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.
