Specify address pointer value
(Example: Set address pointer value to 10H.)
Arbitrator display data is written to AB RAM address 10H,
and the specified arbitrator of segments 1 to 5 can be
displayed.
After this data transfer is executed, the address pointer value
becomes 11H.
Arbitrator display data is written to AB RAM address 11H,
and the specified arbitrator of segments 6 to 10 can be
displayed.
After this data transfer is executed, the address pointer value
becomes 12H.
Arbitrator display data is written to AB RAM address 12H,
and the specified arbitrator of segments 11 to 15 can be
displayed.
After this data transfer is executed, the address pointer value
becomes 13H.
Arbitrator display data is written to AB RAM address 1BH,
and the specified arbitrator of segments 59 to 60 can be
displayed.
After this data transfer is executed, the address pointer value
becomes 1CH.
Arbitrator display data is written to AB RAM address 1CH,
and the specified arbitrator of segments 61 to 65 can be
displayed.
After this data transfer is executed, the address pointer value
becomes 1DH.
AB RAM address is only 10H to 1CH. The address
pointer value becomes 1DH. However, this
arbitrator display data is ignored.
