Full Scale Level:
This is used to set the full scale input range of the CS7622.
Since CCDs have various saturation levels, it is advantageous to set the full
scale input range of the CS7622 to match the saturation level of the CCD used.
The table below shows the full scale level choices. (See Table 4)
Gain Calibration:
A calibration of the gain stages is required to insure a mono-
tonic digital output. If the user wishes to initiate a calibration, he may do so by
setting this bit to ‘1’, which will invoke a gain calibration sequence immediately.
This bit automatically clears itself after a calibration has been initiated. During
the calibration sequence the output will not contain valid data. The input clocks
must be running throughout the whole calibration sequence which lasts for
~760 clocks.
