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
111111 (hex 3F) maximal position : maximal saturation (3dB
oversaturation)
