The
vector that contains the per-column offset adjustment
used to eliminate column based offset FPN. This RAM
is automatically loaded with internally generated data
upon initialization and can be automatically reloaded as
defined earlier in this section.
The user can generate the DOVA RAM contents and
then load them into the RAM by performing a repetitive
write cycle to the same I

Description
Description
column 0 to column 703 where column 0 is defined as
the left-most column of the pixel array. The user should
set and reset the cntr bit of the
Register, prior to loading the Column DOVA RAM to as-
sure proper addressing.
When the user is calculating values to be loaded into
the DOVA RAM, the fixed gain of 2x in the ASP after
the Column DOVA circuit must be taken into account.
Therefore, each code value in the DOVA RAM repre-
sents 2 code values in the 10-bit ADC output.
