ACT_MODE
0000 : CIF image output with CKI clock of CMOS image sensor
0001 : 1 frame of image output per second with CKI clock
0010 : 2 frames of image output per second with CKI clock
0011 : 15 frames of image output per second with CKI clock
0101 : 1 frame of image output per second with EXCK clock
(1 frame data is written to RAM in vertical blanking.)
0110 : 2 frames of image output per second with EXCK clock
(2 frames data are written to RAM in vertical blanking.)
0111 : Image output with EXMCK clock
(EXMCK should be lower than 4.5 MHz.)
1XXX : Except 0000, works with 30 frames after power-on.
(example) 1001 : 1 frame of image output per second with CKI starting
with 30 frames after power-on.
1000 : Prohibited to use
Setting a period to work with 30 frames after power-on.
A period = (Data + 1) x frame rate

REF_BLC
Exposure reference level in BLC (valid with BLC of address 03h = 1).
The second target area of electronic exposure control in BLC.
In the case that exposure control data is within (data of address 09h ± data of
address 0Ah), the exposure control is completed.

CTLD_02
The first target area of electronic exposure control.
If exposure control data is over (data of address 06h ± data of address 08h), the
exposure control is restarted.
07h

CTLD_01
The second target area of electronic exposure control.
In the case that exposure control data is within (data of address 06h ± data of
address 07h), the exposure control is completed.
06h

REF_IRIS
The first target area of electronic exposure control in BLC.
If exposure control data is over (data of address 09h ± data of address 0Bh), the
exposure control is restarted.
