RESUMPTION PROCESSING SYSTEM

PURPOSE:To prevent the generation of an unnecessary loading by installing a resuming state judging register which is reset only when a power source is applied and judging whether or not it is resetting by the applying the power source, thereby loading a program to a memory only when the power source is applied. CONSTITUTION:A resuming state judging register 101 is reset only by a reset signal given by a reset circuit 107. In a case where resuming process is generated by some factor for resetting, the content of the resuming state judging register 101 is read out by a software in resuming process. When the resuming state judging register 101 is reset, it is judged as a reset due to the application of a power source, and a program is loaded, and specific data other than 0 is set to the resuming state judging register 101, and the process is executed. When specific data are set to the resuming process register 101 at the time of resuming processing, but not reset, it is judged as a reset caused by the factor of resetting other than the application of the power source, and the processing is executed.
