F-bit mode [1:0]

VPLL: VPLL time constant control

0 = VPLL adapts the time constant to the input signal (default) 1 = VPLL time constants are fixed

Adaptive:

0 = Enable F-bit and V-bit adaptation to detected lines per frame (default) 1 = Disable F-bit and V-bit adaptation to detected lines per frame

F-bit mode [1:0]:

00 = Auto mode. If lines per frame is standard decoded F and V bits as per 656 standard from line count else decode F bit from VSYNC input and set V-bit = 0 (default).

01 = Decode F and V bits from input syncs 10 = Reserved

11 = Always decode F and V bits from line count

This register is used in conjunction with the F-bit and V-bit control 2 register (subaddress 75h) as indicated below:
