Data Type:

High 8-bits of an unsigned 16-bit integer.

USAGE:

This register stores the accumulated pixel value of the last image taken. This register can be

used to find the average pixel value, where Average Pixel = (register value AP[7:0]) * 0.71

The maximum accumulated value is 45847 but only bits [15:8] are reported, therefore the

maximum register value is 179. The minimum is 0. The PIX_ACCUM value may vary with

different frame.
