Polarity FID: determines polarity of FID terminal
0 = First field high, second field low (default)
1 = First field low, second field high
Polarity VS: determines polarity of VS terminal
0 = Active low (default)
1 = Active high
Polarity HS: determines polarity of HS terminal
0 = Active low (default)
1 = Active high
VS/VBLK:
0 = VS terminal outputs vertical sync (default)
1 = VS terminal outputs vertical blank
HS/CS:
0 = HS terminal outputs horizontal sync (default)
1 = HS terminal outputs composite sync

Sampling rate

Output format [2:0]
Sampling rate (changing this bit causes the register settings to be reinitialized):
0 = ITU-R BT.601 sampling rate (default)
1 = Square pixel sampling rate
YCbCr code range:
0 = ITU-R BT.601 coding range (Y ranges from 64 to 940. Cb and Cr range from 64 to 960.)
1 = Extended coding range (Y, Cb, and Cr range from 4 to 1016) (default)
CbCr code:
0 = Offset binary code (2s complement + 512) (default)
1 = Straight binary code (2s complement)
Output format [2:0]:
000 = 10-bit 4:2:2 (2
× pixel rate) with embedded syncs (ITU-R BT.656) (default)
001 = 20-bit 4:2:2 (pixel rate) with separate syncs
010 = Reserved
011 = 10-bit 4:2:2 with separate syncs
100–111= Reserved
NOTE: 10-bit mode is also used for the raw VBI output mode when bit 4 (VBI raw) in the
luminance processing control 1 register at subaddress 06h is set (see Section 2.11.7).
