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", entire display is turned off, but display data is 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, performs alternately between all high data (black pattern) and display
character at the cursor position.
When B = "Low", blink is off.

Without writing or reading of display data, shift right/left the cursor position or display. This instruction is used to
correct or search display data. (Refer to Table 4) during 2-line mode display, cursor moves to the 2nd line after 8th
digit of 1st line. Note that display shift is performed simultaneously in all the line. When displayed data is shifted
repeatedly, each line is shifted individually. When display shift is performed, the contents of address counter are not
changed.
