Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
Set DDRAM address to AC.
This instruction makes DDRAM data available from MPU.
When 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".
In 3-line display mode (N3=1, N=1), DDRAM address in the 1st line is from “00H” to “OFH”, DDRAM in the
2nd line is from “10H” to “1FH”, and DDRAM in the 3rd line is from “20H” to “2FH”.

When BF = “High”, indicates that the internal operation is being processed. So during this time the next
instruction cannot be accepted.
The address Counter (AC) stores DDRAM/CGRAM addresses, transferred from IR.
After writing into (reading from) DDRAM/CGRAM, AC is automatically increased (decreased) by 1.
