Clear Display Cursor at Home
Clears Display & Returns to Address 0. Returns Cursor to Address 0. Also returns the display being shifted to the original position. DDRAM contents remain unchanged. I/D: Set Cursor Moving Direction I/D=1: Increment I/D=0: Decrement S: Specify Shift of Display S=1: The display is shifted S=0: The display is not shifted
