BIT
NAME
DESCRIPTION
D9
SOF
0 – Normal mode (default)
1 – Start of frame (only used when exposure time is changed)
When this bit is set to 1, next positive ADCCLK edge indicates that next pixel line is the beginning of a new frame.
The optical black correction will be performed with one line averaging only (digital filtering weight = 1) and without
hot/cold pixel limits.
D8–D4
X
Reserved. Set bits to 0.
D3
OBOB
When this bit is set, the averaged optical black value, instead of the data from the blanking data register, appears at
digital output during blanking.
D2–D0
WT2–WT0
These three bits set the weight for digital filtering.
