Entry Mode Set
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Code 0 0 0 0 0 0 0 1 I/D S
Set the moving direction of cursor and display.
I/D : Increment / decrement of DDRAM address (cursor or blink)
When I/D = "High", cursor moves to right and DDRAM address is increased by 1.
When I/D = "Low", cursor moves to left and DDRAM address is decreased by 1.
* CGRAM operates the same as DDRAM, when read from or write to CGRAM.
S: Shift of entire display
When DDRAM read (CGRAM read/write) operation or S = "Low", shift of entire display is not performed. If
S = "High" and DDRAM write operation, shift of entire display is performed according to I/D value (I/D =
"1" : shift left, I/D = "0" : shift right).

Set CGRAM Address
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0
Code
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
Set DDRAM Address
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Code 0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0
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".
