A controller that operates using two different processors is provided. Each processor performs certain predetermined functions. A control processor is responsible for switching AC power distribution and control, while a message processors is responsible for messaging. A polling scheme and arbitration logic prevent data transfers relating to these two processors from interfering with each other. A configurable interface allows many different types of appliances to attach to the system, and a serial multimode interface further enhances the configurability of the system.

Control apparatus for use in a dwelling

The present invention uses a logic control to determine which of a plurality of processors receives priority, and generates WAIT signals for the non-selected processor. Further, user configurable pins exist that allow the user to determine the priority that the attached processor will obtain when simultaneous chip selects are transmitted.

Configurable multiport memory interface

The present invention provides a controller that operates using two different processors. Each processor performs certain predetermined functions. A control processor is responsible for switching AC power distribution and control, while a message processor is responsible for messaging. A polling scheme and arbitration logic prevent data transfers relating to these two processors from interfering with each other. A configurable interface allows many different types of appliances to attach to the system, and a serial multimode interface further enhances the configurability of the system.
