Description

I Analog input pins to A/D converter

O D/A converter output pins

I/O CMOS I/O ports. Each port has an I/O select direction

register, allowing each pin in the port to be directed for input

or output individually.

Any port set to input can be set to use a pull-up resistor or not

by a program.

P2_0 to P2_7 also function as LED drive ports.
