Disclosed is a method in which slaves are cascaded on a bus, and cascading slave-to-slave communication is used to prioritize (or sequence) the software slave ID programming, enabling users to uniquely identify identical components in a circuit. In one embodiment, the first slave in the cascade stalls the programming of other slaves until the first slave's programming is complete. Once completed, the first slave then enables programming of the second slave, and so on. This embodiment allows multiple placements of identical slaves on the bus, and provides a method to uniquely identify and control each slave by using cascading software slave ID programming. In another embodiment, a structure with a similar effect may be created by lack of enablement (instead of disablement), wherein initially only the first slave is enabled, and subsequent slaves are not initially enabled. Additionally, the present disclosure is compatible with the MIPI RFFE standard interface.
