the aborted queue 2 CCW entry. The RESUME bit in QACR2 allows the software
to select where queue 2 begins after suspension. By choosing to re-execute all of
the suspended queue 2 queue and sub-queue CCWs, all of the samples are guar-
anteed to have been taken during the same scan pass. However, a high trigger
event rate for queue 1 can prohibit the completion of queue 2. If this occurs, the
software may choose to begin execution of queue 2 with the aborted CCW entry.
