events are detected while queue 1 is busy, the trigger overrun error bit
is set, but queue 1 execution is not disturbed. Situation S5 also shows
that the effect of queue 2 trigger events during queue 1 execution is the
same when the pause feature is in use in either queue.
The remaining situations, S6 through S11, show the impact of a queue 1
trigger event occurring during queue 2 execution. Queue 1 is higher in
priority, the conversion taking place in queue 2 is aborted, so that there
is not a variable latency time in responding to queue 1 trigger events.
