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. Entry mode is set to increment mode (I/D = "1")

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.
When S = "High", after DDRAM write, the entire display of all lines is shifted to the right (I/D = "0")or to the left
(I/D = "1") but it will seem as if the cursor does not move. When S = "Low", or DDRAM read, or CGRAM
read/write operation, shift of entire display is not performed.
