F-Mode[1:0]
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:

656 = ITU-R BT.656 standard
Pulse = Pulses low for 1 line prior to field transition
Switch = V bit switches high before the F-bit transition and low after the F bit transition
Switch9 = V bit switches high 1 line prior to the F-bit transition, then low after 9 lines
Reserved = Not used
Adaptive
0 = Enable F- and V-bit adaptation to detected lines per frame
1 = Disable F- and V-bit adaptation to detected lines per frame
VPLL time constant control:
0 = VPLL adapts time constants to input signal
1 = VPLL time constants fixed
