A controller capable of inhibiting storage of prescribed information associated with a control operation when the control operation cannot be normally performed, and resuming the storage immediately after the control operation has again become able to be normally performed. The controller includes determining means for determining whether or not the control operation can be normally performed on the basis of a power level of electrical power supplied to the controller, write-inhibiting means for setting a storage area for storing the information to a write-inhibited area in cases where it is determined that the control operation cannot be normally performed, and releasing means for releasing, as an interrupt process higher in priority than any other process, the write inhibited area in cases where it is determined after the setting of the storage area to the write-inhibited area that the control operation can be normally performed. |
