/** @file example_SPI_Master_Slave.c
*   @brief Application main file
*   @date 25.July.2013
*   @version 03.06.00
*
*   This file contains an example of SPI1 and SPI2 Master / Slave configurations.
*
*   PIN Connections must be as Below
*     ---------------         ---------------
*     SPI1 ( Master )          SPI2 ( SLave)
*     ---------------         ---------------
*     SIM0             --->    SIMO
*     S0MI             <---    SOMI
*     CLK              --->    CLK
*     CS0              --->    CS0
*
*  ------------------
*  GUI configurations
*  ------------------
*  1) Driver TAB
*       - Select SPI2
*       - Select SPI1
*  2) VIm Channel 0-31
*       - Enable SPI2 Level 0 and Level 1 channels.
*  3) SPI2 TAB
*       - SPI2 Global SubTAB
*       	- Uncheck Master Mode
*       	- Uncheck Internal Clock
*       - SPI2 Port SubTAB
*       	- Uncheck DIR for CS 0
*  3) SPI1 TAB
*       - Have it default
*  4) Generate Code.
