摘要：
A serial I/O incorporated semiconductor device comprises a transmitting unit 4 including a transmission channel selection register 14 for selecting a transmitting pin to output transmit data and a receiving unit 5 including a receiving channel detection circuit 26 for detecting receiving pins that have received data; a receiving channel flag 27 set to have a predetermined value by the receiving channel detection circuit; a plural channels reception detection circuit 28 for detecting that received data is entered to a plurality of receiving pins; and a plural channels receiving flag 29 set to have a predetermined value by the plural channels reception detection circuit 28 detecting received data has been entered to the plurality of receiving pins; wherein when any one of the flags 23, 25, and 29 is set to a predetermined value, the receiving unit supplies the value to a CPU as a reception interrupt signal.
