single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 10 functional description central processing unit (cpu) the 7560 group uses the standard 740 family instruction set. re- fer to the table of 740 family addressing modes and machine instructions or the 740 family software manual for details on the instruction set. machine-resident 740 family instructions are as follows: the fst and slw instruction cannot be used. the stp, wit, mul, and div instruction can be used. the central processing unit (cpu) has six registers. figure 8 shows the 740 family cpu register structure. [accumulator (a)] the accumulator is an 8-bit register. data operations such as arithmetic data transfer, etc., are executed mainly through the ac- cumulator. [index register x (x)] the index register x is an 8-bit register. in the index addressing modes, the value of the operand is added to the contents of register x and specifies the real address. [index register y (y)] the index register y is an 8-bit register. in partial instruction, the value of the operand is added to the contents of register y and specifies the real address. [stack pointer (s)] the stack pointer is an 8-bit register used during subroutine calls and interrupts. this register indicates start address of stored area (stack) for storing registers during subroutine calls and interrupts. the low-order 8 bits of the stack address are determined by the contents of the stack pointer. the high-order 8 bits of the stack address are determined by the stack page selection bit. if the stack page selection bit is 0 , the high-order 8 bits becomes 00 16 . if the stack page selection bit is 1 , the high-order 8 bits becomes 01 16 . figure 9 shows the operations of pushing register contents onto the stack and popping them from the stack. table 6 shows the push and pop instructions of accumulator or processor status reg- ister. store registers other than those described in figure 9 with pro- gram when the user needs them during interrupts or subroutine calls. [program counter (pc)] the program counter is a 16-bit counter consisting of two 8-bit registers pc h and pc l . it is used to indicate the address of the next instruction to be executed. fig. 8 740 family cpu register structure a accumulator b7 b7 b7 b7 b0 b7b15 b0 b7 b0 b0 b0 b0 x index register x y index register y s stack pointer pc l program counter pc h n v t b d i z c processor status register (ps) carry flag zero flag interrupt disable flag decimal mode flag break flag index x mode flag overflow flag negative flag

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 12 [processor status register (ps)] the processor status register is an 8-bit register consisting of 5 flags which indicate the status of the processor after an arithmetic operation and 3 flags which decide mcu operation. branch opera- tions can be performed by testing the carry (c) flag , zero (z) flag, overflow (v) flag, or the negative (n) flag. in decimal mode, the z, v, n flags are not valid. bit 0: carry flag (c) the c flag contains a carry or borrow generated by the arith- metic logic unit (alu) immediately after an arithmetic operation. it can also be changed by a shift or rotate instruction. bit 1: zero flag (z) the z flag is set to 1 if the result of an immediate arithmetic op- eration or a data transfer is 0 , and set to 0 if the result is anything other than 0 . bit 2: interrupt disable flag (i) the i flag disables all interrupts except for the interrupt gener- ated by the brk instruction. interrupts are disabled when the i flag is 1 . bit 3: decimal mode flag (d) the d flag determines whether additions and subtractions are executed in binary or decimal. binary arithmetic is executed when this flag is 0 ; decimal arithmetic is executed when it is 1 . decimal correction is automatic in decimal mode. only the adc and sbc instructions can be used for decimal arithmetic. bit 4: break flag (b) the b flag is used to indicate that the current interrupt was gen- erated by the brk instruction. when the brk instruction is generated, the b flag is set to 1 automatically. when the other interrupts are generated, the b flag is set to 0 , and the proces- sor status register is pushed onto the stack. bit 5: index x mode flag (t) when the t flag is 0 , arithmetic operations are performed be- tween accumulator and memory. when the t flag is 1 , direct arithmetic operations and direct data transfers are enabled be- tween memory locations. bit 6: overflow flag (v) the v flag is used during the addition or subtraction of one byte of signed data. it is set to 1 if the result exceeds +127 to -128. when the bit instruction is executed, bit 6 of the memory loca- tion operated on by the bit instruction is stored in the v flag. bit 7: negative flag (n) the n flag is set to 1 if the result of an arithmetic operation or data transfer is negative. when the bit instruction is executed, bit 7 of the memory location operated on by the bit instruction is stored in the negative flag. table 7 instructions to set each bit of processor status register to ??or ? instruction setting to 1 instruction setting to 0 c flag sec clc z flag i flag sei cli d flag sed cld b flag t flag set clt v flag clv n flag

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 16 i/o ports direction registers the i/o ports (ports p0, p1, p2, p4, p5, p6, p7 1 p7 7 ) have direc- tion registers. ports p1 6 , p1 7 , p4, p5, p6, and p7 1 p7 7 can be set to input mode or output mode by each pin individually. p0 0 p0 7 and p1 0 -p1 5 are respectively set to input mode or output mode in a lump by bit 0 of the direction registers of ports p0 and p1 (see figure 13). when 0 is set to the bit corresponding to a pin, that pin becomes an input mode. when 1 is set to that bit, that pin becomes an output mode. if data is read from a port set to output mode, the value of the port latch is read, not the value of the pin itself. a port set to input mode is floating. if data is read from a port set to input mode, the value of the pin itself is read. if a pin set to input mode is written to, only the port latch is written to and the pin remains floating. port p3 output control register bit 0 of the port p3 output control register (address 0007 16 ) en- ables control of the output of ports p3 0 p3 7 . when the bit is set to 1 , the port output function is valid. when resetting, bit 0 of the port p3 output control register is set to 0 (the port output function is invalid) and pulled up. fig. 13 structure of port p0 direction register, port p1 direc- tion register fig. 14 structure of port p3 output control register p orts p 0 0 to p 0 7 di rect i on reg i ster 0 : input mode 1 : output mode not used (undefined at reading) (if writing to these bits, write 0 .) p ort p 0 di rect i on reg i ster (p0d : address 0001 16 ) b 7 b 0 n ote: i n ports set to output mo d e, t h e pu ll -up contro l bi t b ecomes invalid and pull-up resistor is not connected. p orts p 1 0 to p 1 5 di rect i on reg i ster 0 : input mode 1 : output mode not used (undefined at reading) (if writing to these bits, write 0 .) port p1 6 direction register port p1 7 direction register 0 : input mode 1 : output mode p ort p 1 di rect i on reg i ster (p1d : address 0003 16 ) b 7 b 0 p orts p 3 0 to p 3 7 output contro l bi t 0 : output function is invalid (pulled up) 1 : output function is valid (no pull up) not used (undefined at reading) (if writing to these bits, write 0 .) p ort p 3 output contro l reg i ster (p3c : address 0007 16 ) b 7 b 0 n o t e : i n p i n s s e t t o s e g m e n t o u t p u t b y s e g m e n t o u t p u t e n a b l e b i t s 0 , 1 ( b i t s 0 , 1 o f s e g m e n t o u t p u t e n a b l e r e g i s t e r ( a d d r e s s 3 8 1 6 ) ) , t h i s b i t b e c o m e s i n v a l i d a n d p u l l - u p r e s i s t o r i s n o t c o n n e c t e d .

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 29 timer x timer x is a 16-bit timer and is equipped with the timer latch. the division ratio of timer x is given by 1/(n+1), where n is the value in the timer latch. timer x is a down-counter. when the contents of timer x reach 0000 16 , an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. when the timer underflows, the timer x interrupt request bit is set to 1 . timer x can be selected in one of four modes by the timer x mode register and can be controlled the timer x write and the real time port. (1) timer mode the timer counts f(x in )/16 (or f(x cin )/16 in low-speed mode). (2) pulse output mode each time the timer underflows, a signal output from the cntr 0 pin is inverted. except for this, the operation in pulse output mode is the same as in timer mode. when using a timer in this mode, set the p5 4 /cntr 0 pin to output mode (set 1 to bit 4 of port p5 direction register). (3) event counter mode the timer counts signals input through the cntr 0 pin. except for this, the operation in event counter mode is the same as in timer mode. when using a timer in this mode, set the p5 4 / cntr 0 pin to input mode (set 0 to bit 4 of port p5 direction reg- ister). (4) pulse width measurement mode the count source is f(x in )/16 (or f(x cin )/16 in low-speed mode). if cntr 0 active edge switch bit is 0 , the timer counts while the input signal of cntr 0 pin is at h . if it is 1 , the timer counts while the input signal of cntr 0 pin is at l . when using a timer in this mode, set the p5 4 /cntr 0 pin to input mode (set 0 to bit 4 of port p5 direction register). read and write to timer x high-order, low-order registers when reading and writing to the timer x high-order and low-order registers, be sure to read/write both the timer x high- and low-or- der registers. when reading the timer x high-order and low-order registers, read the high-order register first. when writing to the timer x high-order and low-order registers, write the low-order register first. the timer x cannot perform the correct operation if the next operation is per- formed. write operation to the high- or low-order register before reading the timer x low-order register read operation from the high- or low-order register before writing to the timer x high-order register fig. 25 structure of timer x mode register t i m e r x m o d e r e g i s t e r ( t x m : a d d r e s s 0 0 2 7 1 6 ) ti mer x wr i te contro l bi t 0 : write value in latch and timer 1 : write value in latch only real time port control bit 0 : real time port function invalid 1 : real time port function valid rtp 0 data for real time port rtp 1 data for real time port timer x operating mode bits b5 b4 0 0 : timer mode 0 1 : pulse output mode 1 0 : event counter mode 1 1 : pulse width measurement mode cntr 0 active edge switch bit 0 : count at rising edge in event counter mode start from h output in pulse output mode measure h pulse width in pulse width measurement mode falling edge active for cntr 0 interrupt 1 : count at falling edge in event counter mode start from l output in pulse output mode measure l pulse width in pulse width measurement mode rising edge active for cntr 0 interrupt timer x stop control bit 0 : count start 1 : count stop b 7 b 0 timer x write control which write control can be selected by the timer x write control bit (bit 0) of the timer x mode register (address 0027 16 ), writing data to both the latch and the timer at the same time or writing data only to the latch. when the operation writing data only to the latch is selected, the value is set to the timer latch by writing data to the timer x register and the timer is updated at next underflow. after reset, the operation writing data to both the latch and the timer at the same time is selected, and the value is set to both the latch and the timer at the same time by writing data to the timer x register. the write operation is independent of timer x count operation, operating or stopping. when the value is written in latch only, a value is simultaneously set to the timer x and the timer x latch if the writing in the high- order register and the underflow of timer x are performed at the same timing. unexpected value may be set in the high-order timer on this occasion. real time port control while the real time port function is valid, data for the real time port are output from ports p5 2 and p5 3 each time the timer x underflows. (however, if the real time port control bit is changed from 0 to 1 after set of the real time port data, data are output independent of the timer x operation.) if the data for the real time port is changed while the real time port function is valid, the changed data are output at the next underflow of timer x. before using this function, set the p5 2 /rtp 0 , p5 3 /rtp 1 pins to output mode (set 1 to bits 2, 3 of port p5 direction register). note on cntr 0 interrupt active edge selection cntr 0 interrupt active edge depends on the cntr 0 active edge switch bit.
single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 30 timer y timer y is a 16-bit timer and is equipped with the timer latch. the division ratio of timer y is given by 1/(n+1), where n is the value in the timer latch. timer y is a down-counter. when the contents of timer y reach 0000 16 , an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. when the timer underflows, the timer y interrupt request bit is set to 1 . timer y can be selected in one of four modes by the timer y mode register. (1) timer mode the timer counts f(x in )/16 (or f(x cin )/16 in low-speed mode). (2) period measurement mode cntr 1 interrupt request is generated at rising or falling edge of cntr 1 pin input signal. simultaneously, the value in timer y latch is reloaded in timer y and timer y continues counting down. except for this, the operation in period measurement mode is the same as in timer mode. the timer value just before the reloading at rising or falling of cntr 1 pin input signal is retained until the next valid edge is input. the rising or falling timing of cntr 1 pin input signal can be discriminated by cntr 1 interrupt. when using a timer in this mode, set the p5 5 /cntr 1 pin to input mode (set 0 to bit 5 of port p5 direction register). (3) event counter mode the timer counts signals input through the cntr 1 pin. except for this, the operation in event counter mode is the same as in timer mode. when using a timer in this mode, set the p5 5 /cntr 1 pin to input mode (set 0 to bit 5 of port p5 direction register). (4) pulse width hl continuously measure- ment mode cntr 1 interrupt request is generated at both rising and falling edges of cntr 1 pin input signal. except for this, the operation in pulse width hl continuously measurement mode is the same as in period measurement mode. when using a timer in this mode, set the p5 5 /cntr 1 pin to input mode (set 0 to bit 5 of port p5 direction register). note on cntr 1 interrupt active edge selection cntr 1 interrupt active edge depends on the value of the cntr 1 active edge switch bit. however, in pulse width hl continuously measurement mode, cntr 1 interrupt request is generated at both rising and falling edges of cntr 1 pin input signal regardless of the value of cntr 1 active edge switch bit. fig. 26 structure of timer y mode register t i m e r y m o d e r e g i s t e r ( t y m : a d d r e s s 0 0 2 8 1 6 ) b 7 b 0 n o t u s e d ( 0 a t r e a d i n g ) t i m e r y o p e r a t i n g m o d e b i t s b 5b 4 00 : t i m e r m o d e 01 : p e r i o d m e a s u r e m e n t m o d e 10 : e v e n t c o u n t e r m o d e 11 : p u l s e w i d t h h l c o n t i n u o u s l y m e a s u r e m e n t m o d e c n t r 1 a c t i v e e d g e s w i t c h b i t 0 : c o u n t a t r i s i n g e d g e i n e v e n t c o u n t e r m o d e m e a s u r e t h e f a l l i n g e d g e t o f a l l i n g e d g e p e r i o d i n p e r i o d m e a s u r e m e n t m o d e f a l l i n g e d g e a c t i v e f o r c n t r 1 i n t e r r u p t 1 : c o u n t a t f a l l i n g e d g e i n e v e n t c o u n t e r m o d e m e a s u r e t h e r i s i n g e d g e p e r i o d i n p e r i o d m e a s u r e m e n t m o d e r i s i n g e d g e a c t i v e f o r c n t r 1 i n t e r r u p t t i m e r y s t o p c o n t r o l b i t 0 : c o u n t s t a r t 1 : c o u n t s t o p
single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 31 timer 1, timer 2, timer 3 timer 1, timer 2, and timer 3 are 8-bit timers and is equipped with the timer latch. the count source for each timer can be selected by the timer 123 mode register. the division ratio of each timer is given by 1/(n+1), where n is the value in the timer latch. all timers are down-counters. when the contents of the timer reach 00 16 , an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. when the timer underflows, the interrupt request bit corresponding to that timer is set to 1 . when a value is written to the timer 1 register and the timer 3 reg- ister, a value is simultaneously set as the timer latch and the timer. when the timer 1 register, the timer 2 register, or the timer 3 regis- ter is read, the count value of the timer can be read. timer 2 write control which write can be selected by the timer 2 write control bit (bit 2) of the timer 123 mode register (address 0029 16 ), writing data to both the latch and the timer at the same time or writing data only to the latch. when the operation writing data only to the latch is selected, the value is set to the timer 2 latch by writing data to the timer 2 register and the timer 2 is updated at next underflow. after reset, the operation writing data to both the latch and the timer at the same time is selected, and the value is set to both the timer 2 latch and the timer 2 at the same time by writing data to the timer 2 register. if the value is written in latch only, a value is simultaneously set to the timer 2 and the timer 2 latch when the writing in the high- order register and the underflow of timer 2 are performed at the same timing. timer 2 output control when the timer 2 (t out ) output is enabled by the t out / output enable bit and the t out / output selection bit, an inversion signal from the t out pin is output each time timer 2 underflows. in this case, set the p4 3 / /t out pin to output mode (set 1 to bit 3 of port p4 direction register). note on timer 1 to timer 3 when the count source of timers 1 to 3 is changed, the timer counting value may become arbitrary value because a thin pulse is generated in count input of timer. if timer 1 output is selected as the count source of timer 2 or timer 3, when timer 1 is written, the counting value of timer 2 or timer 3 may become undefined value because a thin pulse is generated in timer 1 output. therefore, set the value of timer in the order of timer 1, timer 2 and timer 3 after the count source selection of timer 1 to 3. fig. 27 structure of timer 123 mode register t o u t o u t p u t a c t i v e e d g e s w i t c h b i t 0 : s t a r t a t h o u t p u t 1 : s t a r t a t l o u t p u t t o u t / o u t p u t e n a b l e l b i t 0 : t o u t / o u t p u t d i s a b l e d 1 : t o u t / o u t p u t e n a b l e d t i m e r 2 w r i t e c o n t r o l b i t 0 : w r i t e d a t a i n l a t c h a n d c o u n t e r 1 : w r i t e d a t a i n l a t c h o n l y t i m e r 2 c o u n t s o u r c e s e l e c t i o n b i t 0 : t i m e r 1 o u t p u t s i g n a l 1 : f ( x i n ) / 1 6 ( o r f ( x c i n ) / 1 6 i n l o w - s p e e d m o d e ) t i m e r 3 c o u n t s o u r c e s e l e c t i o n b i t 0 : t i m e r 1 o u t p u t s i g n a l 1 : f ( x i n ) / 1 6 ( o r f ( x c i n ) / 1 6 i n l o w - s p e e d m o d e ) t i m e r 1 c o u n t s o u r c e s e l e c t i o n b i t 0 : f ( x i n ) / 1 6 ( o r f ( x c i n ) / 1 6 i n l o w - s p e e d m o d e ) 1 : f ( x c i n ) n o t u s e d ( 0 a t r e a d i n g ) ti mer 123 mo d e reg i ster (t123m :address 0029 16 ) n ote: s ystem c l oc k i s f(x cin ) /2 i n t h e l ow-spee d mo d e. b 7 b 0

(1) clock synchronous serial i/o mode clock synchronous serial i/o mode is selected by setting the se- rial i/o1 mode selection bit of the serial i/o1 control register to 1 . for clock synchronous serial i/o mode, the transmitter and the re- ceiver must use the same clock as an operation clock. when an internal clock is selected as an operation clock, transmit or receive is started by a write signal to the transmit buffer regis- ter. when an external clock is selected as an operation clock, serial i/ o1 becomes the state where transmit or receive can be performed by a write signal to the transmit buffer register. transmit and re- ceive are started by input of an external clock. fig. 28 block diagram of clock synchronous serial i/o1 fig. 29 operation of clock synchronous serial i/o1 function p 4 6 / s c l k 1 p 4 7 / s r d y 1 p 4 4 / r x d p 4 5 / t x d x i n 1 / 4 1/4 f / f serial i/o1 status register serial i/o1 control register r e c e i v e b u f f e r r e g i s t e r a d d r e s s 0 0 1 8 1 6 receive shift register r ece i ve b u ff er f u ll fl ag (rbf) r e c e i v e i n t e r r u p t r e q u e s t receive clock control circuit s h i f t c l o c k s er i a l i / o 1 sync h ronous clock selection bit frequency division ratio 1/(n+1) baud rate generator a d d r e s s 0 0 1 c 1 6 brg count source se l ect i on bi t f a l l i n g - e d g e d e t e c t o r d ata b us add ress 0018 16 s h i f t c l o c k t ransm i t s hif t reg i ster s hif t comp l et i on fl ag (tsc) t ransm i t b u ff er empty fl ag (tbe) t r a n s m i t i n t e r r u p t r e q u e s t t ransm i t i nterrupt source se l ect i on bi t add ress 0019 16 d ata b us a d d r e s s 0 0 1 a 1 6 t r a n s m i t b u f f e r r e g i s t e r t r a n s m i t s h i f t r e g i s t e r t r a n s m i t cl o c k c o n t r o l c i r c u i t r ece i ve ena bl e s i gna l s rdy1 d 7 d 0 d 1 d 2 d 3 d 4 d 5 d 6 rbf = 1 tsc = 1 tbe = 0 tbe = 1 tsc = 0 t r a n s m i t a n d r e c e i v e s h i f t c l o c k ( 1 / 2 t o 1 / 2 0 4 8 o f t h e i n t e r n a l c l o c k , o r a n e x t e r n a l c l o c k ) s e r i a l o u t p u t t x d s e r i a l i n p u t r x d w r i t e s i g n a l t o r e c e i v e / t r a n s m i t b u f f e r r e g i s t e r ( a d d r e s s 0 0 1 8 1 6 ) o v e r r u n e r r o r ( o e ) d e t e c t i o n n o t e s 1 : a f t e r d a t a t r a n s f e r r i n g , t h e t x d p i n k e e p s d 7 o u t p u t v a l u e . 2 : i f d a t a i s w r i t t e n t o t h e t r a n s m i t b u f f e r r e g i s t e r w h e n t s c = 0 , t h e t r a n s m i t c l o c k i s g e n e r a t e d c o n t i n u o u s l y a n d s e r i a l d a t a c a n b e o u t p u t c o n t i n u o u s l y f r o m t h e t x d p i n . 3 : s e l e c t t h e s e r i a l i / o 1 t r a n s m i t i n t e r r u p t r e q u e s t f a c t o r b e t w e e n w h e n t h e t r a n s m i t b u f f e r r e g i s t e r h a s e m p t i e d ( t b e = 1 ) o r a f t e r t h e t r a n s m i t s h i f t o p e r a t i o n h a s e n d e d ( t s c = 1 ) , b y s e t t i n g t h e t r a n s m i t i n t e r r u p t s o u r c e s e l e c t i o n b i t ( t i c ) o f t h e s e r i a l i / o 1 c o n t r o l r e g i s t e r . 4 : t h e s e r i a l i / o 1 r e c e i v e i n t e r r u p t r e q u e s t o c c u r s w h e n t h e r e c e i v e b u f f e r f u l l f l a g ( r b f ) b e c o m e s 1 . d 7 d 0 d 1 d 2 d 3 d 4 d 5 d 6 ( n o t e 1 ) (n ote 3) (n ote 2) (n ote 3) (n ote 4 )

[a-d control register (adcon)] 0034 16 the a-d control register controls the a-d conversion process. bits 0 to 2 of this register select specific analog input pins. bit 3 indi- cates the completion of an a-d conversion. the value of this bit re- mains at 0 during an a-d conversion, then it is set to 1 when the a-d conversion is completed. writing 0 to this bit starts the a-d conversion. bit 4 is the v ref input switch bit which controls connection of the resistor ladder and the reference voltage input pin (v ref ). the resistor ladder is always connected to v ref when bit 4 is set to 1 . when bit 4 is set to 0 , the resistor ladder is cut off from v ref except for a-d conversion performed. when bit 5, which is the ad external trigger valid bit, is set to 1 , a-d conversion starts also by a falling edge of an adt input. when using an a-d external trigger, set the p5 7 /adt pin to input mode (set 0 to bit 7 of port p5 direc- tion register). comparison voltage generator the comparison voltage generator divides the voltage between av ss and v ref by 256 (when 8-bit a-d mode) or 1024 (when 10- bit a-d mode), and outputs the divided voltages. channel selector the channel selector selects one of the input ports p6 7 /an 7 p6 0 /an 0 . comparator and control circuit the comparator and control circuit compare an analog input volt- age with the comparison voltage and store the result in the a-d conversion register. when an a-d conversion is completed, the control circuit sets the ad conversion completion bit and the ad converter interrupt request bit to 1 . note that because the comparator consists of a capacitor coupling, set f(x in ) to 500 khz or more during an a-d conversion. use the clock divided from the main clock f(x in ) as the system clock . fig. 40 structure of a-d converter-related registers a - d c o n t r o l r e g i s t e r ( a d c o n : a d d r e s s 0 0 3 4 1 6 ) ad convers i on comp l et i on bi t 0 : conversion in progress 1 : conversion completed a na l og i nput p i n se l ect i on bi ts b2b1b0 0 0 0 : p6 0 /an 0 0 0 1 : p6 1 /an 1 0 1 0 : p6 2 /an 2 0 1 1 : p6 3 /an 3 1 0 0 : p6 4 /an 4 1 0 1 : p6 5 /an 5 1 1 0 : p6 6 /an 6 1 1 1 : p6 7 /an 7 v r e f i n p u t s w i t c h b i t 0 : a u t o 1 : o n ad externa l tr i gger va lid bi t 0 : a-d external trigger invalid 1 : a-d external trigger valid b 7 b 0 i nterrupt source se l ect i on bi t 0 : interrupt request at a-d conversion completed 1 : interrupt request at adt input falling n ot use d ( 0 at rea di ng ) a - d c o n v e r s i o n l o w - o r d e r r e g i s t e r ( a d l : a d d r e s s 0 0 1 4 1 6 ) c onvers i on mo d e se l ect i on bi t 0 : 10-bit a-d mode 1 : 8-bit a-d mode not used ( 0 at reading) for 10-bit a-d mode a-d conversion result for 8-bit a-d mode not used (undefined at reading) b 7 b 0

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 50 watchdog timer the watchdog timer gives a mean of returning to the reset status when a program cannot run on a normal loop (for example, be- cause of a software runaway). the watchdog timer consists of an 8-bit watchdog timer l and a 6- bit watchdog timer h. at reset or writing to the watchdog timer control register (address 0037 16 ), the watchdog timer is set to 3fff 16 . when any data is not written to the watchdog timer con- trol register (address 0037 16 ) after reset, the watchdog timer is stopped. the watchdog timer starts to count down from 3fff 16 by writing to the watchdog timer control register and an internal re- set occurs at an underflow. accordingly, when using the watchdog timer function, write the watchdog timer control register before an underflow. the watchdog timer does not function when writing to the watchdog timer control register has not been done after reset. when not using the watchdog timer, do not write to it. when the watchdog timer control register is read, the following values are read: value of high-order 6-bit counter value of stp instruction disable bit value of count source selection bit. when the stp instruction disable bit is 0 , the stp instruction is enabled. the stp instruction is disabled when this bit is set to 1 . if the stp instruction which is disabled is executed, it is processed as an undefined instruction, so that a reset occurs internally. this bit can be set to 1 but cannot be set to 0 by program. this bit is 0 after reset. when the watchdog timer h count source selection bit is 0 , the detection time is set to 8.19 s at f(x cin ) = 32 khz and 32.768 ms at f(x in ) = 8 mhz. when the watchdog timer h count source selection bit is 0 , the detection time is set to 32 ms at f(x cin ) = 32 khz and 128 s at f(x in ) = 8 mhz. there is no difference in the detection time be- tween the middle-speed mode and the high-speed mode. fig. 52 block diagram of watchdog timer fig. 53 structure of watchdog timer control register fig. 54 timing of reset output x in data bus x cin 1 0 internal system clock selection bit (note) 0 1 1/16 watchdog timer h count source selection bit reset circuit undefined instruction reset 3f 16 is set when watchdog timer is written to. internal reset reset reset release time wait ff 16 is set when watchdog timer is written to. stp instruction stp instruction disable bit watchdog timer h (6) watchdog timer l (8) note: this is the bit 7 of cpu mode register and is used to switch the middle-/high-speed mode and low-speed mode. b 7 b 0 w a t c h d o g t i m e r r e g i s t e r ( w d t c o n : a d d r e s s 0 0 3 7 1 6 ) s t p i n s t r u c t i o n d i s a b l e b i t 0 : s t p i n s t r u c t i o n e n a b l e d 1 : s t p i n s t r u c t i o n d i s a b l e d w a t c h d o g t i m e r h c o u n t s o u r c e s e l e c i o n b i t 0 : w a t c h d o g t i m e r l u n d e r f l o w 1 : f ( x i n ) / 1 6 o r f ( x c i n ) / 1 6 watchdog timer h (for read-out of high-order 6 bit) 3fff 16 is set to the watchdog timer by writing values to this address. i n t e r n a l r e s e t s i g n a l w a t c h d o g t i m e r d e t e c t i o n approx. 1 ms (f(x in ) = 8 mh z ) f ( x i n )

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 54 fig. 59 oscillator circuit fig. 60 external clock input circuit clock generating circuit the 7560 group has two built-in oscillation circuits: main clock x in -x out oscillation circuit and sub-clock x cin -x cout oscillation circuit. an oscillation circuit can be formed by connecting an oscil- lator between x in and x out (x cin and x cout ). use the circuit constants in accordance with the oscillator manufacturer s recom- mended values. no external resistor is needed between x in and x out since a feed-back resistor exists on-chip. however, an exter- nal feed-back resistor is needed between x cin and x cout since a resistor does not exist between them. to supply a clock signal externally, input it to the x in pin and make the x out pin open. the sub-clock oscillation circuit cannot directly input clocks that are externally generated. accordingly, be sure to cause an external oscillator to oscillate. immediately after poweron, only the x in oscillation circuit starts oscillating, and x cin and x cout pins go to high-impedance state. frequency control (1) middle-speed mode the clock input to the x in pin is divided by 8 and it is used as the system clock . after reset, this mode is selected. (2) high-speed mode the clock input to the x in pin is divided by 2 and it is used as the system clock . (3) low-speed mode the clock input to the x cin pin is divided by 2 and it is used as the system clock . a low-power consumption operation can be realized by stopping the main clock in this mode. to stop the main clock, set the main clock stop bit of the cpu mode register to 1 . when the main clock is restarted, after setting the main clock stop bit to 0 , set enough time for oscillation to stabilize by pro- gram. note: if you switch the mode between middle/high-speed and low- speed, stabilize both x in and x cin oscillations. the suffi- cient time is required for the sub clock to stabilize, espe- cially immediately after poweron and at returning from stop mode. when switching the mode between middle/high- speed and low-speed, set the frequency in the condition that f(x in ) > 3 f(x cin ). oscillation control (1) stop mode if the stp instruction is executed, the system clock stops at an h level, and main and sub clock oscillators stop. in this time, values set previously to timer 1 latch and timer 2 latch are loaded automatically to timer 1 and timer 2. before the stp instruction, set the values to generate the wait time required for oscillation stabilization to timer 1 latch and timer 2 latch (low-order 8 bits are set to timer 1, high-order 8 bits are set to timer 2). either f(x in ) or f(x cin ) divided by 16 is input to timer 1 as count source, and the output of timer 1 is connected to timer 2. the bits of the timer 123 mode register except bit 4 are set to 0 . set the timer 1 and timer 2 interrupt enable bits to 0 before ex- ecuting the stp instruction. oscillation restarts at reset or when an external interrupt is re- ceived, but the system clock is not supplied to the cpu until timer 2 underflows. this allows time for the clock circuit oscillation to stabilize when a ceramic resonator is used. (2) wait mode if the wit instruction is executed, only the system clock stops at an h state. the states of main clock and sub clock are the same as the state before the executing the wit instruction, and oscilla- tion does not stop. since supply of internal clock is started im- mediately after the interrupt is received, the instruction can be ex- ecuted immediately. x c i n c i n c o u t c c i n c c o u t r f r d x c o u t x i n x o u t x i n x o u t e x t e r n a l o s c i l l a t i o n c i r c u i t o p e n v cc v ss c c i n c c o u t r f r d x c i n x c o u t

single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 57 notes on programming processor status register the contents of the processor status register (ps) after a reset are undefined, except for the interrupt disable flag (i) which is 1 . af- ter a reset, initialize flags (t flag, d flag, etc.) which affect program execution. interrupt when the contents of an interrupt request bits are changed by the program, execute a bbc or bbs instruction after at least one in- struction. this is for preventing executing a bbc or bbs instruction to the contents before change. decimal calculations to calculate in decimal notation, set the decimal mode flag (d) to 1 , then execute an adc or sbc instruction. after executing an adc or sbc instruction, execute at least one instruction before executing a sec, clc, or cld instruction. in decimal mode, the values of the negative (n), overflow (v), and zero (z) flags are invalid. multiplication and division instructions the index mode (t) and the decimal mode (d) flags do not affect the mul and div instruction. the execution of these instructions does not change the contents of the processor status register. ports use instructions such as ldm and sta, etc., to set the port direc- tion registers. the contents of the port direction registers cannot be read. the following cannot be used: lda instruction the memory operation instruction when the t flag is 1 the bit-test instruction (bbc or bbs, etc.) the read-modify-write instruction (calculation instruction such as ror etc., bit manipulation instruction such as clb or seb etc.) the addressing mode which uses the value of a direction regis- ter as an index serial i/o in clock synchronous serial i/o, if the receive side is using an ex- ternal clock and it is to output the s rdy signal, set the transmit en- able bit, the receive enable bit, and the s rdy output enable bit to 1 . the txd pin of serial i/o1 retains the level then after transmission is completed. in serial i/o2 selecting an internal clock, the s out2 pin goes to high impedance state after transmission is completed. in serial i/o2 selecting an external clock, the s out2 pin retains the level then after transmission is completed. a-d converter the input to the comparator is combined by internal capacitors. therefore, since conversion accuracy may be worse by losing of an electric charge when the conversion speed is not enough, make sure that f(x in ) is at least 500 khz during an a-d conver- sion. the normal operation of a-d conversion cannot be guaranteed when performing the next operation: when writing to cpu mode register during a-d conversion op- eration when writing to a-d control register during a-d conversion op- eration when executing stp instruction or wit instruction during a-d conversion operation instruction execution time the instruction execution time is obtained by multiplying the fre- quency of the system clock by the number of cycles needed to execute an instruction. the number of cycles required to execute an instruction is shown in the list of machine instructions. the frequency of the system clock depends on the main clock division ratio selection bit and the system clock selection bit.
single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 58 notes on use countermeasures against noise (1) shortest wiring length ? wiring for reset pin make the length of wiring which is connected to the reset pin as short as possible. especially, connect a capacitor across the reset pin and the v ss pin with the shortest possible wiring (within 20 mm). reason the width of a pulse input into the reset pin is determined by the timing necessary conditions. if noise having a shorter pulse width than the standard is input to the reset pin, the reset is released before the internal state of the microcomputer is com- pletely initialized. this may cause a program runaway. fig. 64 wiring for clock i/o pins (2) connection of bypass capacitor across v ss line and v cc line in order to stabilize the system operation and avoid the latch-up, connect an approximately 0.1 f bypass capacitor across the v ss line and the v cc line as follows: connect a bypass capacitor across the v ss pin and the v cc pin at equal length. connect a bypass capacitor across the v ss pin and the v cc pin with the shortest possible wiring. use lines with a larger diameter than other signal lines for v ss line and v cc line. connect the power source wiring via a bypass capacitor to the v ss pin and the v cc pin. fig. 63 wiring for the reset pin ? wiring for clock input/output pins make the length of wiring which is connected to clock i/o pins as short as possible. make the length of wiring (within 20 mm) across the grounding lead of a capacitor which is connected to an oscillator and the v ss pin of a microcomputer as short as possible. separate the v ss pattern only for oscillation from other v ss patterns. reason if noise enters clock i/o pins, clock waveforms may be de- formed. this may cause a program failure or program runaway. also, if a potential difference is caused by the noise between the v ss level of a microcomputer and the v ss level of an oscil- lator, the correct clock will not be input in the microcomputer. fig. 65 bypass capacitor across the v ss line and the v cc line reset reset circuit noise v ss v ss reset circuit v ss reset v ss n.g. o.k. noise x in x out v ss x in x out v ss n.g. o.k. v ss v cc aa aa aa aa aa aa v ss v cc aa aa aa aa aa aa aa aa aa n.g. o.k.
single-chip 8-bit cmos microcomputer mitsubishi microcomputers 7560 group 59 (3) oscillator concerns in order to obtain the stabilized operation clock on the user system and its condition, contact the oscillator manufacturer and select the oscillator and oscillation circuit constants. be careful espe- cially when range of voltage or/and temperature is wide. also, take care to prevent an oscillator that generates clocks for a microcomputer operation from being affected by other signals. ? keeping oscillator away from large current signal lines install a microcomputer (and especially an oscillator) as far as possible from signal lines where a current larger than the toler- ance of current value flows. reason in the system using a microcomputer, there are signal lines for controlling motors, leds, and thermal heads or others. when a large current flows through those signal lines, strong noise oc- curs because of mutual inductance. ? installing oscillator away from signal lines where potential levels change frequently install an oscillator and a connecting pattern of an oscillator away from signal lines where potential levels change frequently. also, do not cross such signal lines over the clock lines or the signal lines which are sensitive to noise. reason signal lines where potential levels change frequently (such as the cntr pin signal line) may affect other lines at signal rising edge or falling edge. if such lines cross over a clock line, clock waveforms may be deformed, which causes a microcomputer failure or a program runaway. ? keeping oscillator away from large current signal lines ? installing oscillator away from signal lines where potential levels change frequently fig. 67 wiring for the v pp pin of one time prom fig. 66 wiring for a large current signal line/ wiring of signal lines where potential levels change frequently (4) analog input the analog input pin is connected to the capacitor of a compara- tor. accordingly, sufficient accuracy may not be obtained by the charge/discharge current at the time of a-d conversion when the analog signal source of high-impedance is connected to an analog input pin. in order to obtain the a-d conversion result stabilized more, please lower the impedance of an analog signal source, or add the smoothing capacitor to an analog input pin. (5) difference of memory type and size when mask rom and prom version and memory size differ in one group, actual values such as an electrical characteristics, a-d conversion accuracy, and the amount of proof of noise incorrect operation may differ from the ideal values. when these products are used switching, perform system evalua- tion for each product of every after confirming product specification. (6) wiring to v pp pin of one time prom version and eprom version connect an approximately 5 k ? resistor to the v pp pin the shortest possible in series. note: even when a circuit which included an approximately 5 k ? resistor is used in the mask rom version, the microcom- puter operates correctly. reason the v pp pin of the prom version is the power source input pin for the built-in prom. when programming in the built-in prom, the impedance of the v pp pin is low to allow the electric current for writing flow into the built-in prom. because of this, noise can en- ter easily. if noise enters the v pp pin, abnormal instruction codes or data are read from the built-in prom, which may cause a pro- gram runaway. x i n x o u t v s s m i c r o c o m p u t e r mutual inductance l a r g e c u r r e n t g n d m x i n x o u t v s s c n t r d o n o t c r o s s n.g. p 7 0 / v p p v ss a b o u t 5 k ? s o u r c e s i g n a l
