R Channel Offset Adjustment - auto controlled by internal circuit if
COMG[0] = 1 (see
Luminance Signal High Range for AEC/AGC Operation
Luminance Signal Low Range for AEC/AGC Operation
Fast Mode Large Step Range Thresholds - effective only in AEC/AGC
fast mode (COMI[7] = 1, see
AEC/AGC may change in larger steps when luminance average is
greater than VV[7:4] or less than VV[3:0].
B Channel Offset Manual Adjustment Value - effective only when
COMG[3] = 1 (see
Gb Channel Offset Manual Adjustment Value - effective only when
COMG[3] = 1 (see
Gr Channel Offset Manual Adjustment Value - effective only when
COMG[3] = 1 (see

Bit[7]:
Bit[6:0]: R channel offset adjustment value
AEC/AGC values will decrease in auto mode when average
luminance is greater than AEW[7:0]
AEC/AGC values will increase in auto mode when average
luminance is less than AEB[7:0].
