Memory Map/Register Definition  
Refer to Chapter 14, “Signal Descriptions” for more detailed descriptions of these pins. The
function of the pins (primary function, GPIO, etc.) is determined by the various ports
registers and the mode of operation. Refer to Table 14-1 for detailed descriptions of pin
functions.

The primary functionality of a pin is not necessarily the default function of the pin after reset. Pins that have muxed GPIO functionality 
will default to GPIO inputs.

Function available in master mode only
3
Pins not actually part of Port Module, but included here for complete listing of available I/O ports. See separate section for description 
of this port.
