<p>PURPOSE:To perform the best postprocessing in accordance with the cause of the on-off operation of a power source by providing a processing program which corresponds to the cause and selecting the processing program by a flag set when the processing program is provided. CONSTITUTION:When a power source is put to work with a key, a key-on signal is generated and inputted to an FF12, a DC power source rises, and a DC power signal generating circuit 12 generates a power ready signal. Further, once respective parts are initialized by an initialization circuit 11, its end signal is inputted to an FF12 while the key-on signal is generated, thereby setting a deciding flag. After the deciding flag is set through hardware as mentioned above, respective stopping, IPL and restarting operations, etc., are processed by microprograms and the processing operations by the programs end, resetting the deciding flag of the FF12. When the power source is turned on, the stopping IPL and restarting operations are performed selectively in accordance with whether the deciding flag is set or not. The operations when the power source is turned off are omitted.</p> |
