Patent abstract
There is provided a resistor unit 115 for bypassing an output cell 107 of an interrupt request signal and an input cell 108 of an external interrupt factor, and the output cell 107 of the interrupt request signal is controlled to a high impedance when an internal power source is broken. Thus, an interrupt request signal sent from the external interrupt factor is given to a CPU when the internal power source is broken.
