This register is used to select gain values on RIN, ROUT, SIN and SOUT.
Gains is split into four groups of four bits. Each group maps to a different signal port (as indicated above),
and has three gain bits. The following table indicates how these gain bits are used:
Bit2 Bit1 Bit0 Gain Level
1 1 1

Note that the -12 dB PAD bit in Control Register 1 provides 12 dB of attenuation in the Rin to Rout path, and
will override the settings in Gains.

Functional Description of Register Bits
This register is used to force the NLP off when very small signals exist on RIN. NLP is forced off if RIN is
below NLPTHR2 << 4. Raising this value can help prevent NLP masking at very low signal levels.
