Daisy chain cascading devices

摘要

A technique for serially coupling devices in a daisy chain cascading arrangement. Devices are coupled in a daisy chain cascade arrangement such that outputs of a first device are coupled to inputs of a second device later in the daisy chain to accommodate the transfer of information, such as data, address and command information, and control signals to the second device from the first device. The devices coupled in the daisy chain comprise a serial input (SI) and a serial output (SO). Information is input to a device via the SI. The information is output from the device via the SO. The SO of an earlier device is the daisy chain cascade is coupled to the SI of a device later in the daisy chain cascade. Information input to the earlier device via the device's SI. is passed through the device and output from the device via the device's SO. The information is then transferred to the later device's s SI via the connection from the earlier device's SO and the later device' SI.
