<p>A resetting method of a system enables an EEPROM writing to be implemented to the end normally, and it is capable of avoiding runaway of the whole system, even if reset signal is taken in caused by power failure while the EEPROM is of the writing state. In the system which has a CPU (10), an EEPROM whole circuit (11), an oscillation circuit (8), and a reset control circuit (14), when a system reset occurs, detecting a writing operation of the EEPROM cell (1), in cases where the EEPROM cell (1) is implementing the writing operation, holding the reset of the EEPROM cell (1) until the writing operation of the EEPROM cell (1) is terminated, thus implementing the reset of at least the CPU (10). <IMAGE></p> |
