Triggering during the Readout State

For applications requiring the fastest triggering cycle time whereby the camera image sensor is
exposing and reading out simultaneously, then the User Trigger signal should be applied as
soon as a valid Trigger Ready is detected.

In this case, Trigger Latency and Trigger Jitter can be up to 1 line time since Exposure must
always begin on an Interline boundary.
