the low-level output side is held low. 2. in order to prevent malfunction, be sure to input a low level to more than one of pins k i0 to k i3 when reset is released (when reset pin changes from low level to high level, or poc is released due to supply voltage startup). these pins refer to the 8-bit i/o ports. i/o switching can be made in 8-bit units. in input mode, a pull-down resistor is added. in output mode, they can be used as the key scan output of the key matrix. refers to the input port. can also be used as the key return input of the key matrix. in input mode, the availability of the pull-down resistor of the s 0 and s 1 ports can be specified by software in terms in 2-bit units. if input mode is canceled by software, this pin is placed in off mode and enters the high-impedance state. refers to the i/o port. in input mode (s 1 ), this pin can also be used as the key return input of the key matrix. the availability of the pull-down resistor of the s 0 and s 1 ports can be specified by software in 2-bit units. in output mode (led), it becomes the remote control transmission display output (active low). when the remote control carrier is output from the rem output, this pin outputs the low level from the led output synchronously with the rem signal. refers to the infrared remote control transmission output. the output is active high. carrier frequency: f osc , f osc /8, f osc /12, high-level, f osc /2, f osc /16, f osc /24 (usable on software) refers to the power supply. these pins refer to the pins for rc oscillation. refers to the ground. normally, this pin is a system reset input. by inputting a low level, the cpu can be reset. when resetting with the poc circuit (mask option) a low level is output. a pull-up resistor is incorporated. these pins refer to the 4-bit input ports. they can be used as the key return input of the key matrix. the use of the pull-down resistor can be specified by software in 4-bit units. 7 m pd6604 data sheet u11281ej3v0ds00

if the condition specified with the operand is met when the stts instruction has been executed ? when standby mode is canceled. ? when the cancelation condition is met at the point of executing the halt instruction. (in this case, the system is not placed in standby mode.) conversely, the status flag is cleared (to 0) in the following cases: ? if the condition specified with the operand is not met when the stts instruction has been executed. ? when the status flag has been set (to 1), the halt instruction executed, but the cancelation condition is not met at the point of executing the halt instruction. (in this case, the system is not placed in standby mode.) table 2-1. conditions for status flag (f) to be set by stts instruction operand value of stts instruction condition for status flag (f) to be set b 3 b 2 b 1 b 0 0000 high level is input to at least one of k i pins. 0 1 1 high level is input to at least one of k i pins. 1 1 0 high level is input to at least one of k i pins. 1 0 1 the down counter of the timer is 0. 1 either of the combinations [the following condition is added in addition to the above.] of b 2 , b 1 , and b 0 above. high level is input to at least one of s 0 and s 1 pins. 13 m pd6604 data sheet u11281ej3v0ds00 2.9.2 carry flag (cy) the carry flag is set (to 1) in the following cases: ? if the anl instruction or the xrl instruction is executed when bit 3 of the accumulator is 1 and bit 3 of the operand is 1. ? if the rl instruction or the rlz instruction is executed when bit 3 of the accumulator is 1. ? if the inc instruction or the scaf instruction is executed when the value of the accumulator is 0fh. the carry flag is cleared (to 0) in the following cases: ? if the anl instruction or the xrl instruction is executed when at least either bit 3 of the accumulator or bit 3 of the operand is 0. ? if the rl instruction or the rlz instruction is executed when bit 3 of the accumulator is 0. ? if the inc instruction or the scaf instruction is executed when the value of the accumulator is other than 0fh. ? if the orl instruction is executed. ? when data is written to the accumulator by the mov instruction or the in instruction. 14 m pd6604 data sheet u11281ej3v0ds00 3. port registers (px) the k i/o port, the k i port, the special ports (s 0 , s 1 /led), and the control register are treated as port registers. at reset, port register values are shown below. figure 3-1. port register organization port register p0 k i/o7 p 00 at reset ffh k i/o6 k i/o5 k i/o4 k i/o3 k i/o2 k i/o1 k i/o0 p 10 p1 k i3 p 01 fh note k i2 k i1 k i0 s 1 /led s 0 11 p 11 p3 (control register 0) 0 p 03 03h 0dp 9 dp 8 tctl cary mod 1 mod 0 p 13 p4 (control register 1) 0 p 04 26h 0 k i pull-down s 0 /s 1 pull-down 0 s 1 /led mode k i/o mode s 0 mode p 14 note : refers to the value based on the k i pin state. table 3-1. relationship between ports and their read/write port name input mode output mode read write read write k i/o pin state output latch output latch output latch k i pin state s 0 pin state note s 1 /led pin state pin state note when in off mode, 1 is normally read. 15 m pd6604 data sheet u11281ej3v0ds00 3.1 k i/o port (p0) the k i/o port is an 8-bit input/output port for key scan output. input/output mode is set by bit 1 of the p4 register. if a read instruction is executed, the pin state can be read in input mode, whereas the output latch contents can be read in output mode. if the write instruction is executed, data can be written to the output latch regardless of input or output mode. when reset, the port is placed in output mode; and the value of the output latch (p0) becomes 1111 1111b. the k i/o port contains the pull-down resistor, allowing pull-down in input mode only. caution during double pressing of a key, a high-level output and a low-level output may coincide with each other at the k i/o port. to avoid this, the low-level output current of the k i/o port is held low. therefore, be careful when using the k i/o port for purposes other than key scan output. the k i/o port is so designed that, even when connected directly to v dd within the normal supply voltage range (v dd = 1.8 to 3.6 v), no problem may occur. table 3-2. k i/o port (p0) bit b 7 b 6 b 5 b 4 b 3 b 2 b 1 b 0 name k i/o7 k i/o6 k i/o5 k i/o4 k i/o3 k i/o2 k i/o1 k i/o0 b 0 -b 7 : in reading : in input mode, the k i/o pins state is read. in output mode, the k i/o pins output latch contents are read. in writing : data is written to the k i/o pins output latch regardless of input or output mode. 16 m pd6604 data sheet u11281ej3v0ds00 3.2 k i port/special ports (p1) 3.2.1 k i port (p 11 : bits 4-7 of p1) the k i port is to the 4-bit input port for key entry. the pin state can be read. software can be used to set the availability of the pull-down resistor of the k i port in 4-bit units by means of bit 5 of the p4 register. when reset, the pull-down resistor is connected. table 3-3. k i /special port register (p1) bit b 7 b 6 b 5 b 4 b 3 b 2 b 1 b 0 name k i3 k i2 k i1 k i0 s 1 /led s 0 (fixed to 1) b 2 : in input mode, state of the s 0 pin is read (read only). in off mode, this bit is fixed to 1. b 3 : the state of the s 1 /led pin is read regardless of input/output mode (read only). b 4 -b 7 : the state of the k i pin is read (read only). caution in order to prevent malfunction, be sure to input a low level to more than one of pins k i0 to k i3 when reset is released (when reset pin changes from low level to high level, or poc is released due to supply voltage startup). 3.2.2 s 0 port (bit 2 of p1) the s 0 port is the input/off mode port. the pin state can be read by setting this port to input mode with bit 0 of the p4 register. in input mode, software can be used to set the availability of the pull-down resistor of the s 0 and s 1 /led port in 2-bit units by means of bit 4 of the p4 register. if input mode is canceled (thus set to off mode), the pin becomes high-impedance but it also makes that the through current does not flow internally. in off mode, 1 can be read regardless of the pin state. when reset, it is set to off mode, thus becoming high-impedance. 3.2.3 s 1 /led (bit 3 of p1) the s 1 /led port is the input/output port. it uses bit 2 of the p4 register to set input or output mode. the pin state can be read in both input mode and output mode. when in input mode, software can be used to set the availability of the pull-down resistor of the s 0 and s 1 /led ports in 2-bit units by means of bit 4 of the p4 register. when in output mode, the pull-down resistor is automatically disconnected thus becoming the remote transmission display pin (see 4. timer ). when reset, it is placed in output mode, and high level is output. 17 m pd6604 data sheet u11281ej3v0ds00 3.3 control register 0 (p3) control register 0 consists of 8 bits. the contents that can be controlled are as shown below. when reset, the register becomes 0000 0011b. table 3-4. control register 0 (p3) bit b 7 b 6 b 5 b 4 b 3 b 2 b 1 b 0 name dp (data pointer) tctl cary mod 1 mod 0 dp 9 dp 8 set 0 fixed fixed 0 0 1/1 on see table 3-5 . value 1 to 0 to 0 1 1 1/2 off when reset 00000011 b 0 , b 1 : these bits specify the carrier frequency and duty ratio of the rem output. b 2 : this bit specifies the availability of the carrier of the frequency specified by b 0 and b 1 . 0 = on (with carrier);

poc) or the operand of halt instruction. if the standby mode is released, the status flag (f) is set (to 1). even when the halt instruction is executed in the state that the status flag (f) has been set (to 1), the standby mode is not set. if the release condition is not met at this time, the status flag is cleared (to 0). if the release conditio n is met, the status flag remains set (to 1). even in the case when the release condition has been already met at the point that the halt instruction is executed, the standby mode is not set. here, also, the status flag (f) is set (to 1). caution depending on the status of the status flag (f), the halt instruction may not be executed. be careful about this. for example, when setting halt mode after checking the key status with the stts instruction, the system does not enter halt mode as long as the status flag (f) remains set (to 1) thus sometimes performing an unintended operation. in this case, the intended operation can be realized by executing the stts instruction immediately after timer setting to clear (to 0) the status flag. example stts #03h ;to check the k i pin status. mov t, #0xxh ;to set the timer stts #05h ;to clear the status flag (during this time, be sure not to execute an instruction that may set the status flag.) halt #05h ;to set halt mode table 5-2. addresses executed after standby mode released release condition address executed after released reset 0 address release condition shown in table 5-3 the address following the halt instruction 24 m pd6604 data sheet u11281ej3v0ds00 table 5-3. standby mode setup (halt #b 3 b 2 b 1 b 0 b) and release conditions operand value of halt instruction setting mode precondition for setup release condition b 3 b 2 b 1 b 0 0000 stop all k i/o pins are high-level output. high level is input to at least one of k i pins. 0 1 1 stop all k i/o pins are high-level output. high level is input to at least one of k i pins. 1 1 0 stop note 1 the k i/o0 pin is high-level output. high level is input to at least one of k i pins. 1 any of the stop [the following condition is added in addition to the above.] combinations of high level is input to at least one b 2 b 1 b 0 above of s 0 and s 1 pins note 2 . 0/1 1 0 1 halt when the timers down counter is 0 notes 1. when setting halt # 110b, configure a key matrix by using the k i/o0 pin and the k i pin so that an internal reset takes effect at the time of program overrun. 2. at least one of the s 0 and s 1 pins (the pin used for canceling the standby) must be in input mode. (the internal reset does not take effect even when both pins are in output mode.) cautions 1. the internal reset takes effect when the halt instruction is executed with an operand value other than that above or when the precondition has not been satisfied when executing the halt instruction. 2. if stop mode is set when the timers down counter is not 0 (timer operating), the system is placed in stop mode only after all the 10 bits of the timers down counter and the timer output permit flag are cleared to 0. 3. write the nop instruction as the first instruction after stop mode is released. 5.3 standby mode release timing (1) stop mode release timing figure 5-1. stop mode cancelation by release condition wait (36/f osc ) halt mode operating mode stop mode oscillation stopped oscillation operating mode oscillation halt instruction (stop mode) standby release signal clock caution when a release condition is established in the stop mode, the device is released from the stop mode and goes into a wait status. at this time, if the release condition is not held, the device goes into the stop mode again after the wait time has elapsed. therefore, when releasing the stop mode, it is necessary to hold the release condition longer than the wait time. 25 m pd6604 data sheet u11281ej3v0ds00 figure 5-2. stop mode release by reset input wait (60 to 116)/f osc halt mode operating mode stop mode oscillation stopped oscillation operating mode oscillation halt instruction (stop mode) reset clock reset 0 address start (2) halt mode release timing figure 5-3. halt mode release by release condition halt mode operating mode oscillation operating mode halt instruction (halt mode) standby release signal clock figure 5-4. halt mode release by reset input wait (60 to 116)/f osc halt mode operating mode halt mode oscillation stopped oscillation operating mode oscillation halt instruction (halt mode) reset clock reset 0 address start 26 m pd6604 data sheet u11281ej3v0ds00 6. reset pin the system reset takes effect by inputting low level to the reset pin. while the reset pin is at low level, the system clock oscillator is stopped and the osc out pin is fixed to high- impedance, the osc in pin is fixed to the gnd. if the reset pin is raised from low level to high level, it executes the program from the 0 address after counting 60 to 116 of the system clock (f osc ). figure 6-1. reset operation by reset input wait (60 to 116)/f osc halt mode oscillation stopped operating mode or standby mode reset 0 address start operating mode the reset pin outputs low level when the poc circuit (mask option) is in operation. caution when connecting a reset ic to the reset pin, ensure that the ic is of the n-ch open-drain output type. table 6-1. hardware statuses after resetting ?

high reliability is not required. ? clock frequency f osc = 300 to 500 khz ? power supply voltage v dd = 2.2 to 3.6 v ? operating ambient temperature t a = C20 to +70 c cautions 1. the one-time prom product ( m pd66p04b) originally contains the poc circuit. 2. there are cases in which the poc circuit cannot detect a low power supply voltage of less than 1 ms. therefore, if the power supply voltage has become low for a period of less than 1 ms, the poc circuit may malfunction because it does not generate an internal reset signal. 3. if the applied circuit does not satisfy the conditions above, design the applied circuit in such a manner that the reset takes effect without failure within the power supply voltage range by means of an external reset circuit. 4. in order to prevent malfunction, be sure to input a low level to more than one of pins k i0 to k i3 when reset is released (when reset pin changes from low level to high level, or poc is released due to supply voltage startup). remarks 1. it is recommended that the poc circuit be incorporated when applied circuits are infrared remote- control transmitters for consumer appliances. 2. even when a poc circuit is incorporated, the externally entered reset input is valid with the or condition; therefore, the poc circuit and the reset input can be used at the same time. however, if the poc circuit detects a low power supply voltage, the reset pin will be forced to low level; therefore, use an n-ch open drain output or npn open collector output for the external reset circuit. 28 m pd6604 data sheet u11281ej3v0ds00 7.1 functions of poc circuit the poc circuit has the following functions: ? generates an internal reset signal when v dd v poc . ? cancels an internal reset signal when v dd > v poc . here, v dd : power supply voltage, v poc : poc-detected voltage. v dd 0.9 v 0 v internal reset signal reset operating ambient temperature t a = _ 20 to + 70? clock frequency f osc = 300 to 500 khz ? poc-detected voltage v poc = 0.9 to 2.2 v note 3 ? t operating mode - reset note 2 - note 1 3.6 v 2.2 v v pos notes 1. in reality, there is the oscillation stabilization wait time until the circuit is switched to operating mode. the oscillation stabilization wait time is about 60/f osc to about 116/f osc (about 130 to 250 m s; when f osc = 455 khz). 2. for the poc circuit to generate an internal reset signal when the power supply voltage has fallen, it is necessary for the power supply voltage to be kept less than the v poc for the period of 1 ms or more. therefore, in reality, there is the time lag of up to 1 ms until the reset takes effect. 3. the poc-detected voltage (v poc ) varies between 0.9 to 2.2 v; thus, the resetting may be canceled at a power supply voltage smaller than the assured range (v dd = 1.8 to 3.6 v). however, as long as the conditions for operating the poc circuit are met, the actual lowest operating power supply voltage becomes lower than the poc-detected voltage. therefore, there is no malfunction occurring due to the shortage of power supply voltage. 29 m pd6604 data sheet u11281ej3v0ds00 8. system clock oscillator the system clock oscillator consists of rc oscillation circuits (f osc = 300 khz to 1 mhz). figure 8-1. system clock pd6604 osc out osc in gnd m r c the system clock oscillator stops its oscillation when reset or in stop mode. caution when using the system clock oscillator, wire area indicated by the dotted-line in the diagram as follows to reduce the effects of the wiring capacitance, etc. ?

do not extract signals from the oscillation circuit. 30 m pd6604 data sheet u11281ej3v0ds00 remark theoretically, the oscillation frequency of the system clock is determined by the values of c and r. actually, however, it also changes depending on supply voltage v dd and operating ambient temperature t a . moreover, the oscillation frequency of some devices differs from that of the others even when r and c of the same values are connected because of variations in the devices and wiring of the set board. it is therefore difficult to accurately calculate the values of the oscillation frequency and r. however, an approximate value can be obtained by an approximate calculation (such as an expression calculating the value of r from the f osc value) using data measured under fixed conditions. the expression shown below was obtained experimentally. this can be used to calculate the resistor r necessary to obtain the oscillation frequency f osc under the conditions of c = 27 pf, v dd = 3.0 v, and t a = 25 c. r = 26400 C 2.40 [k w ] (where v dd = 3.0 v, and t a = 25 c, and c = 27 pf) f osc [khz] example of f osc vs r characteristics (reference) oscillation frequency f osc [khz] oscillation resistance r [k w ] 1000 300 100 (c = 27 pf, v dd = 3.0 v, and t a = 25 c) 10 20 30 50 70 80 100 31 m pd6604 data sheet u11281ej3v0ds00 9. instruction set 9.1 machine language output by assembler the bit length of the machine language of this product is 10 bits per word. however, the machine language that is output by the assembler is extended to 16 bits per word. as shown in the example below, the expansion is made by inserting 3-bit extended bits (111) in two locations. figure 9-1. an example of assembler output (10 bits extended to 16 bits) <1> in the case of anl a, @r0h 1 1 1010 1 0000 1010 1 0000 111 111 extended bits extended bits = faf0 <2> in the case of ?ut p0, #data8 0 0 0110 1 1000 0110 1 1000 111 111 extended bits extended bits = e6f8 32 m pd6604 data sheet u11281ej3v0ds00 9.2 circuit symbol description a : accumulator asr : address stack register addr : program memory address cy : carry flag data4 : 4-bit immediate data data8 : 8-bit immediate data data10 : 10-bit immediate data f : status flag pc : program counter pn : port register pair (n = 0, 1, 3, 4) p0n : port register (low-order 4 bits) p1n : port register (high-order 4 bits) romn : bit n of the program memorys (n = 0-9) rn : register pair r0n : data memory (general-purpose register; n = 0-f) r1n : data memory (general-purpose register; n = 0-f) sp : stack pointer t : timer register t0 : timer register (low-order 4 bits) t1 : timer register (high-order 4 bits) ( ) : content addressed with 33 m pd6604 data sheet u11281ej3v0ds00 9.3 mnemonic to/from machine language (assembler output) contrast table accumulator operation instructions mnemonic operand instruction code operation instruction instruction 1st word 2nd word 3rd word length cycle anl a, r0n fben (a) ?
