Introduction
-------------
This text document accompanies the I2C GPIO Expander CCS test case for DM814X 
EVM. It provides a brief of the methodology of the test and the procedure for 
executing the same.

Overview
---------
This CCS test application accesses the I2C GPIO Expander and carries out the 
following.
	1. Read the User Swicth settings.
	2. Glow the User LED in various patterns
	
The user may verify the physical switch settings against the printed value
for it correctness.

Board Settings
--------------
This test does not require any special settings to be configured on the board.

Procedure
----------
This test application assumes the various initialization as well as all
the PLL initialization is already carried out by the GEL scripts. At the minimum
the following GEL scripts are to be executed.
	 * PG 2.X DM814X                --> ALL_ADPLL_CLOCKS_ENABLE_API 
	 * DM814X System Initialization --> I2C0Enable

load "BB_004_I2C0_GPIO_TEST.out" file and run.
	 	
1. Ensure the swicth position printed in the console reflect the actual settings on 
	the board.
2. Also ensure the User LEDs turning ON and OFF in a pattern.
