0 0 0 0 0 1 S/C R/L - -<br />

Shifts right/left cursor position or display without writing or reading of display data.<br />

This instruction is used to correct or search display data (Refer to Table 7).<br />

During 2-line mode display, cursor moves to the 2nd line after the 40th digit of the 1st line.<br />

In 4-line mode, cursor moves to the next line, only after every 20th digit of the current line.<br />

Note that display shift is per<strong>for</strong>med simultaneously in all the lines enabled by DS1 - S4 in the Shift Enable<br />

instruction.<br />

When displayed data is shifted repeatedly, each line is shifted individually.<br />

When display shift is per<strong>for</strong>med, the contents of the address counter are not changed.<br />

During low power consumption mode, display shift may not be per<strong>for</strong>med normally.<br />
