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). craftsman 2 panel door

"WebIn computing and in systems theory, FIFO is an acronym for first in, first out (the first in is the first out), a method for organizing the manipulation of a data structure (often, specifically a data buffer) where the oldest (first) entry, or "head" of the queue, is processed first.. Such processing is analogous to servicing people in a queue area on a first-come, first-served … " - Show-ahead synchronous fifo mode
