1.4 PIN DESCRIPTIONS

PIN NAME

TYPE

DESCRIPTION

VDD, VSS

Power supply input pins for digital circuit.

P1.5/RST/VPP

I, P

P1.5: Input only pin (Schmitt trigger) if disable external reset function.

P1.5 without build-in pull-up resister.

P1.5 is input only pin without pull-up resistor under P1.5 mode. Add the 100

ohm external resistor on P1.5, when it is set to be input pin.

Built-in wakeup function.

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

“high”.

VPP: OTP programming pin.

P1.6/XIN

I/O

Port 1.6 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

Built-in wakeup function.

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

P1.4/XOUT

I/O

Port 1.4 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

Built-in wakeup function.

XOUT: Oscillator output pin while external crystal enable.

P0.0/INT0

I/O

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

Built-in pull-up resisters.

Built-in wakeup function.

INT0 trigger pin (Schmitt trigger).

TC0 event counter clock input pin.

P0.1/INT1

I/O

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

Built-in pull-up resisters.

Built-in wakeup function.

INT1 trigger pin (Schmitt trigger).

P1.0

I/O

Port P1.0 bi-direction pins and open-drain pin. Schmitt trigger structure as input

mode.

Built-in pull-up resisters.

Built-in wakeup function

P1 [3:1], P1.7

I/O

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

Built-in pull-up resisters.

Built-in wakeup function

P5 [7:0]

I/O

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

Built-in pull-up resisters.

P5.4/BZ0/PWM0

I/O

Port 5.4 bi-direction pin. Schmitt trigger structure as input mode.

Built-in pull-up resisters.

TC0 ÷ 2 signal output pin for buzzer or PWM0 output pin.
