File Name:				Main.c

Date Modified:			10/25/04				Rev 0.2

Software:       		VisualDSP++4.5

Hardware:				BF533 EZ-KIT Board

Special Connections:  	Connect a CVBS video source to the right bottom video jack "AVIN1"
                        change switch #6 of SW3 to on of the ADSP-BF533 EZ-KIT Lite.
						

Purpose:				After reset the ADV7183 is configured to output digital
						video data in ITU656 mode 8bits wide. Additionally, The DSP is 
						configured to receive video data in ITU-656 format via the PPI Interface.
						The DMA channel 0 is dedicated to transfer the data to the 
						external SDRAM immediately (Address 0x0).
