Arbitrator RAM (ABRAM)
The arbitrator RAM(ABRAM) stores arbitrator display data.
The ABRAM address is set at the ADC with the relationship illustrated below. Its valid address
area is 00 to 23 (00H to 17H).
Although an address exceeding 23 (17H) can be set or the address already set may exceed it due
to automatic increment or decrement processing, any address out of the valid address area is
ignored.
The cursor or blink is also displayed even when a CGRAM or ABRAM address is set in the ADC.
Therefore, the cursor or blink display should be inhibited while the ADC is hoding a CGRAM
or ABRAM address.

Sn = ABRAM address (0 to 23)
The arbitrator RAM can store a maximum of 120 dots of the arbitrator Display–ON data in units
of 5 dots.
The arbitrator display is not shifted by any instructions and has the following relationship with
the LCD display positions:.
