value may vary with different frame.
data (PG[6:0]) is valid for grabbing. In 22x22 pixel arrays, it will take 484 read operations to grab all the pixels to
form the complete image.
Any write operation into this register will reset the grabber to origin (pixel 0 position). The sensor should not
be moved before the 484 read operations are completed to ensure original data is grabbed to produce good
(uncorrupted) image.
