<p>PROBLEM TO BE SOLVED: To solve the problem that it is erroneously judged that the control processing of a CPU for controlling a control function is normal when software processing is normally operated since a signal from the software processing different from a control signal is inputted to a monitoring function at the time of using the software processing for the error detection of the CPU, and that the control processing is compressed when the software processing is operated. SOLUTION: A control signal is directly monitored by branching a chip selection signal to be outputted from a CPU to a control function, and inputting it to a monitoring function.</p> |
