DEVICE PROVIDED WITH DATA CONFIRMATION MEANS

摘要

PURPOSE: To confirm data written in a storage device without using a flag bit. CONSTITUTION: A data confirming device is provided with an EEPROM memory 7. When data to be confirmed are continuously positioned at two 'neutral' locations (A2 and A3 of Φ0 and A3 and A4 of Φ2 ), the data written in this storage device are considered to be valid. This 'neutral' location is generated by preliminarily operated deletion necessary for the EEPROM memory for the writing of the data.
