C8051F320 has dedicated pins for power and the USB connection, plus 25 general purpose I/O pins that
connect to the various internal resources through a programmable crossbar. Hardware connections on
CRD5376 limit how the blocks can operate, so the port mapping of microcontroller resources is detailed
below.
