Abstract
An expanded memory interface is shown including an expanded memory controller for controlling a plurality of memory components for an application processor external to the interface. The application processor is connected to the expanded memory controller, which is in turn coupled to at least one status port for communication between the application processor and an external processor. At least one of the status ports are coupled to the external processor which uses such status port as an interrupt register for indicating status changes to the application processor.
