Critical Fault bits – If these bits are anything other than zero, return the module to the factory for repair.
07 (07) Unused – set to 0
08 (10) Calibration Range bit – set to 1 if a reference signal is out of range during calibration
09 (11) Calibration Done bit – set to 1 after an initiated calibration cycle is complete.
10 (12) Calibration Bad bit – set to 1 if the channel has not had a valid calibration.
11–15 (13–17) Unused – set to 0

Bit 02 (02) Fixed Digital Filter – When this bit is set (1), a software digital filter is enabled. This filter settles to
100% of a Full Scale step input in 60 times the selected first notch filter time shown on page 4–3.
Default – filter disabled.

06 (06) Calibration High/Low bit – This bit is set during gain calibration; reset during offset calibration.
07 (07) Calibration clock – this bit must be set to 1 to prepare for a calibration cycle; then reset to 0 to initiate
calibration.
08–15 (10–17) Calibration mask – The channel, or channels, to be calibrated will have the correct mask bit set. Bit 8
corresponds to channel 0, bit 9 to channel 1, and so on.
