Device operating modes
Power-up
On power up the sensor is in low-power mode. All data bus lines drive high to indicate that the
device is “present”.
Waking up the sensor
The sensor is made to exit low power mode by enabling the external clock and writing to SIF
register16 bit 0. The first frame output after exiting low-power mode does not contain any valid video
data.
Low power mode
Entering low-power mode during video streaming causes the analogue circuits to be powered
down. The values of the serial interface registers is preserved.
