31. Pinout and Pin Functions
The device pinout is shown in “Pinout/Block Diagram” on page 3. 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.
