OFD output control (D7 to D0).
Cut-off frequency of CDS and AGC. Only the 4 LSBs (D3 to D0) are used for
CDS. D4 to D7 are used for AGC. D8 and D9 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. Edge control for pulses SHP, SHD, CLAMP and
clock ADC:
Clamp reference DAC (D9 to D0).
D0 = 1: CDS + AGC in standby; I
D1 = 1: OFD DAC in standby; I
D2 = 1: 6 dB amplifier (output on AMPOUT pin) in standby;

D3 = 1: SHP and SHD activated with falling edge (for positive pulse)
D4 = 1: CLPDM, CLPOB and CLPADC activated on HIGH level; note 1
D5 = 0: CLKADC activated with falling edge
D6 must be set to logic 0.
