Synchronization Timing
Genie supports two types of sensor synchronization, used to align the exposure to sensor timing:

Synchronous Mode: Exposure is synchronous to the line timing of the sensor. Exposure granularity is 1µs and
the readout can be concurrent to the exposure for the fastest possible frame rate.

Reset Mode: Timing is reset to initiate exposure of next frame. Exposure granularity is 1µs, but readout must
be sequential to exposure, reducing the maximum achievable frame rate.
Synchronous Mode

Synchronous mode starts the exposure period aligned to the sensor horizontal line timing and the programmable
duration granularity is 1µs.

In the case of the Genie C640, a horizontal line occurs every 31.77µs.

Exposure duration is from the sensor minimum (see Genie Sensor Overview) up to 16 sec.

In this mode, sensor exposure and sensor readout of the previous frame's exposure occur simultaneously. This
allows operating the sensor up to its maximum frame rate.

Any trigger received before the end of the exposure is ignored. The application can elect to receive messages
about ignored triggers. See "Events" on page 69.

Since the external trigger is asynchronous with the Genie horizontal line timing, the frame exposure start is
subject to 1 horizontal line jitter.
