Type Description

P0.0 to P0.5

I/O

Port 0: Port 0 is a 6-bit I/O port with user-configurable outputs. During reset Port 0

latches are configured 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 configuration

selected. Each port pin is configured independently. Refer to Section 9.12.1 “Port

configurations” and Table 13 “DC electrical characteristics” for details.

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:
