Abstract
A transfer circuitincludes two sets of an input circuitA and an output circuitB, which allows bidirectional transfer. The input circuitA decomposes external input data signals DIA and DIA to signals on lines Lto Lin synchronism with a clock signal CLK in order to reduce the frequency thereof. The output circuitB composes the decomposed signals in synchronism with the clock signal CLK to regenerate the original signals and output them as external output data signals DOB and DOB. Signals on either the lines Lto Lor Lto Lare selected by a multiplexerto provide to a main body circuit.
