A communication system and method requiring only a single line for communication among integrated circuits (ICs). The system includes: a single communication line; plural ICs coupled to the single communication line; one of the ICs operating as a master IC; one of the ICs operating as a transmitting IC and one of the ICs operating as a receiving IC according to a designation by the master IC. The master IC transmits, on the single communication line, a reference signal having a reference signal width, CPW, to the other ICs. The master IC designates a first one of the ICs and a second one of the ICs as a chosen transmitting IC and a chosen receiving IC, respectively, for an imminent data-transmission operation, by transmitting signals of differing widths (relative to the reference signal width) over the single communication line. The ICs store the reference signal width and recognize their designation or not for the imminent data-transmission operation, respectively, by comparing the signals of differing widths against the reference signal width.
