0x6D
9:0 128
Digital Gain 1 for Blue Pixels
Default setting 128 corresponds to gain value of 1. Gain scales linearly with value.
110
0x6E
9:0 128
Digital Gain 1 for All Colors
Write 128 to set all gains (R106-R109) to 1. When read, this register returns the value of R107.
122
0x7A
15:0 80
Boundaries of Flicker Measurement Window (Left/Width)
7:0 80
Window width.
15:8 0
Left window boundary.
This register specifies the boundaries of the window used by the flicker measurement engine. The values
programmed in the registers are the desired boundaries divided by 8.
123
0x7B
15:0 0x0088
Boundaries of Flicker Measurement Window (Top/Height)
5:0 8
Window height.
15:6 2
Top window boundary.
This register specifies the boundaries of the window used by the flicker measurement engine.
124
0x7C
15:0 5120
Flicker Measurement Window Size
This register specifies the number of pixels in the window used by the flicker measurement engine.

1 = blank outgoing frames. When set, current frame completes and following frames
are not output, FEN = LEN = 0. When unset, output resumes with the next frame. The
bit is synchronized with frame enable. See freeze bit (R152[7]).
