QADC64E Legacy Mode Operation
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.
13.3.8
The status registers contains information about the state of each queue and the current A/D conversion.
Except for the four flag bits (CF1, PF1, CF2, and PF2) and the two trigger overrun bits (TOR1 and TOR2),

Status Registers (QASR0 and QASR1)
If BQ2 was assigned to the CCW that queue 1 is currently working on, then
that conversion is completed before BQ2 takes effect.
