	This sample program is used with the BL2100 series controllers.

	This program demonstrates how to access the A/D internal test voltages
	in the TLC2543 A/D chips. The program reads the A/D internal voltages
	and then displays the RAW data in the STDIO window. 

	Instructions:
	-------------

	1. Compile and run this program.
	2. The program will display the raw data for a given internal test
	   channel.
	   
	   A/D Channel 								 TLC2543	  	
      ---------------------------------    -------		
	   channel 11  =  (Vref+  - Vref-)/2     0x800      
	   channel 12  =  Vref-						  0x000      
	   channel 13  =  Vref+						  0xFFF
