Abstract

See full text

An electronic device has a first terminal for receiving power from a connected external device, a second terminal for obtaining information of the external device, and a GND terminal connected to the second terminal. The electronic device causes a resistance between the second terminal and the GND terminal to change, and determines a type of the external device based on a voltage of the first terminal after the resistance is caused to change.
