Select the required option to add flow control to the core. User flow control (UFC) allows applications to send each other brief, high-priority messages through the Aurora 64B/66B channel. Native flow control (NFC) allows full-duplex receivers to regulate the rate of the data sent to them. Immediate mode allows idle codes to be inserted within data frames while completion mode only inserts idle codes between complete data frames.
Available options are:
• None
• UFC only
• Immediate NFC
• Completion NFC
• UFC + Immediate NFC
• UFC + Completion NFC
For the streaming interface, only immediate mode is available. For the framing interface, both immediate and completion modes are available.
Default: None
