User-defined “desired bin” that gives a measure of how
bright the image is intended.
The number of frames that the AEC must skip before
updating the exposure register (R0xBB).
This value plays a role in determining the increment/
decrement size of exposure value from frame to frame.
If current bin

Actual new exposure = Calculated new exposure
When Exp LPF = 1:
If |(Calculated new exp - current exp) | > (current exp/4),
Actual new exposure = Calculated new exposure,
otherwise
Actual new exposure = Current exp ± (calculated new
