Case 3: Reading From a Full FIFO
Clock Event 2: Write Operation, and Assertion of FULL Signal
The FULL signal pin is asserted when the FIFO is full.
•
•
•
If the FIFO is full and a read followed by a write is performed, the FULL signal remains
asserted.
Clock Event 3: Write Operation and Assertion of Write Error Signal
The write error signal pin is asserted when data going into the FIFO is not written because
the FIFO is in a FULL state.
•
•
•
Clock Event 4: Write Operation and Deassertion of Write Error Signal
WRERR) is deasserted when a user stops trying to write into a full FIFO.
•
•
The write error signal is asserted/deasserted at every write-clock positive edge. As long as
both the write enable and FULL signals are true, write error will remain asserted.
