“Soft-Reset” Command. At the end of the command the sensor is reset and enters low-power mode.

The sensor enters low-power mode.

“Exit Low Power Mode” Command. Powers-up analogue circuits and initiates the VM6404 sensor’s 4-frame start-up sequence

1 Frame of alternating 9H & 6H data on D[3:0] for the video processor to determine the best sampling phase for the nibble data

(D[3:0]).

4 Frames after the “Exit Low-Power mode” command, the sensor starts outputing valid video data.
