In situation S2
before servicing of a previous trigger event is complete. The trigger
overrun bit is again set, but the additional trigger events are otherwise
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 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.
