Abstract
A microcomputer includes an operation circuit for performing an operation using a reference voltage. A reference voltage input terminal receives the reference voltage from an external device. An output circuit outputs an output signal from the microcomputer to an external destination. The level of the output signal depends on the reference voltage input through the reference voltage input terminal.
