プ装置。 an internal counter that integrates measured values; a DC/DC converter to which a source voltage is input and converts the source voltage to create a smaller circuit voltage and output it; a large-capacity capacitor that holds the source voltage; a comparator that compares a voltage related to the source voltage with a set voltage smaller than the source voltage and outputs an error signal; a delay circuit that outputs a reset signal delayed by a predetermined time with respect to the error signal; a microprocessor that outputs a storage command to store integrated data by receiving a non-maskable interrupt signal that causes a level change almost simultaneously with the error signal; and outputs a read command to read the stored data in response to the reset signal; EEP in which the integrated value of the internal counter is stored via a data bus based on a command;
ROM, and the EE in relation to the reset signal.
An integrated value backup device characterized in that an integrated value stored in a PROM is returned to the internal counter.
