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.
SH: Shift of entire display
When DDRAM read (CGRAM read/write) operation or SH = "Low", shift 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 = "1" : shift left,
I/D = "0" : 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 is remained 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 remains its data.
B : Cursor Blink ON/OFF Control Bit
When B = "High", cursor blink is on, that performs alternate between all the high data and display character at the
cursor position.
When B = "Low", blink is off.

Shifting of right/left cursor position or display without writing or reading of display data. This instruction is used to
correct or search display data (Refer to table 6). During 2-line mode display, cursor moves to the 2nd line after
the 40th digit of the 1st line. Note that display shift is performed simultaneously in all the lines. When displayed
data is shifted repeatedly, each line is shifted individually. When display shift is performed, the contents of the
address counter are not changed.
