Figures 9-33 to 9-36 show the behavior of non-pipelined FIFO or FIFO without output registers. When we pipeline
the registers, the output data is delayed by one clock cycle. There is an extra option of output registers being
enabled by RdEn signal.
Figures 9-37 to 9-40 show the similar waveforms for the FIFO with output register and without output register
enable with RdEn. It should be noted that flags are asserted and de-asserted with similar timing to the FIFO with-
out output registers. However it is only the data out 'Q' that gets delayed by one clock cycle.
