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