7) Set CGRAM Address
8) Set DDRAM Address
9) Read Busy Flag & Address
Set DDRAM address to AC.
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
This instruction makes DDRAM data available from MPU.
When in 1-line display mode (N = 0), DDRAM address is from “00H” to “4FH”.
In 2-line display mode (N = 1), DDRAM address in the 1st line is from “00H” to “27H”, and DDRAM
address in the 2nd line is from “40H” to “67H”.
This instruction shows whether KS0070B is in internal operation or not. If the resultant BF is “1”, it means
the internal operation is in progress and you have to wait until BF is Low. Then the next instruction can
be performed. In this instruction you can also read the value of the address counter.
