An apparatus comprises a number of sub-systems and a control interface operably coupled to sub-systems for routing data therebetween. A strobe generation function is operably coupled to the control interface and configured to generate a plurality of different strobe signals to differentiate between different intended receiving devices. Thus, different strobe signals may be multiplexed onto a single control interface link, based on a pulse width or voltage magnitude characteristics of the respective strobe signals. A strobe decoder function is operably coupled to the control interface and configured to decode a plurality of different strobe signals to differentiate between triggering sub-systems on receiving devices.
