Abstract: To shift to an appropriate state according to operation of a reset switch.SOLUTION: An advantageous section display LED maintains a lit state since data regarding an advantageous section of an RWM is not initialized but is maintained if a reset switch is operated and a recoverable error state is canceled when the recoverable error state occurs in a state in which the advantageous section display LED is being lit. When the recoverable error state occurs in a state in which the advantageous section display LED is being lit, power is turned off. Then, when power is turned on in a state in which the reset switch is on, step S2710 of starting a program becomes "Yes" and control proceeds to step S2713 and an initialization range of the RWM is set. After that, control proceeds to initialization processing in step S2731, and initialization processing of the RWM is executed. In this case, since data regarding an advantageous section is initialized, the advantageous section display LED stays off after that.SELECTED DRAWING: Figure 354
