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.

For the streaming interface, only immediate mode is available. For the framing interface, both immediate and completion modes are available.
