Display ON/OFF control
Function: Sets both display and cursor ON/OFF, and
extended register access.
Display ON/OFF is specified by setting D.
D
= 0
: Display ON
D
= 1
: Display ON
Character blink ON/OFF at the cursor position is
specified by setting B. However, when the cursor is
OFF, this bit is invalidated.
B
= 0
: Cursor blink OFF
B
= 1
: Cursor blink ON
Cursor ON/OFF is specified by setting C.
C
= 0
: No display of cursor
C
= 1
: Display of cursor
Extended register access is specified by setting RE.
RE
= 0
: Extended register OFF
RE
= 1
: Extended register ON
The relation between C/B register and cursor display
is shown in the following table.
C

Example of cursor display
(C, B) = (0, 0)
(1, 0)
(1, 1)
f Blink
The cursor display position is indicated by the address
counter. Accordingly, when moving the cursor, change
the address counter value by the RAM address set
command or the auto increment by the RAM data write
command.
To display the under-bar cursor when character data
(CGRAM) at the cursor position, the position
corresponding to the cursor position will be displayed in
black-and-white reverse form.
If the address counter is set to the symbol register
position at (C, B) = (1, 1), symbols can be caused to blink
selectively (every 5 dots because symbols correspond to
characters).
Power save
Function: Controls the oscillating circuit and sets and
resets the power save mode and the sleep
mode.
Power save mode ON/OFF is specified by setting PS.
PS
= 0
: Power save OFF (reset)
PS
= 1
: Power save ON (set)
Oscillating circuit ON/OFF is specified by setting O.
O
= 0
: Oscillating circuit OFF
(stop of oscillation)
O
= 1
: Oscillating circuit ON
(start of oscillation)
