KS0074
1) Display Clear
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, 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").
2) Return Home
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.
3) Entry Mode Set
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/SEGRAM operates identically to the DDRAM, when reading from or writing to CGRAM/SEGRAM.
the right (I/D = "0") or to the left(I/D = "1").
display is not performed.
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

But it will seem as if the cursor does not moving.
