Abstract:
A method of obtaining status information from a peripheral device card installed within a peripheral device interface of a host device, wherein the peripheral device card includes a processor having a static random access memory (SRAM) attribute memory address space implemented therewithin, and wherein the SRAM attribute memory address space comprises a Card Information Structure (CIS) that is readable by the host device, the method comprising the steps of:transmitting an owner control signal from the peripheral device card to the host device, wherein the owner control signal provides a first indicium when the SRAM attribute memory address space is owned by the peripheral device card and a second indicium when the SRAM attribute memory address space is owned by the host device; and reading, via the host device, peripheral device card status information from the CIS when the owner control signal indicates host device ownership of the SRAM attribute memory address space.
