Using the ADSP-BF561 Blackfin Processor as a TFT-LCD Controller

File Name:		Init_Timers.c

Date Modified:	5/1/05		CL		Rev 1.0

Software:       VisualDSP++3.5

Hardware:		ADSP-BF561 EZ-KIT Lite

Special Connections:  None

Purpose:		This file initializes the timers.  Several of the general
			purpose timers are used in PWM_OUT mode to generate the 
			required timing waveforms that the LCD ordinarily requires
			from an external timing ASIC.  Because of the abundance of
			general purpose timers on the ADSP-BF561 Blackfin Processors,
			the timing ASIC was eliminated.
