Control display/cursor/blink ON/OFF 1bit 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. If fosc has 270kHz frequency, blinking has 370 ms interval.
When B = "Low", blink is off.

Without writing or reading of display data, shift right/left cursor position or display. This instruction is used to
correct or search display data (refer to Table 7). During 2-line mode display, cursor moves to the 2nd line after
48th digit of 1st line. In 4-line mode, cursor moves to the next line, only after every 24th digit of the current line.
Note that display shift is performed simultaneously in all the line. When displayed data is shifted repeatedly, each
line shifted individually. When display shift is performed, the contents of address counter are not changed.
