Data Type: High 8 bits of an unsigned 17-bit integer.

USAGE: This register is used to find the average pixel value.

It reports the seven bits of a 16-

bit counter, which sums all pixels in the current frame. It may be described as the full sum

divided by 512. To find the average pixel value, use the following formula:

Average Pixel = Register Value * 128/121 = Register Value * 1.06

The maximum register value is 240. The minimum is 0. The pixel sum value can change on every

frame.
