This register only works in manual gain control mode. When AGC is active, writing to any value is ignored.
F-bit control mode
00 = Auto: If lines per frame is standard decode F and V bits as per 656 standard from line count else decode F bit from vsync input
and set V bit = 0b
01 = Decode F and V bits from input syncs
10 = Reserved
11 = Always decode F and V bits from line count (TVP5146 compatible)
This register is used in conjunction with register 75h as indicated below:
