Cycle:
*A* Queue 30 is selected for read operations. It requires 4 clock cycles to switch queues.
*B* Reads are now enabled. A word from the previously selected queue will be read out.
*C* Another word from Present Queue (PQ) is read.
*D* Another word from PQ is read.
*E* Wd is read from Q30 of D1. This happens to be the last word of Q30, therefore OR goes HIGH to indicate that the data on the Qout is not valid (Q30 was read to empty).
*F* The last word of Q30 remains on the Qout bus, OR is HIGH, indicating that this word has been previously read.
*G* The last word of queue 30 remains on the Qout bus.
*H* The last word of queue 30 remains on the Qout bus.
*I* The next word, available from the newly selected queue, Q15 is now read out. This will occur regardless of REN, due to FWFT mode.
*J* A word, is read from Q15.
*K* The OR flag stays LOW to indicate that Q15 has additional words available for reading.
