Detailed Description

Common implementations and headers for ATxmega family based micro-controllers.

Basic definitions for the ATxmega common clock module

When ever you want to do something hardware related, that is accessing MCUs registers directly, just include this file. It will then make sure that the MCU specific headers are included.
