Pin Description
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 these Port pins are also shared with other function such
as the Analog to Digital Converter, Serial Port 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.
The following tables only include the pins which are directly related to the MCU. The pin descriptions of the additional
peripheral functions are located at the end of the datasheet along with the relevant peripheral function functional de-
scription.
