摘要： An electronic device for performing communication with a master device via a serial communications bus and a method for performing assignment of an identifier on the electronic device are provided, wherein the master device is coupled to multiple slave devices via the serial communications bus, and the multiple slave devices include the electronic device. The electronic device includes a clock terminal, a data terminal, and a determination circuit coupled to the clock terminal and the data terminal, wherein the clock terminal and the data terminal receive a first signal and a second signal from the master device, respectively. The determination circuit determines whether a time point of pulling down the first signal is earlier than a time point of pulling down the second signal, in order to generate a determination result, wherein the assignment of the identifier of the electronic device is controlled according to the determination result.
