# AVR®32 AT32AP7000 Software Framework: the Synchronous Serial Controller (SSC)

Copyright © 2006-2008 Atmel Corporation

## Introduction

The Atmel Synchronous Serial Controller (SSC) provides a synchronous communication link with external devices. It supports many serial synchronous communication protocols generally used in audio and telecom applications such as I2S, Short Frame Sync, Long Frame Sync, etc.

## Synchronous Links SSC Drivers

Because the SSC supports many serial synchronous communication protocols, the SSC folder will hold several drivers (one driver per protocol). The amount of SSC drivers provided in the Software Framework will increase over time.

- I2S mode API driver: this driver example shows how to use the SSC in the I2S protocol mode (serial communication mode used in audio or high speed serial links.).
