With the exception of the power pins, all pins on these devices can be referenced by their Port name,
e.g. PA.0, PA.1 etc, which refer to the digital I/O function of the pins. However some of these Port pins
are also shared with other function such as the Analog to Digital Converter, Timer Module pins etc.
The function of each pin is listed in the following table, however the details behind how each pin is
configured is contained in other sections of the datasheet.
