DESCRIPTION

Power supply input pins for digital circuit.

P0.2: Input only pin (Schmitt trigger) if disable external reset function.

P0.2 without build-in pull-up resister

P0.2 is input only pin without pull-up resistor under P0.2 mode. Add the 100 ohm

external resistor on P0.2, when it is set to be input pin.

RST: System reset input pin. Schmitt trigger structure, low active, normal stay to “high”.

VPP: OTP programming pin.

Oscillator input pin while external oscillator enable (crystal and RC).

XOUT: Oscillator output pin while external crystal enable.

Fcpu: Signal output pin while external RC mode enable.

Port 0.0 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

INT0 trigger pin (Schmitt trigger).

Port 0.1 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

INT1 trigger pin (Schmitt trigger).

TC1 event counter clock input pin.

Port 1.0, P1.1 bi-direction pin and open-drain pin. Schmitt trigger structure as input

mode.

Built-in pull-up resisters.

Port 1.2~P1.7 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

Bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

Port 5 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

Port 5.3 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

TC1 ÷ 2 signal output pin for buzzer or PWM1 output pin.
