3. Module Pinout and Microcontroller Block Diagram

Alternate Port Functions

In addition to the input/output functions on all port pins, most pins have alternate functions. This means that

other modules or peripherals connected to the port can use the port pins for their functions, such as

communication or pulse-width modulation. Section “Pinout and Pin Functions” of XmegaA1 datasheet shows

which modules on peripherals that enables alternate functions on a pin, and what alternate functions that is

available on a pin.
