USART SPI Example for EVK1100 Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the USART in SPI modes software driver.
It also comes bundled with an example. This example is a basic Write to Slave Mode example.
Example's operating mode:

1. A message is displayed on the PC terminal ("Basic write in USART SPI Mode (press enter)")
2. You may then type any character other than CR(Carriage Return) and it will be echoed back to the PC terminal.
3. If you type a CR, the SPI write mode send data through SPI
