3) Entry Mode Set
Set the moving direction of cursor and display.

does not moving.
display is not performed.






























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.
When S = "High", after DDRAM write, the entire display of all lines is shifted to
When S = "Low", or DDRAM read, or CGRAM/SEGRAM read/write operation, shift of entire
DDRAM address to "00H" into AC (address counter). Return cursor to the original status,
hence, bring the cursor to the left edge on first line of the display.
And entry mode is set to increment mode (I/D = "1").
Set DDRAM address to "00H" into the address counter. Return cursor to its original
Contents of DDRAM does not change.
* CGRAM/SEGRAM operates identically to the DDRAM, when reading from or writing to CGRAM/SEGRAM.










































But it will seem as if the cursor
