FIELD OF THE DISCLOSURE

This disclosure generally relates to information handling systems, and more particularly relates to handling in-band interrupts on inactive I3C channels in an information handling system.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software resources that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

SUMMARY

A multiplexor for an Improved Inter-Integrated Circuit (I3C) network may include a switch, a snooper, and an I3C slave module coupled to an I3C master interface. The switch may selectably couple I3C busses to the I3C master interface. Each I3C bus may include I3C slave interfaces. The selected I3C bus may be the active bus, and the non-selected I3C busses may be inactive buses. The snooper may detect In-Band Interrupts (IBIs) from the I3C slave interfaces coupled to the inactive buses. When the snooper receives a first IBI on an inactive bus, the snooper may provide an indication. The I3C slave module may provide a second IBI to the I3C master interface in response to the indication.
