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 />
Table 7. Shift patterns according to S/C and R/L bits<br />
S/C R/L Operation<br />
0 0 Shift cursor to the left, ADDRESS COUNTER is decreased by 1<br />
0 1 Shift cursor to the right, ADDRESS COUNTER is increased by 1<br />
1 0 Shift all the display to the left, cursor moves according to the display<br />
1 1 Shift all the display to the right, cursor moves according to the display
