Reads the data element from a handshake item without acknowledging the transfer, meaning that the data remains in the handshake item.Use this node in addition to the Acknowledge Handshake node as an alternative to the Read Handshake node to read one element of data if you need to control when the node acknowledges the data transfer.
If ready for output is False during a given clock cycle, output valid returns False during that clock cycle.
Reference to a handshake item. You can wire a handshake control, handshake constant, or the reference out terminal of another Handshake node to reference in.
A Boolean that determines whether downstream nodes are ready for this node to return a new value. The default is True. Use a Feedback Node to wire the ready for input output of a downstream node to this input.
|True||Downstream nodes are ready for this node to return a new value.|
|False||Downstream nodes are not ready for this node to return a new value.|
The same handshake reference wired into this node.
Data transferred using the handshake item.
A Boolean that indicates whether this node has computed a result that downstream nodes can use. Wire this output to the input valid input of a downstream node to transfer data from the node to the downstream node.
|True||The node has computed a result that downstream nodes can use.|
|False||This node has not computed a result that downstream nodes can use. Any data output returns an undefined value. The undefined value returned by a data output may differ between simulation and hardware.|
