ABBC1/5
This command is used to start writing arbitrator blink data to ABB RAM in 1-dot unit. This
command is used with the ABB 1/5 command described above.
After setting AB = "1", setting the C/D pin from "1" to "0" enables writing arbitrator blink data
to ABB RAM in 1-dot unit. After arbitrator blink data is transferred, the address pointer is
automatically incremented by 1, and arbitrator blink data can be transferred continuously.
Set the address pointer value by the LPA command before executing this command. Transfer
the ABBC 1/5 command, ABB command and arbitrator blink data as follows.

Specify the address pointer value.
(Example: Set the address pointer to 10H.)
Set BC = “1” to enable writing in 1-dot unit.
Set AB = “1” to start writing in 1-dot unit.
Arbitrator blink data is written to ABB RAM address 10H,
and the arbitrator specified in segments 1 to 5 starts blinking.
After this command is executed, the address pointer value
becomes 11H.
Arbitrator blink data is written to ABB RAM address 11H,
and the arbitrator specified in segments 6 to 10 starts blinking.
After this command is executed, the address pointer value
becomes 12H.
Arbitrator blink data is written to ABB RAM address 1BH,
and the arbitrator specified in segments 59 to 60 starts
blinking.
After this command is executed, the address pointer value
becomes 1CH.
