AVID stop [9:8]

AVID stop [9:0]: AVID stop pixel number. The number of pixels of active video must be an even number. This is an absolute pixel location from HSYNC start pixel 0.

The TVP5147M1 decoder updates the AVID stop only when the AVID stop MSB byte is written to. If the user changes these registers, then the TVP5147M1 decoder retains values in different modes until this device resets. The AVID start pixel register also controls the position of the EAV code.
