USAGE: The pixel grabber captures 1 pixel per frame. If there is a valid pixel in the grabber when this register
is read, the MSB will be set, an internal counter will incremented to capture the next pixel and the
grabber will be armed to capture the next pixel. It will take 361 reads to upload the complete image.
Any write to this register will reset and arm the grabber to grab pixel 0 on the next image.
