BIT
NAME
DESCRIPTION
D9
STBY
Device power down control: 1 = standby, 0 = active (default)
D8
PDD1
Power down the user DAC1: 1 = standby, 0 = active (default)
D7
PDD2
Power down the user DAC2: 1 = standby, 0 = active (default)
D6
ACD
Coarse offset DAC mode control:
0 = Auto calibration (default)
1 = Bypass auto calibration
Note: When D6 is set to 0, D5 must also be set to 0 (auto mode); otherwise, the
auto mode will be disabled on both offset DACs.
D5
AFD
Fine offset DAC mode control:
0 = Auto calibration (default)
1 = Bypass auto calibration
Note: D5 can be set to 0 with or without D6 being set to 0.

Reserved
D1
RTOB
A write of a 1 to this bit resets the calculated black level results in the digital averager.
D0
RTSY
A write of a 1 to this bit resets the entire system to the default settings.
