The queue operating mode selected for queue 1 determines what type of trigger event
causes the execution of each of the subqueues within queue 1. Similarly, the queue
operating mode for queue 2 determines the type of trigger event required to execute
each of the subqueues within queue 2.
The choice of single-scan or continuous-scan applies to the full queue, and is not ap-
plied to each subqueue. Once a subqueue is initiated, each CCW is executed sequen-
tially until the last CCW in the subqueue is executed and the pause state is entered.
Execution can only continue with the next CCW, which is the beginning of the next
subqueue. A subqueue cannot be executed a second time before the overall queue
execution has been completed.
Trigger events which occur during the execution of a subqueue are ignored, except
that the trigger overrun flag is set. When continuous-scan mode is selected, a trigger
event occurring after the completion of the last subqueue (after the queue completion
flag is set), causes execution to continue with the first subqueue, starting with the first
CCW in the queue.
