The explanation for IIC Bus
*Sub address 00h(D7-D6), 01h(D0) ADC power save mode
It can save the power automatically depending on the kind of input signal.
When it is not use the ADC, it can stop working ADC.
*Sub address 01h(D7-D6) 3D DET
It can switch preset mode for motion detection.
00: Preset mode for 3D YC separation
01: Preset mode for 3D NR
10: 3 line comb mode (NR off)
11: manual mode (It is available sub address 10h – 1Ah)
