Indexes in the range [80 - 103] control the generically named video timing registers, including the image pan/tilt parameters and
line & field length of the sensor. The registers are as follows:
1. line length.
2. x-offset of region of interest.

This register contains a fixed offset that can
be applied to the digitised pixels in the dig-
ital 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[46], bits[1:0] should
be reprogrammed to 2’b1x.
x0 - Accumulate dark pixels, calculate dark
pixel average and report, but don’t apply
anything to data stream
01 - Accumulate dark pixels, calculate dark
pixel average and report and apply
internally calculated offset to data stream
11 - Accumulate dark pixels, calculate dark
pixel average and report, but apply an
externally calculated offset
The dark line offset cancellation algorithm
can opt to only use pixels from dark lines
that are preceeded by another dark line, i.e
line choose only line 306 from line 305 and
line 306.
The deadband describes a range of dark
pixel averages that will force the leaky
integrator algorithm to hold it’s current
value.
