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
command ‘set DDRAM address’; look at the
description of the commands
