Used in conjunction with ED/HD sync output enable in Subaddress 0x02, Bit 7 = 1.
Applies to the ADV7390 and ADV7392 only.
When set to 0, the horizontal/vertical counters automatically wrap around at the end of the line/field/frame of the selected standard. When set to 1, the
horizontal/vertical counters are free running and wrap around when external sync signals indicate to do so.
For use with ED/HD internal test patterns only (Subaddress 0x31, Bit 2 = 1).
