Figure 9-40. FIFO with Output Registers, End of Data Read Cycle
And finally, if you select the option enable output register with RdEn, it still delays the data out by one clock cycle
(as compared to the non-pipelined FIFO), and the RdEn should be high also during that clock cycle, otherwise the
data takes an extra clock cycle when the RdEn goes true.
