Reading a status word from the Status FIFO is mechanized by a single AXI4-Stream data beat. An example of reading five status
entries from the MM2S Status FIFO is shown in the following figure. In this scenario,
the Status FIFO is synchronous to the memory-mapped address and data channel clock. The
example illustrates that a status word is considered read from the Status FIFO only when
the tvalid and tready
handshake signals are both asserted at the rising edge of the synchronizing clock.
