<p>PROBLEM TO BE SOLVED: To make it possible to use a signal from a signal source for generating a signal for restoring a microcomputer(MC) from a stand-by state to a normal state as an interruption signal of low priority in the normal state of the MC. SOLUTION: The MC 1 has a non-maskable interrupt(NMI) input terminal a normal interrupt input terminal TNT and an output terminal B for a signal indicating a stand-by state. A signal from the signal generation source 2 to the MC 1 is switched by a changeover switch 4 so as to be inputted to the terminal NMI when the MC 1 is a stand-by state and inputted to the terminal INT when the MC 1 is a normal operation state.</p> |
