28. 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.
