AUTO_SLEEP3_

LATENCY

ucSleep3Latency

7:0

Maximum latency to wake up

the system in SLEEP3 state.

Corresponds to the time

between two wake-up periods

(a wake-up period corresponds

to a single frame motion

detection processing).

0 = 400 us

1 = 1 ms

2 = 1.4 ms

3 = 2 ms

4 = 4 ms

5 = 10 ms

6 = 20 ms

7 = 50 ms

8 = 100 ms

9 = 150 ms

10 = 200 ms

11 = 500 ms

12 = 1 s

13 = 1.5 s

14 = 2 s

15 = 2.6 s

CTRL1

bAutoMoveFilterEnab

0RW

Auto movement filter enable

0 = Disable

1 = Enable

ucAutoMoveFilterFra

meNb

6:1

auto movement filter is applied

(must be greater than 1).

bAutoMoveSaturated

Expo

7RW

When image in high light and

exposure (reg 0x47) is set to 1,

flag used by engine to discard

motion in this condition.
