Restart
MT9P001: 1/2.5-Inch 5Mp Digital Image Sensor
Features
Note:
To restart the MT9P001 at any time during the operation of the sensor, write a “1” to the
restart register (R0x0B[0] = 1). This has two effects: first, the current frame is interrupted
immediately. Second, any writes to frame-synchronized registers and the shutter width
registers take effect immediately, and a new frame starts (in continuous mode). Register
updates being held by synchronize_changes do not take effect until that bit is cleared.
The current row and one following row complete before the new frame is started, so the
time between issuing the Restart and the beginning of the next frame can vary by about
t_ROW.
If Pause_Restart is set, rather than immediately beginning the next frame after a restart
in continuous mode, the sensor pauses at the beginning of the next frame until
Pause_Restart is cleared. This can be used to achieve a deterministic time period from
clearing the Pause_Restart bit to the beginning of the first frame, meaning that the
controller does not need to be tightly synchronized to LV or FV.
When Pause_Restart is cleared, be sure to leave Restart set to “1” for proper operation.
The Restart bit will be cleared automatically by the device.
