Description

P0: 8-bit input-output port. Each bit can be assigned to input or output.

AD: Outputs the lower 8 bits of program counter during external program memory fetch,

and receives the addressed instruction under the control of PSEN. This pin also

outputs the address and outputs or inputs data during an external data memory

access instruction, under the control of ALE, RD, and WR.

P1: 8-bit input-output port. Each bit can be assigned to input or output.

A: Outputs the upper 8 bits of program counter (PC8–15) during external program

memory fetch. This pin also outputs the upper 8 bits of address during external

data memory access instructions.

P2: 8-bit input-output port. Each bit can be assigned to input or output.

CLKOUT: Output pin for supplying a clock to peripheral circuits.

HOLD: Input pin to request the CPU to enter the hardware power-down state.

HLDA: HOLD ACKNOWLEDGE: the HLDA signal appears in response to the HOLD

signal and indicates that the CPU has entered the power-down state.

TXC: Transmitter clock input/output pin.

RXC: Receiver clock input/output pin.

P3: 8-bit input-output port. Each bit can be assigned to input or output.

TXD: Transmitter data output pin.

RXD: Receiver data input pin.

INT: Interrupt request input pin.

Falling edge trigger or level trigger is selectable.

TM0IO-TM3IO: One of the following signals is output or input.

• Clock at twice the frequency range of the 16-bit timer overflow

• Load trigger signal to the capture register input

• Setting value output

Whether the signal is input or output depends on the mode.

P4: 8-bit input-output port. Each bit can be assigned to input or output.

TM0CK, TM1CK: Clock input pins of timer 0, timer 1.

TRANS: Transition detector.

The input pins which sense the falling edge and set the flag.

PWM: 16-bit pulse-width modulator output pin.

P5: 8-bit input port.

AI: Analog signal input pin for A/D converter.
