CONTROLLER FOR INTERFACE CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a controller for an interface circuit which can speedily allow access after data are initialized. SOLUTION: The interface circuit has a function of allowing and inhibiting access from an external device and the controller for the interface circuit is equipped with a command part which commands the operation. The command part is equipped with a control means which controls the interface circuit into an access-inhibited state right after the controller begins to be actuated and automatically allows the access a certain time later and an inhibiting means which can inhibit the operation for automatically controlling the interface circuit into the access permitted state at an external request before the interface circuit is automatically controlled into the access permitted state.
