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 scans.

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.
