PROBLEM TO BE SOLVED: To write normal initial value data to an EEPROM which stores set values for setting a system when a power source is turned no again even if the writing of the initial value data to the EEPROM is interrupted. SOLUTION: This data writing system which writes the initial value data of the system reads ID data out of the EEPROM when power is turned on, collates the read ID data with predetermined data for identifying the system, and initializes the EEPROM and writes the previously set initial value data and then the ID data to the EEPROM when the comparison result indicates discrepancy. |
