ABSTRACT:
In a system using a processor or microprocessor for executing a predetermined initial processing and than a main processing based on a predetermined program when a reset signal is inputted, a start processing system after cutoff of a power source of the present invention includes a read-only memory (ROM) for storing a program for executing the initial processing, a program for executing the main processing and for storing initial data, a random access memory (RAM) for storing and reading data when the main processing is executed and a backup device for keeping driving of the RAM for a predetermined time after cutoff of the power source. The program for executing the initial start program includes a program for comparing data stored at a predetermined address area of the RAM memory with data stored at a predetermined address area of the ROM and for moving the initial data stored in the ROM to the RAM when the result of comparison of the data proves different.
