Figure 10-33 show the behavior of non-pipelined FIFO_DC or FIFO_DC without output registers. When we pipeline
the registers, the output data is delayed by one clock cycle. There is an extra option for the output registers to be
enabled by the RdEn signal.
Figures 10-34 to 10-37 show the similar waveforms for the FIFO_DC with output register and without output regis-
ter enable with RdEn. Note that flags are asserted and de-asserted with similar timing to the FIFO_DC without out-
put registers. However, it is only the data out 'Q' that is delayed by one clock cycle.
