CHB

command

Specify address pointer value

(Example: Set address pointer value to 10H.)

Set BC = “0” to enable writing in 5-dot units.

CB value is written to ABB RAM address 10H, and the

blinking of arbitrator displayed in segments 1 to 5 is set.

After this command is executed, the address pointer value

becomes 11H.

CB value is written to ABB RAM address 11H, and the

blinking of arbitrator displayed in segments 6 to 10 is set.

After this command is executed, the address pointer value

becomes 12H.

CB value is written to ABB RAM address 1BH, and the

blinking of arbitrator displayed in segments 56 to 60 is set.

After this command is executed, the address pointer value

becomes 1CH.

CB value is written to ABB RAM address 1CH and the

blinking of arbitrator displayed in segments 61 to 65 is set.

After this command is executed, the address pointer value

becomes 1DH.

ABB RAM address is only 10H to 1CH. The address

pointer value becomes 1DH. However, this CHB

command is ignored.
