Abstract
A method of detecting a communication mode is provided to rapidly detect which one of near field communication (NFC) protocols includes a communication frame pattern of data provided to a receiving device. The method includes receiving a communication frame pattern of data transmitted from an NFC initiator after synchronizing the communication frame pattern with a predetermined sampling clock. The detection of the communication mode may be done by analyzing a start pattern out of the communication frame pattern. Since a communication mode is rapidly detected and data is automatically received without performing an additional operation to set the communication mode, operation performance of a receiving device is improved.
