Used in conjunction with HD_SYNC in Register 0x02, Bit 7 set to 1.
When set to 0, the horizontal/vertical counters automatically wrap around at the end of the line/field/frame of the standard selected. When set to 1, the
horizontal/vertical counters are free running and wrap around when external sync signals indicate to do so.
