A first data selection circuit selects a data signal among a plurality of data signals from a plurality of circuits, a first direction selection circuit selects a direction control signal of the same circuit among a plurality of direction control signals from these circuits. A data holding circuit and a direction holding circuit respectively hold the selected data signal and direction control signal. A second data selection circuit selects a data signal from the first data selection circuit or the data holding circuit. A second direction selection circuit selects the direction control signal from the first direction selection circuit or the direction holding circuit.
