8) Shift/Scroll Enable (RE = 1)
c
(DH = 0)
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 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)
d
(DH = 1)
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 DS1 and DS2 is set 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.
