32. Pinout and Pin Functions
The device pinout is shown in “Pinout and Block Diagram” on page 4. In addition to general purpose I/O functionality,
each pin can have several alternate functions. This will depend on which peripheral is enabled and connected to the
actual pin. Only one of the pin functions can be used at time.
32.1 Alternate Pin Function Description
