Product data sheet
9.3 Offset registers (R, G and B)
The offset registers contain a 9-bit value which controls the clamp level for the RGB
channels. The 8 LSBs are in the offset registers and the 1 MSB is in the coarse gain
control register. The relationship between the programming code and the level of the
clamp code is given in
