Set to the same value as register Data Pixels Start.
n pixels (0 - 16383)
This selects the pixel count at which the current line is
ended and the next line begins. This determines the
integration time of one line.
n pixels (Active Pixels Start - 16383)
This selects the start of the range of pixels transmitted
to the PC and determines the pixel location where
offset and shading correction begins (pixel 0 in the
DataPort). This value must be >= Active Pixels Start
This selects the end of the range of pixels transmitted
to the PC. This value must be <= [Line End - 20]
