Read Write I/O
Performs specific FPGA I/O operations on FPGA targets.
To begin using this node with I/O, click the Select I/O parameter and select an I/O from the list. Configure the channel properties of the selected I/O on the Item tab.
To create an I/O reference control, place an I/O Constant on the diagram, select an I/O in the constant, right-click the constant, and select Change to control. You can also create an I/O reference control by clicking on an I/O in this node, selecting Wire on diagram, right-clicking the I/O reference control terminal, and selecting Create control.
Inputs/Outputs

error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error

error out
Error information.
The node produces this output according to standard error behavior.

Select I/O
Data read from or written to the FPGA I/O you specify.
Click this parameter and select an I/O from the list. For I/Os that support read operation, this parameter is an indicator by default. For I/Os that do not support read operation, this parameter is a control by default. To change an I/O to a control or indicator, right-click the I/O in the node and select Change to write or Change to read.
To add more I/Os, drag the edge of the node up or down or right-click an I/O and select Insert element before. To remove an I/O, right-click the I/O and select Remove element.
