The contents of DDRAM are not changed. Sets cursor move direction and specifies display shift. These SH parameters are performed during data write and read. D=1: Entire display on B C=1: Cursor on B=1: Blinking cursor on Sets cursor moving and display shift control bit, and the direction without changing DDRAM data. DL: Interface data is 8/4 bits N: Number of lines is 2/1 F: Font size is 5x11/5x8 Set CGRAM address in address AC0 counter Set DDRAM address in address AC0 counter. Whether during internal operation or not can be known AC0 by reading BF. The contents of address counter can also be read. Write data into internal RAM D0 (DDRAM/CGRAM).
