<P>PROBLEM TO BE SOLVED: To distinguish between power-on by turning on an ignition and a reset due to reduction of power supply voltage in the middle of sequence processing. <P>SOLUTION: After the ignition is turned on, a number of processing in execution is stored in a storage means that retains memory contents even when power supply is lost, and processing is performed from the processing of number 0 in predetermined order. The processing number stored in the storage means is read out and processing is continued from that number when the power supply voltage falls below a predetermined voltage and then the power supply voltage is recovered and exceeds the predetermined voltage again. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
