This instruction selects whether the cursor position increments or decrements after each DDRAM or CGRAM access

and determines the direction the information on the display shifts after each DDRAM write. The instruction also enables

CGRAM access). The DDRAM, CGRAM, and cursor position are not affected by this instruction.

If S=1, the information on the display shifts to the left by one character position after each DDRAM write.
