Figure 14-27. CCW Priority Situation 3
The next two situations consider trigger events that occur for the lower priority queue 2, while queue 1 is
actively being serviced.
Situation S4 (
) shows that a queue 2 trigger event that is recognized while queue 1 is active
is saved, and as soon as queue 1 is finished, queue 2 servicing begins.
Figure 14-28. CCW Priority Situation 4
Situation S5 (
) shows that when multiple queue 2 trigger 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.
