6.2.5. Timing for window of interest
With WS=1, the X and Y start coordinates (WX and WY), and the width and height (WW and WH)
for the window of interest can be programmed with 1 pixel interval. The minimum window size
is 2(h) x 3 (v). If the window is specified outside the full image area, it will be placed up to the
right or low limit as shown in fig 17. right.
Figures marked with (*) in the timing diagrams below will change with other window settings.
