HS:
Horizontal scroll per line enable
This instruction makes valid dot shift 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 you want to scroll the line in 1-line display mode or the 1st line in 2-line display mode, set HS1 and
HS2 to "High". If the 2nd line scroll is needed in 2-line mode, set HS3 and HS4 to "High".

DS:
Display shift per line enable
This instruction selects shifting 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 you set DS1 and DS2 to "High" (enable) in 2 line mode, only the 1st line is shifted and the 2nd line
is not shifted. When only DS1 = "High", only the half of the 1st line is shifted. If all the DS bits (DS1 to
DS4) are set to "Low" (disable), no display is shifted.
