    摘要： The present invention uses a logic control to determine which of a plurality of processors receives priority, and generates WAIT signals for the non-selected processor. Further, user configurable pins exist that allow the user to determine the priority that the attached processor will obtain when simultaneous chip selects are transmitted.
