8.8
Please note that the following descriptions of low power and sleep modes assumes that the user has selected the optional 4 wire
output mode, that is D[3:0] will transmit the digital video data. If the 5-wire or 8-wire modes are selected the same basic behaviour
is followed however the contents of the data bus will differ slightly.
8.8.1
The sensor enters low-power mode on power-up. On power-up all of the data bus lines are driven high immediately and the
device is in low-power mode (Section 8.8.2).
The sensor will remain in the low power mode until the external host sends the appropriate message over I2C to clear the low
power bit - bit0 of serial reguister, setup0, index 10
After the “Exit Low-Power Mode” command has been sent the sensor will output for one frame, a continuous stream of alternating
9
resulting 0101/1010 patterns appearing on the data bus lines the host can determine the best sampling position for the nibble
data. After the last 9
point the first active video frame will be output. After the host has determined the correct sampling position for the data, it should
then wait for the next start of frame line (SOF).

Sensor enters low power mode and databus bits driven high.
Host enables the sensor clock, CLKI.
The host sends a “Soft-Reset” command to the sensor via the serial interface. This ensures that
the sensor is in low-power mode.
Host issues command to remove sensor from low-power mode.
