• ABLC (Arbitrator Line Change)
• Increment of the address pointer by one
[0, 1, 1, X, X, X, L1, L0]
This command selects a common line for arbitrator display, according to the settings of L1 and
L0. The table below shows the relationships between L1 and L0 and displayed common lines,
assuming that the display data at addresses 00 to 11 is character 1, the display data at
addresses 16 to 27 is character 2, the display data at addresses 32 to 43 is arbitrator 1, and the
display data at addresses 48 to 59 is arbitrator 2. Different common lines are displayed for 1/
16 duty and 1/9 duty.
After a low RESET is input, both L1 and L0 are set to "0".
Common lines displayed by the ABLC command are as follows:
When 1/16 duty is chosen
When 1/9 duty is chosen
Note: When 1/9 duty is chosen, characters 1 and 2 can be switched by changing the bank.
When display data or arbitrator blink data is input or the AINC or CHB command is executed,
the address pointer is incremented by one.
