In situation S2
trigger event is complete, the trigger overrun bit is again set, but otherwise, the additional trigger events
are ignored. After the queue is complete, the first newly detected trigger event causes queue execution to
begin again. When the trigger event rate is high, a new trigger event can be seen very soon after completion
of the previous queue, leaving software little time to retrieve the previous results. Also, when trigger events
are occurring at a high rate for queue 1, the lower priority queue 2 channels may not get serviced at all.
Situation S3
is set the same way, and that queue execution continues unchanged.
