COMMUNICATION DEVICE AND COMMUNICATION SYSTEM

Abstract: a communication device includes a signal generation circuit, a communication interface, and a processing circuit. the signal generation circuit is configured to, based on a first control signal including a first logic level and a second logic level, generate a second control signal including the first logic level and the second logic level. the communication interface is coupled to a communication bus, and is configured to receive an identifier setting command. the processing circuit is configured to set the identifier when the first control signal is at the first logic level and the identifier has not yet been set. the signal generation circuit is configured to: set the second control signal to the second logic level when the processing circuit has not yet set the identifier; and set the second control signal to the first logic level after the processing circuit sets the identifier.
