Q DAC sleep
1 = puts the Q DAC into sleep mode (fast wake-up mode).
0
[1:0]
Q DAC FS Adj[9:8]
Q DAC FS Adj[9:0] sets the full-scale current of the Q DAC.
The full-scale current can be adjusted from 8.64 mA to
31.68 mA in step sizes of approximately 22.5 A.
01
0x000 = 8.64 mA.
…
0x200 = 20.16 mA.
…
0x3FF = 31.68 mA.

Q aux DAC sign
0 = the Q auxiliary DAC sign is positive, and the current is
directed to the IOUT2P pin (Pin 38).
0
1 = the Q auxiliary DAC sign is negative, and the current is
directed to the IOUT2N pin (Pin 39).
6
Q aux DAC current
direction
0 = the Q auxiliary DAC sources current.
0
1 = the Q auxiliary DAC sinks current.
5
Q aux DAC sleep
1 = puts the Q auxiliary DAC into sleep mode.
0
[1:0]
Q Aux DAC[9:8]
Q Aux DAC[9:0] sets the magnitude of the auxiliary DAC
current. The range is 0 mA to 2 mA, and the step size is 2 A.
00
0x000 = 0.000 mA.
0x001 = 0.002 mA.

SED compare enable
1 = enable the SED circuitry. None of the flags in this
register or the values in Register 0x70 through
Register 0x73 are significant if the SED is not enabled.
0
5
Sample error detected
1 = indicates an error was detected. The bit remains set until
cleared. Any write to this register clears this bit to 0.
0
3
Autoclear enable
1 = enable autoclear mode. This activates Bit 1 and Bit 0 of
this register and causes Register 0x70 through Register 0x73
to be autocleared when eight consecutive sample data sets
are received error free.
0
1
Compare fail
1 = indicates an error was detected. This bit remains set until
it is autocleared by the reception of eight consecutive error-
free comparisons or is cleared by a write to this register.
0
Compare pass
1 = indicates that the last sample comparison was error free.
