uwCoarseIntegrationPending_lines
0x1209(MSByte)
0x120a(LSByte) Purpose
Type
The course period of time over which every pixel is integrating is a
multiple of the number of lines times the number of pixels on the line
times the pixel period. These registers show the number of lines of
integration which will be used for the next frame.

uwFineIntegrationPending_pixels
Purpose
Type
The fine period of integration is detailed as a added of
