Returns the oldest element of a FIFO without removing the oldest element.
Peek FIFO is supported on all local, DMA host-to-target, and peer-to-peer reader FIFOs, regardless of the implementation type.
Reference to the FIFO.
Amount of time, in clock ticks, that the node waits before timing out.
Default: 0
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
Reference to the FIFO.
Oldest data element in the FIFO.
If the FIFO is empty, data returns an undefined element.
Error information.
