OFDOUT output control (D7 to D0).
Soft clipper control. Only the 4 LSBs (D3 to D0) are used. Bits D9 to D4 should be set to
logic 0.
AGC gain control (D8 to D0).
Partial standby controls for power consumption optimization. Only the 4 LSBs (D3 to D0)
are used. Bits D9 to D4 should be set to logic 0:
Clamp reference DAC (D9 to D0).
D0 = 1: CDS + AGC + soft clipper block in standby; I
D1 = 1: optical black clamp + blanking block in standby; I
D2 = 1: OFD DAC in standby; I
D3 = 1: 6 dB amplifier (output on AMPOUT pin) in standby; I
