BIT
NAME
DESCRIPTION
D9
STBY
Device power-down control: 1 = standby, 0 = active (default)
D8
PDD1
Power-down user DAC1: 1 = standby, 0 = active (default)
D7
PDD2
Power-down user DAC2: 1 = standby, 0 = active (default)
D6
ACD
Coarse-offset DAC mode control:
0 = autocalibration (default), 1 = bypass autocalibration.
Note: When D6 is set to 0, D5 must also be set to 0 (automode). Otherwise, the automode will be disabled on both offset DACs.
D5
AFD
Fine offset DAC mode control:
0 = autocalibration (default), 1 = bypass autocalibration.
Note: D5 can be set to 0 with or without D6 being set to 0.
D4
OBM
This bit initiates the offset DAC’s starting sequence.
0 = coarse-offset DAC starts first (default)
1 = fine-offset DAC starts first
D3
X
Reserved
D2
SRSV
This bit specifies the polarity of SR and SV input pulses.
0 – SR/SV active low (default)
1 – SR/SV active high
D1
RTOB
Writing 1 to this bit will reset calculated black-level results in the digital averager.
D0
RTSY
Writing 1 to this bit will reset entire system to the default settings (edge sensitive).
