The Atmel® Software Framework (ASF) is a collection of free embedded software for Atmel microcontroller devices.

It simplifies the usage of Atmel products, providing an abstraction to the hardware and high-value middleware.

ASF is designed to be used for evaluation, prototyping, design and production phases. ASF is integrated in the Atmel Studio IDE with a graphical user interface or available as a standalone package for several commercial and open source compilers.

This document describes the API interfaces to the low level ASF module drivers of the device.

For more information on ASF refer to the online documentation at www.atmel.com/asf.
