Abstract
A resource port that provides a host processor the facility to request, share and access the resources of data communication equipment (DCE), including the memory and I/O registers of the DCE controller. In one embodiment the resource port has a controller request line to provide the host with a facility to request access to the controller resources, and an interface circuit to provide the facility to index all the resources of the DCE. The interface circuit compensates for any disparity between the widths of the controller address bus and the host processor address bus, and between the widths of the host processor data bus and the controller data bus.
