Analog calibration offset for green1 pixels, represented as a two’s complement signed 8-bit value (if bit 8 is clear, the offset is
positive and the magnitude is given by bits 7:0. If bit 8 is set, the offset is negative and the magnitude is given by not ([7:0]) +
1). If R0x60[0] = 0, this register is R/O and returns the current value computed by the black level calibration algorithm. If
R0x60[0] = 1, this register is R/W and can be used to set the calibration offset manually. Green1 pixels share rows with red
pixels.
15:0
Analog calibration offset for green2 pixels, represented as a two’s complement signed 8-bit value (if bit 8 is clear, the offset is
positive and the magnitude is given by bits 7:0. If bit 8 is set, the offset is negative and the magnitude is given by not ([7:0]) +
1.) If R0x60[0] = 0, this register is R/O and returns the current value computed by the black level calibration algorithm. If
R0x60[0] = 1, this register is R/W and can be used to manually set the calibration offset. Green2 pixels share rows with blue
pixels.

Disable Fast Sample
Lock Green Calibration
Lock Green Calibration—when set, only one calibration value will be used for both Green1 and
Green2 channels. Default is 0, set to “0” at all times.
Note: Gain for Green1 and Green2 channels must be equal for setting to be effective.
Lock Red/Blue Calibration
Lock Red/Blue Calibration—when set, only one calibration value will be used for both red and blue
channels. Default is 0, set to “0” at all times.
Note: Gain for Red and Blue channels must be equal for setting to be effective.
Recalculate BL
Recalculate Black Level—1 = start a new running digitally filtered average for the black level (this is
internally reset to “0” immediately), and do a rapid sweep to find the new starting point.
0 = normal operation (default).
