Contrast [7:0]
Contrast [7:0]: This register works for CVBS and S-Video luminance.
1111 1111 to 1101 Reserved
0000 =
1100 1111 = 207 (maximum contrast)
1000 0000 = 128 (default)
0000 0000 = 0 (minimum contrast)
The total luminance gain relative to the nominal luminance gain as a function of the Contrast [7:0] setting is as follows.
Luminance Gain = nominal_luminance_gain × (Contrast[7:0] / 128)
Note: Luminance peak processing (see bit 1 of subaddress: 02h) may limit the upper end of the contrast control range.
Note: Whenever the contrast control setting is modified, the brightness control setting must be modified immediately afterward to maintain
the proper output black level.

YCbCr output code range:
0 = ITU-R BT.601 coding range (Y ranges from 16 to 235. U and V range from 16 to 240)
1 = Extended coding range (Y, U, and V range from 1 to 254) (default)
CbCr code format:
0 = Offset binary code (2s complement + 128) (default)
1 = Straight binary code (2s complement)
YCbCr data path bypass:
00 = Normal operation (default)
01 = Decimation filter output connects directly to the YCbCr output pins. This data is similar to the digitized composite data, but
the HBLANK area is replaced with ITU-R BT.656 digital blanking.
10 = Digitized composite (or digitized S-video luma). A/D output connects directly to the YCbCr output pins.
11 = Reserved
YCbCr output format:
000 = 8-bit 4:2:2 YCbCr with discrete sync output
001 = Reserved
010 = Reserved
011 = Reserved
100 = Reserved
101 = Reserved
110 = Reserved
111 = 8-bit ITU-R BT.656 interface with embedded sync output (default)
