Figure 13-31. CCW Priority Situation 5
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.
In situation S6 (
), the conversion initiated by the second CCW in queue 2 is aborted just
before the conversion is complete, so that queue 1 execution can begin. Queue 2 is considered suspended.
After queue 1 is finished, queue 2 starts over with the first CCW, when the RES (resume) control bit is set
to 0. Situation S7 (
) shows that when pause operation is not in use with queue 2, queue 2
suspension works the same way.
