PURPOSE:To ensure effective connection among various peripheral devices of different transfer formats by switching a data line and the transfer format to each other. CONSTITUTION:When transfer of data is carried out with a slave IC 8, a data line 1 is selected by selectors 3 and 4 for transmission of eight clocks. While a data line 2 is selected for transmission of eight clock pulses when the data transfer is carried out with a slave IC 9. Then a signal A is operated by a clock generating circuit 5 via program processing for transmission of a 9th clock pulse. In such a way, data can be transferred between both IC 8 and IC 9 of different transfer formats.
