PU0
System Power Up or Sensor Hot Plugged
PU1
Sensor Internal-on Reset Triggers, the sensor enters low power mode and D[3:0] is set
to F
H
.
PU2
Video Processor released from reset.
PU3
Video Processor enables the sensor clock, CLKI.
PU4-PU5
At least 16 CLKI clock periods after CLKI has been enabled the VP sends a “Soft-Reset”
command to the sensor via the serial interface. This ensures that if a sensor is present
then it is in low-power mode.
PU6
On detecting 32 consecutive F
H
values on D[3:0], the Video Processor sets the
no_camera low.
PU7-PU8
If present, upload the sensor defect map from E
2
PROM into the Video Processor
PU9
Video Processor disables the sensor clock, CLKI.
PU10
Video Processor generates the VP_Ready interrupt.
PU11
The host software services the VP_Ready interrupt.
PU12
Host issues command to remove sensor from low-power mode. VP enables the sensor
clock, CLKI.
PU13-PU4
At least 16 CLKI clock periods after CLKI has been enabled the VP sends the “Exit Low-
Power Mode” command to the sensor via the serial interface. This initiates the sensors
4 frame start sequence.
PU15-PU16
One frame of alternating 9
H
& 6
H
data on D[3:0] for the video processor to determine the
best sampling phase for the nibble data (D[3:0]).
PU17-PU18
4 Frames after the “Exit Low-Power Mode” serial comms, the sensor starts outputing
valid video data.
