Atmel8210GAVR XMEGA D12/20141. About the Manual
This document contains in-depth documentation of all peripherals and modules available for the AVR XMEGA D
microcontroller family. All features are documented on a functional level and described in a general sense. All peripherals
and modules described in this manual may not be present in all AVR XMEGA D devices.
For all device-specific information such as characterization data, memory sizes, modules, peripherals available, and their
absolute memory addresses, refer to the device datasheets. When several instances of a peripheral exists in one device,
each instance will have a unique name. For example each port module (PORT) have unique name, such as PORTA,
PORTB, etc. Register and bit names are unique within one module instance.
For more details on applied use and code examples for peripherals and modules, refer to the Atmel AVR XMEGA
specific application notes available from
