PIN FUNCTIONS 2.1 Normal Operation Mode (1/2) Pin No. Symbol Function Output Format At Reset 27 (28) P0D0 These pins constitute a 4-bit I/O port which can be set in the input N-ch Low-level 28 (29) P0D1 or output mode in 4-bit units (group I/O). open-drain output 1 (1) P0D2 In the input mode, these pins serve as CMOS input pins with a 2 (2) P0D3 pull-up resistor, and can be used as key return input lines of a key matrix. The standby status must be released when at least one of the input lines goes low. In the output mode, these pins are used as N-ch open-drain output pins and can be used as the output lines of a key matrix. 3 (3) INT External interrupt request signal. This signal releases the standby – Input status if an external interrupt request signal is input to it when the INT pin interrupt enable flag (IP) is set. 4 (4) P0E0 These pins constitute a 4-bit I/O port that can be set in the input or CMOS Input 5 (5) P0E1 output mode in 1-bit units. push-pull 6 (6) P0E2 In the output mode, this port functions as a high current CMOS 7 (7) P0E3 output port. In the input mode, function as CMOS input and can be specified to connect pull-up resistor by program. 8 (8) REM Outputs transfer signal for infrared remote controller. CMOS Low-level Active-high output. push-pull output 9 (9) VDD Power supply – – 10 (10) XOUT Connects ceramic resonator for system clock oscillation – (Oscillation 11 (11) XIN stops) 12 (12) GND Ground – – 13 (13) RESET Turns ON pull down resistor if POC or watchdog timer overflows – Input and if the stack pointer overflows or underflows, and resets the system. Usually, the pull-down resistor is ON. 14 (14) P1A0 µPD17P136M1, This pin is 1-bit output port (N-ch open-drain N-ch High- µPD17P136M3 output) and can be used as the output lines of open-drain impedance a key matrix. output µPD17P136M2, This pin is 1-bit input port (CMOS input). – Input µPD17P136M4 However, it cannot release the STOP mode. 15 (16) P0A0 These pins are CMOS input pins with a 4-bit pull-up resistor. – Input 16 (17) P0A1 They can be used as the key return input lines of a key matrix. 17 (18) P0A2 If any one of these pins goes low, the standby status is released. 18 (19) P0A3 19 (20) P0B0 These pins constitute a 4-bit I/O port that can be set in the input or N-ch Input 20 (21) P0B1 output mode in 1-bit units. open-drain 21 (22) P0B2 In the input mode, these pins are CMOS input pins with a pull-up 22 (23) P0B3 resistor, and can be used as the key return input lines of a key matrix. The standby status is released when at least one of these pins goes low. In the output mode, they serve as N-ch open-drain output pins and can be used as the output lines of a key matrix. Remark The number in parenthesis in the Pin No. column indicates the pin numbers of the 30-pin plastic SSOP. |
