Abstract
A device, in which circuit size is small and operation is stable, comprises a plurality of serially connected unit registers (shift registers) in which transfer is controlled by any of three or more clock signals each having a different phase, and a setting signal which determines shift direction; and a selection circuit (switch array) which can select at least one clock signal from the three or more clock signals in accordance with the setting signal; wherein the unit registers are put in a reset state by one clock signal selected by the selection circuit, corresponding to each of the unit registers
