I/D SH
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 way as DDRAM, when reading from or writing to CGRAM.
SH: Shift of entire display
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.
D: Display ON/OFF control bit
When D = “High”, entire display is turned on.
When D = “Low”, display is turned off, but display data remains in DDRAM.
C: Cursor ON/OFF control bit
When C = “High”, cursor is turned on.
When C = “Low”, cursor is disappeared in current display, but I/D register preserves its data.
B: Cursor Blink ON/OFF control bit
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.
