| http://www.w3.org/ns/prov#value | - The supply voltage monitor unit 230 shown in FIG. 8 is a circuit for issuing a low level to voltage abnormality signal EV when the supply voltage becomes lower than a specified voltage VL. The supply voltage monitor unit 230 includes resistive elements R1, R2, R3, reference NMOS transistor TN, and comparator CP having plus input IP and minus input IM. Between the supply voltage VD and ground VS, t
