Although we give the user access to the following 5registers it is not anticipated that the contents of these registers will have to be
altered. If the user does wish to alter any of the register bits then they are strongly advised to contact VIBU before doing so.

This register contains a fixed offset that can be applied to
the digitised pixels in the digital output coding block.The
offset is a 2’s complement number, giving an offset range
-1024,+1023.
If this external offset cancellation is to be applied then it
register[114], bits[1:0] should be reprogrammed to 2’b1x.

x0 - Accumulate black pixels, calculate
black pixel average and report, but don’t
apply anything to data stream
01 - Accumulate black pixels, calculate
black pixel average and report and apply
internally calculated offset to data stream
11 - Accumulate black pixels, calculate
black pixel average and report, but apply an
externally calculated offset
The time constant controls the rate at which
a change in the black level is corrected for.
The deadband describes a range of pixel
averages that will cause the leaky integrator
algorithm to hold it’s current value.
0 - Target +/- 4 codes
1 - Target +/- 2 codes
