    摘要： Several systems and methods of chip select are described. In one such method, a device maintains two identifiers, (ID_a and ID_m). When the device receives a command, it examines the values of ID_a and ID_m relative to a third reference identifier (ID_s). If either ID_a or ID_m is equivalent to ID_s, the device executes the command, otherwise, the device ignores the command. By using two different identification methods, a system has options in choosing to activate devices, being able to selectively switch between selecting multiple devices and single devices in a quick manner. In another such method, a device may have a persistent area that stores identification information such as an ID_a. Thus, system functionality may remain independent from any defect/marginality associated with the physical or logical components required for initial ID_a assignment of all devices in the system.

    摘要： A method includes receiving an enumeration message via a host interface of a device that is operatively coupled to a host device and to one or more other devices. The method includes identifying the enumeration message as a command originated by the host device or as a response message from one of the other devices. In response to identifying the enumeration message as a command, an enumeration response message is sent to the host device. The enumeration response message indicates a distinctive device identifier value. The method also includes, in response to identifying the enumeration message as a response message from one of the other devices, reading from the response message an identifier value used by such other device and at least temporarily storing this identifier value at the device to enable the device to select the distinctive device identifier value.

    摘要： A serial communication branching device and a serial communication system are provided. The serial communication branching device, which branches a plurality of slaves connected to the master by a daisy chain into a plurality of paths, is equipped with a first communication circuit that carries out communication with the master connected to a preceding stage side, a plurality of second communication circuits that carry out communication with the slaves of the paths connected to a subsequent stage side, and a path selection circuit disposed between the first communication circuit and the second communication circuits. In the case that a slave connected on the subsequent stage side transmits a reply signal to the master responsive to a transmission signal transmitted from the master, the path selection circuit selects a path of the slave that transmits the reply signal, and outputs the reply signal from the selected path to the master.

    摘要： A communication system with train bus architecture is described. The communication system with the train bus architecture comprises a coupling device for transmitting a first instruction packet string having instruction packets via first path; the controlled module for receiving the first instruction packet string via first path, wherein the controlled module selects one instruction packet from the instruction packets, replaces the selected instruction packet by first response packet for forming second instruction packet string, and processes the selected instruction packet to generate a second response packet; and a terminal device for receiving the second instruction packet string via the first path, and for transmitting the second instruction packet string back to the coupling device via the at least one controlled module along a second path from the terminal device to the coupling device wherein the first path is connected to the second path to form train bus architecture.
