Port 0 Data.
Sets the Port latch logic
value or reads the Port pin
logic state in Port cells con-
figured for digital I/O.
These bits select Port 0 pins to be skipped by the Crossbar Decoder. Port pins used
for analog, special functions or GPIO should be skipped by the Crossbar.
0: Corresponding P0.n pin is not skipped by the Crossbar.
1: Corresponding P0.n pin is skipped by the Crossbar.
