PROBLEM TO BE SOLVED: To improve the security relating to a microcomputer for game control.SOLUTION: It is possible to set a first reset (for example, system reset) to occur or a second reset (for example, user reset) to occur, on the basis of the occurrence of a prescribed event(for example, an input of an IAT signal from an IAT 506a, an input of a time-out signal from a watchdog timer (WDT) 506b). In addition, when a prescribed event occurs during the execution of prescribed processing (for example, loop processing of main processing, timer interruption processing), the stored contents of memory means (for example, a backup RAM) is initialized. Moreover, when a prescribed event occurs after the execution of power supply stop processing (for example, power interruption processing), a control state is restored to a state at the start of the power supply stop processing on the basis of the stored contents of the memory means (for example, a backup RAM).SELECTED DRAWING: Figure 12 |
