Data Type: Bit Field

USAGE:

This register is used to change configuration of sensor.

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.

For example:

Current

mode

Next desired

mode

Force Rest

mode action

After Force Rest mode is released

(F_Rest[1:0] = 00)

Run

Rest1

Force Rest1

F_Rest[1:0] = 01

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.

Run

Rest2

Force Rest2

F_Rest[1:0] = 10

Resume to normal operation from REST2,

auto downshift to Rest3 if no motion or back to

Run mode if motion detected.

Run

Rest3

Force Rest3

F_Rest[1:0] = 11

Resume to normal operation from REST3,

stay in Rest3 if no motion or back to Run mode if

motion detected.

Field Name

Description

F_Rest[1:0]

Puts chip into Rest mode

00 = Normal operation

01 = Force Rest1

10 = Force Rest2

11 = Force Rest3

Rest_En

Enable Rest mode

0 = Forced awake mode. Normal operation without REST modes.

1 = REST modes enabled

NAGC

Disable AGC. Shutter value will be set to the current shutter value if Rest mode

disabled.

0 = no, AGC is active

1 = yes, AGC is disabled

BIT[3:0]

Must be set to 0x8 (b1000)
