2. Display on/off command (DISP command)

This command is used to select LCD panel display-on mode and display-off mode. Setting

DI = "0" enters display-off mode. At this time, the output voltage of all segments and common

output pins go to VDD level and the LCD panel goes out. Setting DI = "1" enters display-on

mode. At this time, the LCD panel restarts the status display before entering display-off

mode.

[DISP command format]

DISP

command

D8 D7 D6 D5 D4 D3 D2 D1

1 0 0 * 1 0 0 DI Display-off mode is set when DI = “0”

*: Don't care

Display-on mode is set when DI = “1”

3. Arbitrator Blink Control 1/5 command (ABBC 1/5 command)

This command is used to select the type of writing arbitrator blink data to the Arbitrator Blink

RAM (ABB RAM). This command is used along with the Character Blink on/off command

or with the Arbitrator Blink command, explained below.

Setting BC = "0" enables writing arbitrator blink data in 5-bit units using the CHB command.

Setting BC = "1" enables writing arbitrator blink data in 1 bit unit using the ABB command.

[ABBC 1/5 command format]

DISP

command

D8 D7 D6 D5 D4 D3 D2 D1

1 0 0 1 1 1 0 BC

BC = "0" enables writing in 5-bit unit.

BC = "1" enables writing in 1-bit unit.

4. Character Blink on/off command (CHB command)

This command is used to blink a character and arbitrator in 5-dot units. Blinking can be set

for each address pointer value. This command is used with the ABBC 1/5 command,

explained above.

If CB = "0" is set when the address pointer value is 00H to 0CH, "0" is written to Character Blink

RAM (CHB RAM), and the blinking of a character displayed in the segments corresponding

to the address pointer value stops. If CB = "1" is set, "1" is written to CHB RAM, and the

character displayed in the segments corresponding to the address pointer value starts

blinking.

If CB = "0" is set when the address pointer value is 10H to 1CH, "0" is written to the arbitrator

blink RAM (ABB RAM) and the blinking of the arbitrator displayed in the segments

corresponding to the address pointer value stops. If CB = "1" is set, "1" is written to the ABB

RAM, and the arbitrator displayed in the segments corresponding to the address pointer

value starts blinking.

Set the address pointer value by the LPA command before executing this command.

Transfer the LPA command, ABBC 1/5 command and CHB command as follows.
