and ram0 in ramer to 1, 0, 0, 1, to overlap part of ram onto the area (eb1) for which real-time programming is required. 2. real-time programming is performed using the overlapping ram. 3. after the program data has been confirmed, the rams bit is cleared, releasing ram overlap. 4. the data written in the overlapping ram is written into the flash memory space (eb1). notes: 1. when the rams bit is set to 1, program/erase protection is enabled for all blocks regardless of the value of ram2, ram1, and ram0 (emulation protection). in this state, setting the p or e bit in flash memory control register 1 (flmcr1) will not cause a transition to program mode or erase mode. when actually programming a flash memory area, the rams bit should be cleared to 0. 2. a ram area cannot be erased by execution of software in accordance with the erase algorithm while flash memory emulation in ram is being used. 3. block area eb0 includes the vector table. when performing ram emulation, the vector table is needed by the overlap ram. rev.6.00 oct.28.2004 page 647 of 1016 rej09b0138-0600h 19.21 interrupt handling when programming/erasing flash memory all interrupts, including nmi input, are disabled when flash memory is being programmed or erased (when the p or e bit is set in flmcr1), and while the boot program is executing in boot mode* 1 , to give priority to the program or erase operation. there are three reasons for this: 1. interrupt during programming or erasing might cause a violation of the programming or erasing algorithm, with the result that normal operation could not be assured. 2. in the interrupt exception handling sequence during programming or erasing, the vector would not be read correctly* 2 , possibly resulting in mcu runaway. 3. if an interrupt occurred during boot program execution, it would not be possible to execute the normal boot mode sequence. for these reasons, in on-board programming mode alone there are conditions for disabling interrupts, as an exception to the general rule. however, this provision does not guarantee normal erasing and programming or mcu operation. all interrupt requests, including nmi, must therefore be restricted inside and outside the mcu when programming or erasing flash memory. the nmi interrupt is also disabled in the error-protection state while the p or e bit remains set in flmcr1. notes: 1. interrupt requests must be disabled inside and outside the mcu until the programming control program has completed programming. 2. the vector may not be read correctly in this case for the following two reasons: ? if flash memory is read while being programmed or erased (while the p or e bit is set in flmcr1), correct read data will not be obtained (undetermined values will be returned). ? if the interrupt entry in the vector table has not been programmed yet, interrupt exception handling will not be executed correctly. 19.22 flash memory programmer mode 19.22.1 programmer mode setting programs and data can be written and erased in programmer mode as well as in the on-board programming modes. in programmer mode, the on-chip rom can be freely programmed using a prom programmer that supports the renesas technology microcomputer device type with 256-kbyte on-chip flash memory (fztat256v5a). flash memory read mode, auto-program mode, auto-erase mode, and status read mode are supported with this device type. in auto-program mode, auto-erase mode, and status read mode, a status polling procedure is used, and in status read mode, detailed internal signals are output after execution of an auto-program or auto-erase operation. table 19-39 shows programmer mode pin settings. table 19-39 programmer mode pin settings pin names settings/external circuit connection mode pins:

addresses which have previously been programmed, carry out auto-erasing before auto- programming. when performing programming using prom mode on a chip that has been programmed/erased in an on-board programming mode, auto-erasing is recommended before carrying out auto-programming. notes: 1. the flash memory is initially in the erased state when the device is shipped by renesas technology. for other chips for which the erasure history is unknown, it is recommended that auto-erasing be executed to check and supplement the initialization (erase) level. 2. auto-programming should be performed once only on the same address block. additional programming cannot be carried out on address blocks that have already been programmed. 19.23 flash memory programming and erasing precautions precautions concerning the use of on-board programming mode, the ram emulation function, and programmer mode are summarized below. use the specified voltages and timing for programming and erasing: applied voltages in excess of the rating can permanently damage the device. use a prom programmer that supports the renesas technology microcomputer device type with 256-kbyte on-chip flash memory (fztat256v5a). do not select the hn27c4096 setting for the prom programmer, and only use the specified socket adapter. failure to observe these points may result in damage to the device. powering on and off: when applying or disconnecting v cc power, fix the res pin low and place the flash memory in the hardware protection state. the power-on and power-off timing requirements should also be satisfied in the event of a power failure and subsequent recovery. use the recommended algorithm when programming and erasing flash memory: the recommended algorithm enables programming and erasing to be carried out without subjecting the device to voltage stress or sacrificing program data reliability. when setting the p or e bit in flmcr1, the watchdog timer should be set beforehand as a precaution against program runaway, etc. do not set or clear the swe bit during execution of a program in flash memory: wait for at least 100 m s after clearing the swe bit before executing a program or reading data in flash memory. when the swe bit is set, data in flash memory can be rewritten, but when swe = 1, flash memory can only be read in program-verify or erase-verify mode. access flash memory only for verify operations (verification during programming/erasing). also, do not clear the swe bit during programming, erasing, or verifying. similarly, when using the ram emulation function the swe bit must be cleared before executing a program or reading data in flash memory. however, the ram area overlapping flash memory space can be read and written to regardless of whether the swe bit is set or cleared. do not use interrupts while flash memory is being programmed or erased: when flash memory is programmed or erased, all interrupt requests, including nmi, should be disabled to give priority to program/erase operations. do not perform additional programming. erase the memory before reprogramming: in on-board programming, perform only one programming operation on a 128-byte programming unit block. in programmer mode, too, perform only rev.6.00 oct.28.2004 page 659 of 1016 rej09b0138-0600h one programming operation on a 128-byte programming unit block. programming should be carried out with the entire programming unit block erased. before programming, check that the chip is correctly mounted in the prom programmer: overcurrent damage to the device can result if the index marks on the prom programmer socket, socket adapter, and chip are not correctly aligned. do not touch the socket adapter or chip during programming: touching either of these can cause contact faults and write errors. rev.6.00 oct.28.2004 page 660 of 1016 rej09b0138-0600h rev.6.00 oct.28.2004 page 661 of 1016 rej09b0138-0600h section 20 clock pulse generator 20.1 overview the h8s/2357 group

program execution state, the h8s/2357 group has five power-down modes in which operation of the cpu and oscillator is halted and power dissipation is reduced. low-power operation can be achieved by individually controlling the cpu, on-chip supporting modules, and so on. the h8s/2357 group operating modes are as follows: (1) high-speed mode (2) medium-speed mode (3) sleep mode (4) module stop mode (5) software standby mode (6) hardware standby mode of these, (2) to (6) are power-down modes. sleep mode is a cpu mode, medium-speed mode is a cpu and bus master mode, and module stop mode is an on-chip supporting module mode (including bus masters other than the cpu). a combination of these modes can be set. after a reset, the h8s/2357 group is in high-speed mode. table 21-1 shows the conditions for transition to the various modes, the status of the cpu, on-chip supporting modules, etc., and the method of clearing each mode. table 21-1 operating modes operating transition clearing

the cpu operates on the operating clock (?2, ?4, ?8, ?16, or ?32) specified by the sck2 to sck0 bits. the bus masters other than the cpu (the dmac and dtc) also operate in medium- speed mode. on-chip supporting modules other than the bus masters always operate on the high-speed clock (?. in medium-speed mode, a bus access is executed in the specified number of states with respect to the bus master operating clock. for example, if ?4 is selected as the operating clock, on-chip memory is accessed in 4 states, and internal i/o registers in 8 states. medium-speed mode is cleared by clearing all of bits sck2 to sck0 to 0. a transition is made to high-speed mode and medium-speed mode is cleared at the end of the current bus cycle. if a sleep instruction is executed when the ssby bit in sbycr is cleared to 0, a transition is made to sleep mode. when sleep mode is cleared by an interrupt, medium-speed mode is restored. if a sleep instruction is executed when the ssby bit in sbycr is set to 1, a transition is made to software standby mode. when software standby mode is cleared by an external interrupt, medium-speed mode is restored. when the res pin is driven low, a transition is made to the reset state, and medium-speed mode is cleared. the same applies in the case of a reset caused by overflow of the watchdog timer. when the stby pin is driven low, a transition is made to hardware

in sleep mode, cpu operation stops but the contents of the cpu?s internal registers are retained. other supporting modules do not stop. sleep mode is cleared by a reset or any interrupt, and the cpu returns to the normal program execution state via the exception handling state. sleep mode is not cleared if interrupts are disabled, or if interrupts other than nmi are masked by the cpu. when the

for individual on-chip supporting modules. when the corresponding mstp bit in mstpcr is set to 1, module operation stops at the end of the bus cycle and a transition is made to module stop mode. the cpu continues operating independently. table 21-3 shows mstp bits and the corresponding on-chip supporting modules. when the corresponding mstp bit is cleared to 0, module stop mode is cleared and the module starts operating at the end of the bus cycle. in module stop mode, the internal states of modules other than the sci and a/d converter are retained. after reset clearance, all modules other than dmac and dtc are in module stop mode. when an on-chip supporting module is in module stop mode, read/write access to its registers is disabled. do not make a transition to sleep mode with mstpcr set to h'ffff or h'efff, as this will halt operation of the bus controller. table 21-3 mstp bits and corresponding on-chip supporting modules register bit module mstpcrh mstp15 dma controller (dmac)

dmac or dtc, the mstp15 and mstp14 bits may not be set to 1. setting of the dmac or dtc module stop mode should be carried out only when the respective module is not activated. for details, refer to section 7, dma controller, and section 8, data transfer controller. on-chip supporting module interrupt: relevant interrupt operations cannot be performed in module stop mode. consequently, if module stop mode is entered when an interrupt has been requested, it will not be possible to clear the cpu interrupt source or the dmac or dtc activation source. interrupts should therefore be disabled before entering module stop mode. writing to mstpcr: mstpcr should only be written to by the cpu. rev.6.00 oct.28.2004 page 675 of 1016 rej09b0138-0600h 21.6 software standby mode 21.6.1 software standby mode if a sleep instruction is executed when the ssby bit in sbycr is set to 1, software standby mode is entered. in this mode, the cpu, on-chip supporting modules, and oscillator all stop. however, the contents of the cpu? internal registers, ram data, and the states of on-chip supporting modules other than the sci and a/d converter, and i/o ports, are retained. whether the address bus and bus control signals are placed in the high-impedance state or retain the output state can be specified by the ope bit in sbycr. in this mode the oscillator stops, and therefore power dissipation is significantly reduced. 21.6.2 clearing software standby mode software standby mode is cleared by an external interrupt (nmi pin, or pins irq0 to irq2 ), or by means of the res pin or stby pin. clearing with an interrupt when an nmi or irq0 to irq2 interrupt request signal is input, clock oscillation starts, and after the elapse of the time set in bits sts2 to sts0 in syscr, stable clocks are supplied to the entire h8s/2357 group chip, software standby mode is cleared, and interrupt exception handling is started. when clearing software standby mode with an irq0 to irq2 interrupt, set the corresponding enable bit to 1 and ensure that no interrupt with a higher priority than interrupts irq0 to irq2 is generated. software standby mode cannot be cleared if the interrupt has been masked on the cpu side or has been designated as a dtc activation source. clearing with the res pin when the res pin is driven low, clock oscillation is started. at the same time as clock oscillation starts, clocks are supplied to the entire h8s/2357 group chip. note that the res pin must be held low until clock oscillation stabilizes. when the res pin goes high, the cpu begins reset exception handling. clearing with the stby pin when the stby pin is driven low, a transition is made to hardware standby mode. 21.6.3 setting oscillation stabilization time after clearing software standby mode bits sts2 to sts0 in sbycr should be set as described below. using a crystal oscillator: set bits sts2 to sts0 so that the standby time is at least 8 ms (the oscillation stabilization time). rev.6.00 oct.28.2004 page 676 of 1016 rej09b0138-0600h table 21-4 shows the standby times for different operating frequencies and settings of bits sts2 to sts0. table 21-4 oscillation stabilization time

21-2 shows an example in which a transition is made to software standby mode at the falling edge on the nmi pin, and software standby mode is cleared at the rising edge on the nmi pin. in this example, an nmi interrupt is accepted with the nmieg bit in syscr cleared to 0 (falling edge specification), then the nmieg bit is set to 1 (rising edge specification), the ssby bit is set to 1, and a sleep instruction is executed, causing a transition to software standby mode. software standby mode is then cleared at the rising edge on the nmi pin. rev.6.00 oct.28.2004 page 677 of 1016

figure 21-2 software standby mode application example 21.6.5 usage notes i/o port status: in software standby mode, i/o port states are retained. if the ope bit is set to 1, the address bus and bus control signal output is also retained. therefore, there is no reduction in current dissipation for the output current when a high-level signal is output. current dissipation during oscillation stabilization wait period: current dissipation increases during the oscillation stabilization wait period. write data buffer function: the write data buffer function and software standby mode cannot be used at the same time. when the write data buffer function is used, the wdbe bit in bcrl should be cleared to 0 to cancel the write data buffer function before entering software standby mode. also check that external writes have finished, by reading external addresses, etc., before executing a sleep instruction to enter software standby mode. see section 6.9, write data buffer function, for details of the write data buffer function. rev.6.00 oct.28.2004 page 678 of 1016 rej09b0138-0600h 21.7 hardware standby mode 21.7.1 hardware standby mode when the stby pin is driven low, a transition is made to hardware standby mode from any mode. in hardware standby mode, all functions enter the reset state and stop operation, resulting in a significant reduction in power dissipation. as long as the prescribed voltage is supplied, on-chip ram data is retained. i/o ports are set to the high-impedance state. in order to retain on-chip ram data, the rame bit in syscr should be cleared to 0 before driving the stby pin low. do not change the state of the mode pins (md 2 to md 0 ) while the h8s/2357 group is in hardware standby mode. hardware standby mode is cleared by means of the stby pin and the res pin. when the stby pin is driven high while the res pin is low, the reset state is set and clock oscillation is started. ensure that the res pin is held low until the clock oscillator stabilizes (at least 8 ms?the oscillation stabilization time?when using a crystal oscillator). when the res pin is subsequently driven high, a transition is made to the program execution state via the reset exception handling state. 21.7.2 hardware standby mode timing figure 21-3 shows an example of hardware standby mode timing. when the stby pin is driven low after the res pin has been driven low, a transition is made to hardware standby mode. hardware standby mode is cleared by driving the stby pin high, waiting for the oscillation stabilization time, then changing the res pin from low to high. oscillator res stby oscillation stabilization time reset exception handling figure 21-3 hardware standby mode timing (example) rev.6.00 oct.28.2004 page 679 of 1016 rej09b0138-0600h 21.8 ?clock output disabling function output of the ?clock can be controlled by means of the pstop bit in sckcr, and ddr for the corresponding port. when the pstop bit is set to 1, the ?clock stops at the end of the bus cycle, and ?output goes high. ?clock output is enabled when the pstop bit is cleared to 0. when ddr for the corresponding port is cleared to 0, ?clock output is disabled and input port mode is set. table 21-5 shows the state of the ?pin in each processing state. table 21-5 ?pin state in each processing state ddr 0 1 pstop 0 1 hardware standby mode high impedance software standby mode high

have a voltage step down circuit that automatically lowers the power supply voltage, inside the microcomputer, to an adequate level. a capacitor (one 0.47- m f capacitor or two 0.47- m f capacitors connected in parallel) should be connected between the v cl pin (a pin for internal voltage step down circuit) and v ss pin to stabilize the internal voltage. figure 22-32 shows how to connect the capacitor. do not connect the v cc power-supply to the v cl pin. doing so could permanently damage the lsi. (connect the v cc power-supply to the v cc pin, in the usual way.) v cl v ss do not connect the v cc power-supply to the v cl pin. doing so could permanently damage the lsi. (connect the v cc power-supply to the other v cc pin in the usual way.) use a multilayer ceramic capacitor (one 0.47- m f capacitor or two 0.47- m f capacitors connected in parallel) for this circuit, and place it/them near the v cl pin. an external capacitor to stabilize the internal voltage one 0.47- m f capacitor or two 0.47- m f capacitors connected in parallel figure 22-32 v cl capacitor

manual. however, actual electrical characteristics values, operation margins, and noise margins depend on differences in manufacturing processes, on-chip rom, or layout patterns. if the system is evaluated using the f-ztat version, perform the same evaluation test of the system using the masked rom version when switching to the masked rom version. 22.5 usage note (internal voltage step down for the h8s/2398 f-ztat) the h8s/2398 f-ztat have a voltage step down circuit that automatically lowers the power supply voltage, inside the microcomputer, to an adequate level. a capacitor (one 0.47- m f capacitor or two 0.47- m f capacitors connected in parallel) should be connected between the v cl pin (a pin for internal voltage step down circuit) and v ss pin to stabilize the internal voltage. figure 22-64 shows how to connect the capacitor. do not connect the v cc power-supply to the v cl pin. doing so could permanently damage the lsi. (connect the v cc power-supply to the v cc pin, in the usual way.) v cl v ss do not connect the v cc power-supply to the v cl pin. if connected, the lsi may be permanently damaged. connect the v cc power-supply to the other v cc pin in the usual way. use a multilayer ceramic capacitor (one 0.47- m f capacitor or two 0. 47- m f capacitors connected in parallel) for this circuit, and place it/them near the v cl pin. an external capacitor to stabilize the internal voltage one 0.47- m f capacitor or two 0.47- m f capacitors connected in parallel figure 22-64 v cl capacitor connection method

pin and nmi pin. the case in which pins settle* from an indeterminate state at power-on, and the case in which pins settle* from the high-impedance state, are described below. after reset release, power-on reset exception handling is started. note: * ?ettle?refers to the pin states in a power-on reset in each mcu operating mode. e.1 when pins settle from an indeterminate state at power-on when the nmi pin level changes from low to high after powering on, the chip goes to the power-on reset state* 2 after a high level is detected at the nmi pin. while the chip detects a low level at the nmi pin, the manual reset state* 1 is established. the pin states are indeterminate during this interval. (ports may output an internally determined value after powering on.) the nmi setup time (t nmis ) is necessary for the chip to detect a high level at the nmi pin. notes: 1. applies to the ztat version only. 2. except for the h8s/2357 ztat, all resets are power-on resets, regardless of the level on the nmi pin. v cc stby nmi res f power-on reset * 2 t osc1 nmi = low nmi = high res = low manual reset * 1 notes: 1. applies to the ztat version only. 2. except for the h8s/2357 ztat, all resets are power-on resets, regardless of the level on the nmi pin. figure e-1 when pins settle from an indeterminate state at power-on rev.6.00 oct.28.2004 page 1012 of 1016 rej09b0138-0600h e.2 when pins settle from the high-impedance state at power-on when the stby pin level changes from low to high after powering on, the chip goes to the power-on reset state* after a high level is detected at the stby pin. while the chip detects a low level at the stby pin, it is in the hardware standby mode. during this interval, the pins are in the high-impedance state. after detecting a high level at the stby pin, the chip starts oscillation. note: * excerpt for the h8s/2357 ztat, all resets are power-on resets, regardless of the level on the nmi pin. v cc nmi f power-on reset * 1 t osc1 nmi = high res = low t 1 confirm t 1 min and t nmis . * 2 hardware standby mode stby res notes: 1. applies to the ztat version only. 2. except for the h8s/2357 ztat, all resets are power-on resets, regardless of the level on the nmi pin. figure e-2 when pins settle from the high-impedance state at power-on rev.6.00 oct.28.2004 page 1013 of 1016 rej09b0138-0600h appendix f timing of transition to and recovery from hardware standby mode f.1 timing of transition to hardware standby mode (1) to retain ram contents with the rame bit set to 1 in syscr, drive the res signal low at least 10 system clock cycles before the stby signal goes low, as shown below. res must remain low until stby signal goes low (delay from stby low to res high: 0 ns or more). stby res t 2 0 ns t 1 10 t cyc figure f-1 timing of transition to hardware standby mode (2) to retain ram contents with the rame bit cleared to 0 in syscr, or when ram contents do not need to be retained, res does not have to be driven low as in (1). f.2 timing of recovery from hardware standby mode drive the res signal low and the nmi signal high approximately 100 ns or more before stby goes high to execute a power-on reset. stby res t osc t nmirh t 100 ns nmi figure f-2 timing of recovery from hardware standby mode rev.6.00 oct.28.2004 page 1014 of 1016 rej09b0138-0600h appendix g product code lineup table g.1 h8s/2357, h8s/2352 group product code lineup product type product code mark code package (hitachi package code) h8s/2357 masked rom hd6432357 hd6432357te 120-pin tqfp (tfp-120) hd6432357f 128-pin qfp (fp-128b) ztat hd6472357 hd6472357te 120-pin tqfp (tfp-120) hd6472357f 128-pin qfp (fp-128b) f-ztat hd64f2357 hd64f2357te 120-pin tqfp (tfp-120) hd64f2357f 128-pin qfp (fp-128b) h8s/2352 romless hd6412352 hd6412352te 120-pin tqfp (tfp-120) hd6412352f 128-pin qfp (fp-128b) table g.2 h8s/2398, h8s/2394, h8s/2392, h8s/2390 group product code lineup product type product code mark code package (hitachi package code) h8s/2398 masked rom hd6432398 hd6432398te * 1 120-pin tqfp (tfp-120) hd6432398f * 1 128-pin qfp (fp-128b) f-ztat hd64f2398 hd64f2398te * 1 120-pin tqfp (tfp-120) hd64f2398f * 1 128-pin qfp (fp-128b) hd64f2398tet 120-pin tqfp (tfp-120) hd64f2398ft 128-pin qfp (fp-128b) h8s/2394 romless hd6412394 hd6412394te * 1 120-pin tqfp (tfp-120) hd6412394f * 1 128-pin qfp (fp-128b) h8s/2392 romless hd6412392 hd6412392te 120-pin tqfp (tfp-120) hd6412392f 128-pin qfp (fp-128b) h8s/2390 romless hd6412390 hd6412390te 120-pin tqfp (tfp-120) hd6412390f 128-pin qfp (fp-128b) rev.6.00 oct.28.2004 page 1015 of 1016 rej09b0138-0600h appendix h package dimensions figures h-1 and h-2 show the tfp-120 and fp-128b package dimensions of the h8s/2357 group. package code jedec jeita mass (reference value) tfp-120 conforms 0.5 g * dimension including the plating thickness base material dimension 16.0 0.2 14 0.07 0.10 0.5 0.1 16.0 0.2 0.4 0.10 0.10 1.20 max * 0.17 0.05 0?
