5. Arbitrator Blink command (ABB command)

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.
