Pin Description

I/O port with bit-programmable pins.

Configurable to input or push-pull output

mode. Pull-up resistors can be assigned

by software. Pins can also be assigned

individually as alternative function pins.

I/O port with bit-programmable pins.

Configurable to input mode, push-pull

output mode, or n-channel open-drain

output mode. Input mode with pull-up

resistors can be assigned by software.

The port 2 pins have high current drive

capability. Pins can also be assigned

individually as alternative function pins.
