Clears all the displayed digits of the LCD and
sets the DDRAM address 0 in the address
counter. The arbitrator data is cleared.
Sets the DDRAM address 0 in the address
counter and shifts the display back to the
original. The content of the DDRAM
remains unchanged.
Determines the direction of movement of
the cursor and whether or not to shift the
display. This instruction is executed when
data is written or read.
Sets LCD display ON/OFF (D), cursor
ON/OFF or cursor-position character
blinking ON/OFF.
Moves the cursor or shifts the display
without changing the content of the DDRAM.
Sets the interface data length (DL), the
number of display lines (N) or the type of
character font (F).
Sets on CGRAM address. After that,
CGRAM data is transferred to and from
the CPU.
Sets a DDRAM address. After that DDRAM
data is transferred to and from the CPU.
Reads the Busy Flag (indicating that the
ML9044 is operating) and the content of
the address counter.
Writes data in DDRAM, ABRAM or CGRAM.
Reads data from DDRAM, ABRAM or CGRAM.
Writes data to control the contrast of the LCD.
Reads data to control the contrast of the LCD.
