The "ripple down" delay is only noticeable for the first word

be no delay evident for subsequent words written to the

The first free location created by reading from a full depth is the WCLK period. Note that extra cycles should be added

FIFO to write a word to fill it.  
The Transfer Clock line should be tied to either WCLK or
