DAC Software Application 
Revision 1.00
----------------------------

Application Summary:
	Outputs 4 Sine Waves on the EVM DAC through the channels DAC0, DAC1,
	DAC2, and DAC3.  Each sine wave is generated through a look up table
	and interpolation.  

	Each sine wave can be controlled independently. By manipulating the 
	following variables, the frequency, phase, and magnitude of each
	sine wave can be changed.
		FREQSTEPx - modifies the frequency
		MODREGx - modifies the starting point of the sine wave
		MAGx - modifies the peak to peak voltage (Q15 value)
	where x is 0,1,2,3

	The variables can be easily manipulated through a watch window in the 
	debugger environment.
