A shade comprises a head rail that supports the lift cords for a shade panel. The control circuit, in response to a command signal received from outside of the semiconductor device, activates the first main word line at a first timing, and activates the second main word line at a second timing different from the first timing, the first main word line maintaining an activation state at said second timing. A port is provided in the housing exposing a portion of the first side of the shackle in the primary closed position.
