5 Page 11.2 Instruction Description
1)Clear Display
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0000000001
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").
2) Return Home
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
000000001 -
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.
3) Entry Mode Set
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 0 1 I/D SH
Set the moving direction of cursor and display.
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.
SH: Shift of entire display
When DDRAM read (CGRAM read / write) operation or SH = "Low", shift of entire display is
not performed. If SH = "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.
4) Display ON/OFF Control
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 0 0 1 DCB
Control display / cursor / blink ON / OFF 1 bit register.
D: Display ON / OFF control bit
When D = "High", entire display is turned on.
When D = "Low", display is turned off, but display data is remained in DDRAM.
C: Cursor ON / OFF control bit
When C = "High", cursor is turned on.
When C = "Low", Cursor is disappeared in current display, but I/D register remains its data.
B: Cursor Blink ON / OFF control bit
When B = "High", cursor blink is on, that performs alternate between all the high data and
display character at the cursor position.
When B = "Low", blink is off.
