DESCRIPTION

P Power supply input pins for digital and analog circuit.

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

to “high”.

I, P VPP: OTP 12.3V power input pin in programming mode.

P1.1: Input only pin with Schmitt trigger structure and no pull-up resistor. Level change

wake-up.

P0.0: Bi-direction pin. Schmitt trigger structure as input mode. Built-in pull-up resisters.

I/O Level change wake-up.

INT0: External interrupt 0 input pin.

I/O

P1.0: Bi-direction pin. Schmitt trigger structure as input mode. Built-in pull-up resisters.

Level change wake-up. Programmable open-drain structure.

XOUT: Oscillator output pin while external crystal enable.

I/O P1.2: Bi-direction pin. Schmitt trigger structure as input mode. Built-in pull-up resisters.
