Type Description
P0.0 to P0.7
I/O
Port 0: Port 0 is an 8-bit I/O port with a user-congurable output type. During reset
Port 0 latches are congured in the input only mode with the internal pull-up disabled.
The operation of Port 0 pins as inputs and outputs depends upon the port conguration
selected. Each port pin is congured independently. Refer to Section 7.13.1 “Port
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt trigger inputs.
Port 0 also provides various special functions as described below:
P0.0/CMP2/

I/O
P0.0 — Port 0 bit 0.
O
CMP2 — Comparator 2 output.
I
KBI0 — Keyboard input 0.
