I.    FUNCTIONAL DESCRIPTION

This program demonstrates the initialization of SDRAM memory 
and the use of the DMA and PPI to input an external analog CVBS signal on ADV7183's input AVIN1.
The output of this program is a color image of 720 x 576 pixels.
 
This example utilizes SDRAM memory to store the video data. The program sets up the DMA and PPI configuration registers for input 
mode, 8-bit, ITU-656, Stop Mode DMA.


II.  OPERATION DESCRIPTION
- Open the project "PAL_Capture.dpj" in the VisualDSP Integrated Development Environment (IDDE).
- Under the "Project" tab, select "Build Project" (program is then loaded automatically into DSP).
- change switch #6 of SW3 to on of the ADSP-BF532-based EZ-KIT Lite.
- Connect the PAL camera to the video input jack AVIN1"at the bottom right" on the ADSP-BF532-based EZ-KIT Lite.
- Select "Run" from the "Debug" tab on the menu bar of VisualDSP.
- Hit the stop button to halt the processor
- Open the Image Viewer "View/Debug Window/Image Viewer". Do following steps:
- Type start address 0x0012FC00; Horizontal Pixels = 720; Vertical Pixels = 576; Pixels per bit = 24; Stride = 1
- Image format = RGB; Hit OK.
