PURPOSE:To reduce the load of a program for transmission of data by producing a strobe signal based on a signal related to the transmission of data. CONSTITUTION:The transmission data DATA is put on a data bus and written to a data buffer 31 with the timing where a decoding signal DEC is delivered from a decoder 32. Then a counter 34 is put under an enable state via a flip-flop 33 with the rise timing of the signal DEC. Thus the counter 34 starts its counting action. The output of a flip-flop 35 is inverted (raised) by the output of a carry signal CARY, and a strobe signal STROBE is delivered. Then the output of the signal STROBE is stopped with the second signal CARY. The DATA set at the buffer 31 is transmitted with the timing where the signal STROBE is delivered. |
