In the absence of AIN signal input, output will be black data (Y=0x10, Cb/Cr=0x80).
(Blueback output can be obtained by register setting).

The above supply voltages are referenced to ground pins (DVSS=AVSS) at 0V (Reference Voltage).
All power supply grounds (AVSS, DVSS) should be at the same electric potential.
If digital output pins are connected to data bus, the data bus operating voltage should be in the same range as
shown above from the digital output pin.
The setting other than above may cause the eternal destruction to the deivce.
Normal operational is not guaranteed for the above setting.
