7.3.5 Pulse Width trigger mode
In this mode, the accumulation time is equal to the trigger pulse width. Here it is possible to
have long exposure times. For the best image quality, the maximum recommended time is <60
frames (2 seconds), however longer exposures may produce acceptable results depending on
the application.
For timing details, refer to fig. 19 through fig. 26 and fig. 29.
