Active Pixels:
This register should be programmed with the pixel number of
the first active pixel to be read out. That is the first pixel after the extra pixels,
the black pixels, and the grey pixel.
This register value is used by the CS7620 when the part is in the valid data
mode to generate the data valid signal on the CLKO pin.
Valid data can be set through the above mentioned registers together with
act_begin(1Fh) to define a subset of pixels to be passed to the subsequent
ASIC or DSP component. This subset may or may not include dark rows
and/or dark pixels. Please refer to Figure 28.
The default value is set to 75, which is the sum of the blk_end register (1Dh)
and act_rws_lst register (1Eh).

Critical Timing:
This determines the width of the minimum vertical division
measured in pixel clocks. (One vertical pixel shift (row) requires 8 vertical time
division slots) See Figure 33.
