PIX_GRABBER
Access: Read/Write
Data Type: 8-bit number.
USAGE: The pixel grabber captures 1 pixel per frame. If there is a valid pixel in the grabber when this is read, the MSB will

be set, an internal counter will incremented to captured the next pixel and the grabber will be armed to capture
the next pixel. It will take 576 reads to upload the completed image. For each pixel read, the register should be
polled (continuously read) until VALID = 1 before the PG [6:0] is taken as valid pixel data. Any write to this register
will reset and arm the grabber to grab pixel 0 on the next image.
The X and Y directions with respect to the mouse case are shown in Figure 27.See pixel array numbering in
Figure 28 that shows the readout order of the array. Rows are read from bottom to top and columns are from
left to right.
