STOP_C_VAR : Contrast Variation with TXT insertion

with this bit, the user saturation and contrast setting will be partially removed i.e. moved

toward contrast = max., saturation = 100% (middle) for TXT/OSD insertion (RTXT,

GTXT, BTXT))

0 : TXT/OSD insertion : same contrast as main channel

1 : TXT/OSD insertion (FBTXT=1) toward max. contrast and mid. saturation

DRV_GAIN

: Selection of gain range (changes the range of the gain adjustement drive)

0 : maximum gain = 4.6

1 : maximum gain = 6.5

S[5..0]

: Color Saturation Adjustment

SATURATION 000000 (hex 00) minimal position = completely suppressed colors
