| Abstract | A hardware system comprises a master device and a slave device that are coupled by a signal line. A frequency generator in the master device places a selected frequency signal on the signal line. A frequency detector/comparator in the slave device, which is coupled to the signal line, determines whether the selected frequency signal on the signal line matches a predetermined frequency for the slave device. If the selected frequency signal matches the predetermined frequency, then a chip select node on the slave device is enabled, in order to permit a data exchange session between the master device and the slave device. |
