Description
Port 0: Port 0 is a 32-bit I/O port with individual direction
controls for each bit. A total of 31 pins of the Port 0 can be
used as general purpose bidirectional digital I/Os while P0.31
is an output only pin. The operation of port 0 pins depends
upon the pin function selected via the pin connect block.
