Abstract
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.
