1) CAMERA PARAMETER READ
SPI Write "data set" (send to camera MCU), Address:0x082
Checksum (CS) specifies the lower 1 byte of the calculated value (C1 + C2 + ADR + DAT).
In the PARAMETER READ command (address:0x082) , it will be 0x87 fixed value.
SPI Write "data set" (send to camera MCU), Address:0x193
Checksum (CS) specifies the lower 1 byte of the calculated value (C1 + C2 + ADR + DAT).
In the PARAMETER READ command (address:0x193) , it will be 0x99 fixed value.
SPI Read "data set" (camera MCU response)
*1: Parameter address lower byte. Same as SPI Write data.

Camera Parameter
*Factory setting value: 0x00
By using DIGIT OUT(0x5E2:Bit0), the digital output will be turned ON/OFF.
Since no other parameters are allocated in this address, digital output turning ON or OFF is possible by sending
data 0x01(ON) or 0x00(OFF).
e.g.1) turn ON the digital output function
Send following data bytes to the indirect registers for SPI control (address: 0x0036 to 0x003B).
e.g.2) turn OFF the digital output function
Send following data bytes to the indirect registers for SPI control (address: 0x0036 to 0x003B).

5.2.2 COLOR ID (COLOR ID)
By using the bit-4 and 5, the data output order of the digital output signal bit 7 to 0
(connector: J6, pin number: 6-12) are changed.
Camera Parameter
*Factory setting value: 0x47
By using Bit-4, the output order of the chroma signal(Cb,Cr) and the luminance signal(Y) is changed.
By using Bit-5, the output order of the chroma signal(Cb) and the chroma signal(Cr) is changed.
(Since WAT-910BD is a B/W camera, bit-5 is invalid for substantially, and the data values of Cb and Cr are
all 0x80.)
The factory setting value is (bit-5, bit-4) = (0,0), it means that the digital data order are (Cb, Y, Cr, Y).
*1) COLOR ID=0 (factory setting) or 2:
The digital video data order are 0x80, Yn, 0x80, Yn+1…
DCK
*1) COLOR ID=1 or 3:
The digital video data order are Yn, 0x80, Yn+1, 0x80…
DCK
e.g.4) To change the order of the digital data to "luminance data first output".
(digital output ON, others are left at the default setting)
The data byte to be transmitted to the digital output setting(address: 0x193) is 0xD7.
Send following data bytes to the indirect registers for SPI control (address: 0x0036 to 0x003B).
