Offset Register
There are three PGA registers for individually programming the offset in the red, green, and blue channels. Bits D8
through D0 control the offset range from -250mV to +250mV in 512 increments. The coding for the offset registers is
sign magnitude, with D8 as the sign bit. Table shows the offset range as a function of the Bits D8 through D0.
