000 = 16-bit 4:2:2 YCbCr
001 = 8-bit 4:2:2 YCbCr
010 = 8-bit BT.656
011 = 15-bit RGB
100 = 16-bit RGB
101 = reserved
110 = reserved
111 = reserved
These bits are ignored except during RGB output modes.
00 = Linear RGB (gamma of input source = 2.2)
01 = Linear RGB (gamma of input source = 2.8)
10 = Gamma-corrected RGB (gamma = gamma of input source)
11 = reserved
00 = Normal operation
01 = Output blue field
10 = Output black field
11 = Output 75% color bars
This bit specifies whether or not the chrominance pixels have a half-
line pixel offset from their associated luminance pixels.
0 = Half-line offset
1 = Aligned
This 8-bit register specifies the last two digits of the product number.
It is a read-only register. Data written to it is ignored.
These bits are read only unless D4 = “0”.
00 = (M) NTSC
01 = (B, D, G, H, I, N) PAL
10 = (M) PAL
11 = Combination (N) PAL; also called (N
0 = Manual selection of video timing standard
1 = Auto detect of video timing standard
Typically, this bit should be a “1” during (M) NTSC and (M, N) PAL
operation. Otherwise, it should be a “0”.
0 = Video source has a 0 IRE blanking pedestal
1 = Video source has a 7.5 IRE blanking pedestal
This bit specifies whether to use fixed or adaptive sync slicing. Adap-
tive sync slicing automatically determines the mid-point of the sync
amplitude to determine timing.
0 = Fixed sync slicing
1 = Adaptive sync slicing
