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)
