The MT9V032 works in master, snapshot, or slave mode. In master mode the sensor
generates the readout timing. In snapshot mode it accepts an external trigger to start
integration, then generates the readout timing. In slave mode the sensor accepts both
external integration and readout controls. The integration time is programmed through
the two-wire serial interface during master or snapshot modes, or controlled through
externally generated control signal during slave mode.
There are two possible operation methods for master mode: simultaneous and sequen-
tial. One of these operation modes must be selected through the two-wire serial inter-
face.
In simultaneous master mode, the exposure period occurs during readout. The frame
synchronization waveforms are shown in Figure 13 and Figure 14. The exposure and
readout happen in parallel rather than sequentially, making this the fastest mode of
operation.
