CGAIN 4 [3:0]:
Coarse Gain = 0.5 + (CGAIN 4)/10 where 0

This fine gain applies to component Pb.
Fine Gain = (1/2048) × FGAIN 1, where 0
≤ FGAIN 1 ≤ 4095
This register is only updated when the MSB (register 4Bh) is written to.
This register works only in manual gain control mode. When AGC is active, writing to any value is ignored.
