Empties data from the FIFO and sends the data to the recipient.
For DMA target-to-host FIFOs, the recipient is the host. For peer-to-peer writer FIFOs, the recipient is the peer-to-peer reader FIFO. You must enable the peer-to-peer stream when flushing a peer-to-peer writer FIFO. Otherwise, this node executes but does not flush the FIFO.
Reference to the FIFO.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error

If you use the Flush FIFO node when another FIFO flush is in progress, the two flushes merge.
