// TITLE:  SPI Digital Loopback
//
//! \addtogroup driver_example_list
//! <h1>SPI Digital Loopback</h1>
//!
//! This program uses the internal loopback test mode of the SPI module. This
//! is a very basic loopback that does not use the FIFOs or interrupts. A
//! stream of data is sent and then compared to the received stream.
//! The pinmux and SPI modules are configure through the sysconfig file.
//!
//! The sent data looks like this: \n
//!  0000 0001 0002 0003 0004 0005 0006 0007 .... FFFE FFFF 0000
//!
//! This pattern is repeated forever.
//!
//! \b External \b Connections \n
//!  - None
//!
//! \b Watch \b Variables \n
//!  - \b sData - Data to send
//!  - \b rData - Received data
//!
