14.4.1
Queue 1 has priority over queue 2 execution. The following cases show the conditions under which queue
1 asserts its priority:
14.4.2
The pause feature can be used to divide queue 1 and/or queue 2 into multiple sub-queues. A sub-queue is
defined by setting the pause bit in the last CCW of the sub-queue.
Figure 14-22
shown with four CCWs in each sub-queue and queue 2 has two CCWs in each sub-queue.

When a queue is not active, a trigger event for queue 1 or queue 2 causes the corresponding queue
execution to begin.
When queue 1 is active and a trigger event occurs for queue 2, queue 2 cannot begin execution until
queue 1 reaches completion or the paused state. The status register records the trigger event by
reporting the queue 2 status as trigger pending. Additional trigger events for queue 2, which occur
before execution can begin, are captured as trigger overruns.
When queue 2 is active and a trigger event occurs for queue 1, the current queue 2 conversion is
aborted. The status register reports the queue 2 status as suspended. Any trigger events occurring
for queue 2 while queue 2 is suspended are captured as trigger overruns. Once queue 1 reaches the
completion or the paused state, queue 2 begins executing again. The programming of the RESUME
bit in QACR2 determines which CCW is executed in queue 2. Refer to
Register
When simultaneous trigger events occur for queue 1 and queue 2, queue 1 begins execution and
the queue 2 status is changed to trigger pending.
