Abstract
In one embodiment of the present invention, a two-register interface is provided by a first electronic device to allow access to memory within the electronic device by external electronic devices. The two-register interface is mapped from the memory of an accessing, second electronic device. READ and WRITE accesses are transmitted from the accessing, second electronic device to the two-register interface through a communications medium. A first register of the two-register interface directs access to a particular memory location, and the second register of the two-register interface provides a portal for both READ and WRITE access to the particular memory location.
