Abstract

PURPOSE: To judge whether or not a no-response state is caused by an instantaneous break or other external factors and to enable a proper abnormality process by referring o the state of the power source state holding means of a processor in which no response state is detected.
CONSTITUTION: If an instantaneous break occurs to a processor 11, information showing that the power source state holding means 13 of the processor 11 is powered on again is held. The control means 17 of a processor 15 refers to the state of the power source state holding means 13 of the processor 11 according to the no-response detection of the processor 11. While a startup process due to the no-presponse state which is caused by the instantaneous break is carried out, the information showing that the power source state holding means 13 is powered on again is held, so it is judged whether or not the no-response state is caused by an external factor and the abnormality process is carried out. Then the control means 17 of the processor 15 resets the state of the power source information holding means 13 of the processor 11 for a next instantaneous break after judging the cause of the no-response state. Consequently, it is easily judged whether or not the no-response state is caused by the external factor or an internal factor and the corresponding abnormality process is performed.
