Mem_test Software Application 
Revision 1.00
------------------------------

Application Summary:
	This program checks the memory locations B0, B1, B2, and external 
	data memory of the F240 EVM Development Board.  This program checks 
	the memory locations using the "checker board" method (i.e. storing
	5555h in a location, then AAAAh).  By using the "checker board"
	method, this ensures that there is not any leakage of value between 
	adjacent bits.  
			
	The LEDs are used to indicate the results of the test.
	The LEDs flash according to the results.
		1. Start flash - 	Even LEDs (2,4,6,8) 
					then odd LEDs (1,3,5,7)
		2. B0 flash
		3. B1 flash
		4. B2 flash
		5. Data flash
			LEDS DS1-DS4 = Okay; DS5-DS8 = Not Okay

	Errors per block can be viewed in variables	
		B0_ERRORS, B1_ERRORS, B2_ERRORS, DATA_ERRORS
	by using a watch window.

	If an error does occur, the words in memory locations are set 
		HIGH if it fails the test; LOW if it passes test
	Thus, by using a memory window, one can find the location of the
	word that failed the test.
