WebA FWFT FIFO presents the data on the output as soon as it's available, so a low @empty signal means that the data on the output is valid. The meaning of @rd_en is different as well: For a "standard FIFO" it means "bring me data". On a FWFT FIFO it's something like "I just used the data, bring me the next data if you have it".
