ABSTRACT:
A circuit for monitoring the program flow of a computerized or microprocessed system, includes a comparator for matching a uniquely assigned address for entering a given mode of operation, with an address presented by the system controller for entering the operating mode. If the addresses do not match, in response to the detected illegal mode entry attempt, a reset signal is generated for resetting the controller to reinitiate the programmed flow of operation.
