RPGA[9:0] is used to set the gain of the Programmable Gain Amplifier (PGA) for the red channel.
Code = 0000000000 is minimum gain. Code = 1111111111 is maximum gain.

RDOFF[9:0] sets the course offset level prior to the PGA of the Red channel. Code = 0000000000 is -80mV.
Code =1111111111 is +160mV. Default is Code 0101010101 = 0 mV.
