P0.0 to P0.7

I/O Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type.

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 7.13.1 “Port configurations”

and Table 9 “Static characteristics” for details.

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:
