65296
Vertical boundaries of AE measurement window.
7:0
16
Bottom window boundary.
15:8
255
Top window boundary.
This register specifies top and bottom boundaries of the window used by AE
measurement engine. The values programmed in the registers are desired boundaries
divided by two.

Horizontal boundaries of AE measurement window for back light compensation.
7:0
40
Left window boundary.
15:8
120
Right window boundary.
This register specifies left and right boundaries of the window used by AE
measurement engine in backlight compensation mode, see Reg6[3:2]. The values
programmed in the registers are desired boundaries divided by four.
