Gain Offset Calibration – This bit is set during gain calibration/ reset during offset calibration.
07
Calibration Clock – This bit must be set to 1 to prepare for a calibration cycle; then reset to 0 to initiate
calibration.

Calibration Mask – The channel, or channels, to be calibrated will have the correct mask bit set. Bit 0
corresponds to channel 0, bit 1 to channel 1, and so on.
