If BQ2 was assigned to the CCW that queue 1 is currently
working on, then that conversion is completed before BQ2
takes effect.
Each time a CCW is read for queue 1, the CCW location is compared with the current value
of the BQ2 pointer to detect a possible end-of-queue condition. For example, if BQ2 is
changed to CCW3 while queue 1 is converting CCW2, queue 1 is terminated after the
conversion is completed. However, if BQ2 is changed to CCW1 while queue 1 is
converting CCW2, the QADC64E would not recognize a BQ2 end-of-queue condition until
queue 1 execution reached CCW1 again, presumably on the next pass through the queue.
