7) Scroll Enable (RE = 1)
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)
8) Function Set
c
(RE = 0)
DL : Interface data length control bit
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU.
So to speak, DL is a signal to select
8-bit or 4-bit bus mode.
In 4-bit bus mode, it is required to transfer 4-bit data by two times.
N : Display line number control bit
It is variable only when NW bit of extended function set instruction is Low.
When N = "Low", 1-line display mode is set.
When N = "High", 2-line display mode is set.
When NW = "High", N bit is invalid, t means 4-line mode independent of N bit.
RE : Extended function registers enable bit
At this instruction, RE must be "Low".
