Abstract
Time-sequenced multi-device address assignment is provided. In this regard, an electronic device includes a plurality of client devices that are daisy-chained to a host interface port in a host controller by a reset line. The host controller is configured to assert the reset line to reset the daisy-chained client devices and then sequentially de-assert the reset line for the daisy-chained client devices according to a determined time sequence. Accordingly, the host controller assigns a unique client device address to each of the client devices when the reset line is de-asserted for the client device. By daisy-chaining the client devices via the reset line and sequentially assigning the unique client device addresses based on the determined time sequence, it is possible to assign the unique client device addresses from a single host interface port, thus reducing design complexity, footprint, and power consumption in the electronic device.
