Abstract
In a Near Field Communications (NFC) link, the data link turn-around time is adjusted to optimize battery use while maximizing the data throughput. A receiving device immediately transmits any pending high priority control or data messages in its own queue in response to a message from the sending device, subject to the flow control status of the sending device. The value of the delay time before sending a SYMM primitive is selected in accordance with the types of link frames recently received.
