Column FPN Correction
The column FPN of the sensor is improved by the offset
correction of the columns. At the start of every frame, before read
out of the actual lines is done, a fixed voltage is applied at the
columns and these values are read out like a real data line. Inside
the data block, the 'pixel' data for that line is stored in an on-chip
FPN memory. When the correction is enabled, the corresponding
FPN value is subtracted from the incoming pixel data.
This FPN correction must be enabled for every output separately.
The registers used to configure the correction are:

datachannelX_1 with X from 0 to 11. The field [1] of these
registers enables the offset corrections of the specific output
channel.
Note Do not change the settings of datachannel12_1. This
channel contains synchronization data, not pixel data. If fpn
correction is enabled on this channel, the synchronization data
becomes corrupt.

of the line of reference voltages at the columns.
