Note 1: Symbol "*" signifies an insignificant bit (disregard).
Note 2: Correct input value for "N" is predetermined for each model.
Restore display from shift and
* load address counter with DD
RAM address 00H.
Specify direction of cursor
movement and display shift
S mode. This operation takes
place after each data transfer
(read/write).
Specify activation of display (D)
B cursor (C) and blinking of
character at cursor position (B).
* Shift display or move cursor.
Set interface data length (DL),
* number of display line (N), and
character font (F).
Load the address counter with a
CG RAM address. Subsequent
data access is for CG RAM data.
Load the address counter with a
DD RAM address. Subsequent
data access is for DD RAM data.
Read Busy Flag (BF) and
contents of Address Counter
(AC).
Write data to CG RAM or DD
RAM.
Read data from CG RAM or DD
RAM.
