PURPOSE:To improve the processing capacity of a central processing unit and to shorten the processing time in general by providing a strobe signal generator circuit which operates by the decoder output of a reception circuit and generates the strobe signal to an interface circuit. CONSTITUTION:A strobe signal generator circuit 12, which operates by the decoder output of a reception circuit 1 and generates the strobe signal to an interface circuit 2, is provided between the reception circuit 1 for transmitting a decoder output relating to received data after data output and the interface circuit 2 for latching the data output of the circuit 1 and decoder output. After the circuit 1 transmits the decoder output, the circuit 2 outputs an interruption request to a central processing unit 3. Thus the unit 3 processes these outputs in the state where the data output and decoder output all appear. Accordingly it is unnecessary that software causes the unit 3 to be standby until the decoder output and data output and all appear, and therefore the processing capacity of the unit 3 can be improved by interrupting other signal processing. |
