Abstract
A plurality of external input information are added to a selecting circuit. The output of the selecting circuit is fed back as one of the external input information to the selecting circuit. The input signal groups are decoded, and are produced as control signals to specify the external input information in synchronism with clock signals. When the input select signal groups have the non-selection mode, the output that is fed back is necessarily selected.
