Clear all display, and sets DDRAM
address at 00H
Set DDRAM address at 00H. Also
returns the display being shifted to the
original position. DDRAM contents
remain unchanged.
Sets the cursor direction and specifies
display shift. These operations are
performed during the writing/reading
of data.
Sets all display on/off (D)
Cursor on/off (C).
Cursor blinks on character position (B)
Shifts display or cursor, also keeps
DDRAM contents.
Sets data length (in parallel data
transfer) and number of line.
Sets address of CGRAM. After which
CGRAM data is transferred.
Sets DDRAM address, after which
DDRAM data is transferred.
