Description

PA0~PA7

I/O

Pull-high

Wake-up

Bidirectional 8-bit input/output port. Each bit can be configured as wake-up in-

put by options. Software instructions determine the CMOS output or Schmitt

trigger input with a pull-high resistor (determined by pull-high options).

PB0~PB2

I/O

Pull-high

Bidirectional 3-bit input/output port. Software instructions determine the

CMOS output or Schmitt trigger input with a pull-high resistor (determined by

pull-high options).

Crystal

or RC

OSC1, OSC2 are connected to an RC network or a crystal (determined by

code option) for the internal system clock. In the case of RC operation, OSC2

is the output terminal for 1/4 system clock (NMOS open drain output).
