I/D

SH

Set the moving direction of cursor and display.

I/D : Increment / decrement of DDRAM address (cursor or blink)

When I/D = “1”, cursor/blink moves to right and DDRAM address is increased by 1.

When I/D = “0”, cursor/blink moves to left and DDRAM address is decreased by 1.

* CGRAM operates the same as DDRAM, when reading from or writing to CGRAM.

SH: Shift of entire display

When DDRAM is in read (CGRAM read/write) operation or SH = “0”, shift of entire display is not performed.

If SH = “1” and in DDRAM write operation, shift of entire display is performed according to I/D value

(I/D = “1” : shift left, I/D = “0” : shift right).

When C = “0”, cursor disappears in current display, but I/D register retains its data.

When B = “1”, cursor blink is on, which performs alternately between all the “1” data and display characters

at the cursor position.
