delay parameter represents the time from the external trigger to strobe pulse assertion.

In Slow Strobe mode, the strobe pulse occurs after a certain delay following the FVAL

and the trigger, respectively. Strobe duration is programmable. See below for diagram.

Basically, the strobe pulse is asserted from the first FVAL following the trigger. This

mode is often used with free-running cameras.
