Abstract: Assigning addresses to legacy sharing at least one signal line with a plurality of client devices. Each of the devices includes a number of I/O pins selected ones of which are connected to the at least one signal line and each client device includes a first and a second initialization pin. In the described embodiment, all but a first one of the plurality of client devices are connected to one another in a daisy chain arrangement by way of the first and the second initialization pin separate from the signal line. A first client device has a first initialization pin that is independently held at a first logic level and a second initialization pin that is connected to the daisy chain arrangement. The first one of the client devices is initialized and, in turn, triggers initialization of the daisy chained client devices. The legacy device is initialized separately from the client devices.
