V2.0
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".
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU. So to speak, DL is a signal to select
8-bit or 4-bit bus mode.
When 4-bit bus mode, it needs to transfer 4-bit data by two times.
When N = "Low", it means 1-line display mode.
When N = "High", 2-line display mode is set.
When F = "Low", it means 5 x 8 dots format display mode
When F = "High", 5 x11 dots format display mode.
