$" 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. 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.  
$" N : Display line number control bit  
When N = "Low", it means 1-line display mode.  
When N = "High", 2-line display mode is set.  
$" F : Display font type control bit  
When F = "Low", it means 5 x 8 dots format display mode  
When F = "High", 5 x11 dots format display mode.

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".
