摘要： A semiconductor device in which input terminals for external interrupts can be set as desired. A plurality of external input terminals can be specified as interrupt terminals which output an input signal to an external interrupt circuit via an interrupt terminal selector. A selection control circuit specifies whether a plurality of external input terminals are used as interrupt terminals. According to the selection control circuit, the interrupt terminal selector outputs to the external interrupt circuit an input signal entered from an external input terminal which is specified as an interrupt terminal out of the plurality of external input terminals.
