WebJun 21, 2024 · The FIFO works fine. I use it in "Show-ahead synchronous FIFO mode”. - The first time the power is on, the FIFO is empty, the output q[11...0] sends a "0" when the uControler reads it. Right. - Then it receives true data.-When the FIFO has been read for 16 times (depth of the FIFO), the data shown in q[11...0] is not "0" (the FIFO is empty).
