Write FIFO (Clock-Driven Logic)

Reference to the FIFO.

Data element to write 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.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Boolean value that describes whether the next data element has arrived for processing. Wire the output valid output of an upstream node to this input to transfer data from the upstream node to this node.

Boolean value that indicates whether this node is ready to accept new input data.

Use Feedback Node to wire this output to the ready for output output of an upstream node.

Note

If this output returns False during a given cycle, this node discards any data that other nodes send to this node during the following cycle. This node discards the data even if input valid is True during the following cycle.
