I. Read Busy Flag & Address

BF AC6 AC5 AC4 AC3 AC2 AC1 AC0

This instruction shows whether IC is in internal operation or not .

If BF is High, internal operation is in progress and shall wait until BF is to be

Low, which by then the next instruction can be performed. In this instruction

you and also read the value of the address counter.

J. Write data to RAM

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

D7 D6 D5 D4 D3 D2 D1 D0

Write binary 8-bit data to DDRAM/CGRAM.

The selection of RAM from DDRAM,and CGRAM,is set by the previous address set

instruction(DDRAM address set,CGRAM 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 the

entry mode.

K. Read data from 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.

The selection of RAM is set by the previous address set instruction.If the address set

instruction of RAM is not performed before this instruction, the data that has been read

first is invalid, as the direction of AC is not yet determined. If RAM data is read several

times without RAM address instructions set before read operation,the correct RAM data

can be obtained from the second. But the first data would be incorrect,as there is no time

margin to transfer RAM data.
