USART Loopback Example for AT32UC3A0512 in AVR Simulator Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the USART software driver.
It also comes bundled with an example. This is a basic example for use with AVR Studio 5 Simulator.
Example's operating mode:

1. Add test_out and test_in to the Watch window
2. Place breakpoint in usart_getchar() function
3. The test data sent will be echoed back to the Receiver
