<P>PROBLEM TO BE SOLVED: To prevent instability in operation of an electronic circuit even when an unexpected reset process occurs in a sub-CPU. <P>SOLUTION: When there is no reset signal from a power supply ICB12, a CPUA21 outputs a reset signal to a CPUB22 on the basis of a control signal output from the CPUB 22 and indicating whether there is a communication abnormality. When there is a reset signal from the power supply ICB12, the CPUA21 outputs the reset signal to the CPUB22, and stops output control of the reset signal based on the control signal during a period in which the CPUB22 performs a reset process based on the reset signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
