8) Shift/Scroll Enable (RE = 1)
HS: Horizontal Scroll per Line Enable
This instruction makes valid dot shifts by a display line unit.
HS1, HS2, HS3 and HS4 indicate each line to be dot scrolled, and each scroll is performed individually in
each line.
If the line, in 1-line display mode or the 1st line in 2-line display mode is to be scrolled, set HS1 and HS2 to
“High”. If the 2nd line scroll is needed in 2-line mode, set HS3 and HS4 to “High” (Refer to Table 8).
DS: Display Shift per Line Enable
This instruction selects the line to be shifted according to each line mode in display shift right/left
instruction. DS1, DS2, DS3 and DS4 indicate each line to be shifted, and each shift is performed individually
in each line.
If DS1 and DS2 are set to “High” (enable) in 2-line mode, only 1st line is shifted, and the 2nd line is not
shifted. When only DS1
“Low” (disable), no display is shifted.
