Auto-trigger with initial trigger and timeout
To optimize the power used by this function, the monitoring can be started by an initial
trigger and can then terminate itself after a selectable time (timeout) or at a falling trigger
edge. Rising trigger edges after the procedure has started are ignored until the result has
been transferred.
In the following example, images are acquired by the trigger until an image has been
recognized and decoded, or until the timeout stops image acquisition.
Trigger initiates the operation.
Trigger signal is ignored.
