DL:
Interface data length control bit
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU. Hence, DL is a signal to select 8-bit or 4-bit bus
mode.
In 4-bit bus mode, it is required to transfer 4-bit data by two times.
N:
Display line number control bit
When N = "Low", it means 2-line display mode.
When N = "High", 4-line display mode is set.

Set DDRAM address to AC. This instruction makes DDRAM data available from MPU.
In 2-line display mode (N = 0) DDRAM address in the 1st line is from "00H" to "2FH", and DDRAM address in the
2nd line is from "40H to 6FH".
In 4-line display mode (N = 1), DDRAM address is from "00H to "17H" in the 1st line, from "20H" to "37H" in the
2nd line, from "40H" to "57H" in the 3rd line and from "60H" to "77H" in the 4th line.

This instruction shows whether S6A0079 is in internal operation or not. If the resultant BF is high, the internal
operation is in progress and you have to wait until BF to be low, which by then the next instruction can be
performed. In this instruction you can read the value of address counter.
