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 8.12.1 “Port
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt triggered inputs.
Port 0 also provides various special functions as described below:
