Abstract: PROBLEM TO BE SOLVED: To reduce material quantity of a microprocessor and a sending and receiving port by sending information that corresponds to a read instruction from a port that is indicated by port information stored in a register. SOLUTION: A control circuit 944 receives a read instruction from a bus 976 and when an address belongs to the inside of a serial interface 802, it writes the number of a receiving circuit which outputs the read instruction in a 1st port register 946 and outputs the read instruction. Then, data is transferred to a sending circuit through the bus 976 and a mask signal is outputted to a signal line 972 according to the stored number. Also, when it belongs to the outside of the address serial interface 802, the circuit 944 writes the number of a receiving circuit that outputs a read instruction in a 2nd port register 948 and outputs the read instruction. And it transfers data to the sending circuit through the bus 976 and outputs a mask signal to the line 972 through the stored number.
