When the sensor is put into Force Rest function via F_Rest[1:0], the operation mode of sensor will change from
current mode to the next desired Rest mode and stay at the desired Rest mode until the Force Rest mode is
released. Once Force Rest mode is released, the sensor will resume to normal operation from the desired Rest
mode and auto downshift to the next level of Rest modes if no motion or recover to Run mode if motion is
detected.

Description
Puts chip into Rest mode
00 = Normal operation
01 = Force Rest1
10 = Force Rest2
11 = Force Rest3
Enable Rest mode
0 = Normal operation without REST modes
1 = REST modes enabled
Disable AGC. Shutter value will be set to the value in the Shutter_Maximum_Bound registers.
0 = no, AGC is active
1 = yes, AGC is disabled
Fixed frame rate (disable automatic frame rate control). When this bit is set the frame rate will be
set by the value in the Frame_Period_Maximum_Bound registers.
0 = automatic frame rate
1 = fixed frame rate
Select CPI reporting mode.
0 = XY axes CPI setting in sync
1 = CPI setting independently for X-axis and Y-axis. Configuration_I register sets X-axis resolution,
while Configuration_V register sets Y-axis resolution.
Must be set to 00

After Force Rest mode is released (F_Rest[1:0] = 00)
Resume to normal operation from REST1, auto downshift to Rest2,
then Rest3 in sequence if no motion or back to Run mode if motion
detected.
Resume to normal operation from REST2, auto downshift to Rest3 if
no motion or back to Run mode if motion detected.
Resume to normal operation from REST3, stay in Rest3 if no motion
or back to Run mode if motion detected.
