Shift right/left cursor position or display, without writing or reading of display data, this instruction is use to correct
or search display data (refer to Table 7). During 2-line mode display, cursor moves to the 2nd line after 40th digit
of 1st line. When 4-line mode, cursor moves to the next line, only after every 20th digit of the current line. Note
that display shift is performed simultaneously in all the line enabled by DS1-DS4 in the shift enable instruction.
When displayed data is shifted repeatedly, each line shifted individually. When display shift is performed, the
contents of address counter are not changed. During low power consumption mode, display shift may not be
performed normally.
