10.2.3 Pulse Width Control trigger mode
In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to have
a long time exposure. The maximum recommended time is <2 seconds.
The accumulation can be LVAL synchronous or LVAL asynchronous.
The resulting video signal will start to be read out after the trigger rising edge.
For timing details, refer to fig. 19 through fig. 24 and fig. 30 through 31.
To use this mode:
