Clear all the display data by writing "20H" (space code) to all DDRAM address, and set DDRAM address to
"00H" into AC (address counter). Return cursor to the original status, namely, bring the cursor to the left edge
on first line of the display. Make entry mode increment (I/D = "1").
l Return Home
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0000001X
Return Home is cursor return home instruction. Set DDRAM address to "00H" into the address counter.
Return cursor to its original site and return display to its original status, if shifted. Contents of DDRAM do not
change.
l Entry Mode Set
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 0 0 0 0 1 I/D S
Set the moving direction of cursor and display.
Ø I/D : Increment / decrement of DDRAM address (cursor or blink)
When I/D = "High", cursor/blink moves to right and DDRAM address is increased by 1.
When I/D = "Low", cursor/blink moves to left and DDRAM address is decreased by 1.
* CGRAM operates the same as DDRAM, when read from or write to CGRAM.
Ø 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).
