<P>PROBLEM TO BE SOLVED: To prevent occurrence of an abnormal operation caused by reset, in an electronic system in which a plurality of units are installed and respective units are reset to be linked with each other. <P>SOLUTION: A sub-microcomputer 2 outputs a close signal to a switch operating line S1, conducts a reset line R2 and a reset line R3, then outputs a reset signal to a reset line R4 and resets a main microcomputer 1. A reset signal is acquired from the main microcomputer 1 via the reset line R3 thereafter and the sub-microcomputer 2 itself is reset. In such a case, if the sub-microcomputer 2 is just under writing data into a storage device B22, the sub-microcomputer 2 outputs an open signal to the switch operating line S1, insulates the reset line R2 and the reset line R3 and then resets only the main microcomputer 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
