Notes
1.
In the I
2
C-bus mode the DL bit is don't care. 8-bit mode is assumed.
In the I
2
C-bus mode a control byte is required when RS or R/W is changed; control byte: Co, RS, R/W, 0, 0, 0, 0, 0; command byte: DB7 to DB0.

No operation.
Clears entire display and sets DDRAM
address 0 in Address Counter.
Sets DDRAM address 0 in Address Counter
Also returns shifted display to original position
DDRAM contents remain unchanged.
Sets cursor move direction and specifies shift
of display. These operations are performed
during data write and read.
Sets entire display on/off (D), cursor on/off (C)
and blink of cursor position character (B).
Moves cursor and shifts display without
changing DDRAM contents.
Sets interface data length (DL), number of
display lines (N, M) and voltage generator
control (G).
Sets CGRAM address.
