Saturation[7:0]
Saturation[7:0]: This register works for CVBS and S-Video chrominance.
1111 1111 = 255 (maximum)
1000 0000 = 128 (default)
0000 0000 = 0 (no color)
The total chrominance gain relative to the nominal chrominance gain as a function of the Saturation[7:0]
setting is as follows:
Chrominance Gain = nominal_chrominance_gain × (Saturation[7:0] / 128)

Contrast [7:0]
Contrast [7:0]: This register works for CVBS and S-Video luminance.
1111 1111 – 1101 0000 = Reserved
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.
