Abstract

According to an embodiment, an electronic device may comprise: a wired interface including a terminal; a detection circuit configured to detect a pulse signal having a frequency higher than a designated frequency received through the wired interface; a processor; and a memory storing instructions. According to one embodiment, the instructions, when collectively or individually executed by the processor, may cause the electronic device to receive a pulse signal from an external electronic device through the wired interface while communicating with the external electronic device through the wired interface. According to an embodiment, the instructions, when collectively or individually executed by the processor, may cause the electronic device to identify whether the frequency of the pulse signal remains higher than the designated frequency for a designated time, by using the detection circuit. According to an embodiment, the instructions, when collectively or individually executed by the processor, may cause the electronic device to apply a first signal of a first level output from the detection circuit to the processor or a charger included in the electronic device, upon confirming that the frequency of the pulse signal remains higher than the designated frequency for the designated time. According to an embodiment, the instructions, when executed collectively or individually by the processor, may cause the electronic device to reset the processor on the basis of application of the first signal to the processor or the charger.
