to “00H” into AC (address counter).
Set the moving direction of cursor and display.
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 increased by 1.
*CGRAM operates the same way as DDRAM, when reading from or writing to CGRAM.
When DDRAM read (CGRAM read/write) operation or SH=“Low”, shifting 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=“high”.
shift left, I/D=“Low”. Shift right).
Control display/cursor/blink ON/OFF 1 bit register.
When D=“High”, entire display is turned on.
When D=“Low”, display is turned off, but display data remains in DDRAM.
When D=“High”, cursor is turned on.
When D=“Low”, cursor is disappeared in current display, but I/D register preserves its data.
When B=“High”, cursor blink is on, which performs alternately between all the “High” data and display
characters at the cursor position.
When B=“Low”, blink is off.
This instruction is used to correct or search display data.
During 2-line mode display, cursor moves to the 2nd line after the 40th digit of the 1st line.
Note that display shift is performed simultaneously in all the lines.

Clear all the display data by writing “20H” (space code) to all DDRAM address, and set DDRAM address
Return cursor to the original status, namely, bring the cursor to the left edge on the fist line of the display.
Make the entry mode increment (I/D=“High”).
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 does not change.
SH: shift of entire display
I/D: increment / decrement of DDRAM address (cursor or blink)
D: Display ON/OFF control bit
C: cursor ON/OFF control bit
B: Cursor blink ON/OFF control bit
Shifting of right/left cursor position or display without writing or reading of display data.
