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 bi-directional
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.
