no operation
sets interface Data Length (DL), number of display
lines (M), single line/MUX 1 : 9 (SL) and extended
instruction set control (H)
reads the Busy Flag (BF) indicating internal
operating is being performed and reads Address
counter (A
reads data from CGRAM or DDRAM
writes data from CGRAM or DDRAM
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 (I/D) and specifies shift
of display (S); 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); D = 0 (display
off) puts chip into the Power-down mode
moves cursor or shifts display (S/C) to right or left
(R/L) without changing DDRAM contents
sets CGRAM address; bit DB6 is to be set by the
