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
Pins not actually part of Port Module, but included here for complete listing of available I/O ports. See separate section for
