Mode 0 (CCIR–656): Slave Option
(Timing Register 0 TR0 = X X X X X 0 0 0)
The ADV7190/ADV7191 is controlled by the SAV (Start Active Video) and EAV (End Active Video) Time Codes in the Pixel
Data. All timing information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately
before and after each line during active picture and retrace. Mode 0 is illustrated in Figure 33. The
HSYNC
,
VSYNC
and
BLANK
pins (if not used) should be tied high during this mode.
