Figures 10-25 to 10-28 show the similar waveforms for the FIFO with output register and with output register enable
with RdEn. It should be noted that flags are asserted and de-asserted with similar timing to the FIFO without output
registers. However, it is only the data out 'Q' that is delayed by one clock cycle.
