D7 D6 D5 D4 D3 D2 D1 D0
Write binary 8-bit data to CGRAM, DDRAM or ICON RAM
The selection of RAM from DDRAM, CGRAM or ICON RAM, is set by the previous address set instruction
: DDRAM address set, CGRAM address set, ICON RAM address set. RAM set instruction can also determine
the AC direction to RAM.
After write operation, the address is automatically increased/decreased by 1, according to the entry mode.
l Read Data from CGRAM,DDRAM or ICON RAM
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

D7 D6 D5 D4 D3 D2 D1 D0
Read binary 8-bit data from DDRAM/CGRAM/ICON RAM
The selection of RAM is set by the previous address set instruction. If address set instruction of RAM is not
performed before this instruction, the data that read first is invalid, because the direction of AC is not
determined. If you read RAM data several times without RAM address set instruction before read operation,
you can get correct RAM data from the second, but the first data would be incorrect, because there is no time
margin to transfer RAM data.
※Read data must be “set address” before this instruction.
