• DISP (Display on/off)
[1,0,0,X,1,0,0,1/0]
Command used to control display-on and display-off of the LCD panel.
When D0 is "1", the display of the LCD panel goes on, and When D0 is "0", it goes off.
When the display is off, the V_DD level voltage is output on all of pins of both the segment
drivers and the common drivers.
D0 is set to "0" after inputting Reset.
• ABBC 1/5 (Arbitrator Blink Control 1/5 dot)
[1,0,0,1,1,1,0,1/0]
Command used to do switching between arbitrator’s blinking in a 1-dot unit and or in
a 5-dot unit.
When D0 is "1", arbitrator’s blinking comes in the 1 dot unit mode.
When D0 is "0", it comes in the 5-dot unit mode.
D0="0" is set after inputting Reset.
Note: 1-dot unit blink setting Æ See ABB.
5-dot unit blink setting Æ See CHB.
• ABB (Arbitrator Blink)
[1,0,0,0,1,1,0,1/0]
Command used to control on/off of blinking, which is valid only when arbitrator’s
blinking is set in the 1-dot unit mode.
Data , which are entered via SI pin after setting D0="1", are taken as arbitrator blink data
(1-dot unit).
Input blink data correspond to each of arbitrator’s dots. When "1", blinking is on, and
when "0", blinking is off.
Note that the arbitrator, which arbitrator-on is not specified, is not able to blink, though
blink-setting is available. Dummy data must be entered into the arbitrator blink data D5
thru D7.
It is impossible to write data in addresses 00 through 31.
D0="0" is set after inputting Reset.
Note: If blink is set in the 5-dot unit mode, ABB command setting (D0="1" or "0") is
available, but blink-on/off setting via input of display data is impossible.
• AINC (Address Increment)
[1,0,0,X,1,X,1,X]
Command used to increment the value of the address pointer by 1.
The pointer is increment by 1 each time this command is executed. The operation set by
LOT command is given to the address before being increased by 1 each time this
command is execution.
