PROBLEM TO BE SOLVED: To enhance security with respect to a microcomputer for game control.SOLUTION: On the basis of a generation of a prescribed event (e.g., an input of an IAT signal from an IAT 506a, an input of a time-out signal from a watchdog timer (WDT) 506b), whether to generate a first reset (e.g., a system reset) or to generate a second reset (e.g., a user reset) can be set. And, if the prescribed event is generated after processing at a power supply stop (e. g., a power interruption processing) is performed, a control state is caused to be restored to a state when the processing at a power supply stop is started on the basis of storage contents of storage means (e. g., a backup RAM). Also, a data storage area address is specified by referring to a value of a Q register.SELECTED DRAWING: Figure 12 |
