Description
Port 0:
Port 0 is a 32-bit I/O port with individual direction controls for each bit. Total of
31 pins of the Port 0 can be used as a general purpose bidirectional digital I/Os while
P0.31 is output only pin. The operation of port 0 pins depends upon the pin function
selected via the pin connect block.
Pin P0.24 is not available.
