This instruction
(1) Loads a new 7-bit address into the address counter (ACC).
(2) Sets the address counter (ACC) to point to the DD-RAM.
Once the “Set DD-RAM Address” instruction has been executed. The contents of the address counter
(ACC) will be automatically modified after each access of DD-RAM, as selected by the “Entry Mode Set”
instruction.

RS=1, /CS=0, /WR=0 to 1
This instruction writes 8-bit binary data (DB7 to DB0) into CG-RAM or DD-RAM.
To write into CG-RAM or DD-RAM is determined by the pervious specification of the CG-RAM or
DD-RAM address setting. After a write, the address is automatically incremented or decremented by 1
according to the entry mode. The entry mode also determines the display shift.
When data is written to the CG-RAM, the DB7, DB6 and DB5 bits are not displayed as characters.
