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.
When 4-bit bus mode, it needs 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", it means 1-line display mode.
When N = "High", 2-line display mode is set.
When NW = "High", N bit is invalid, it means 4-line mode independent of N bit.
RE:
Extended function registers enable bit
At this instruction, RE must be "Low".

It is variable only when NW bit of extended function set instruction is Low.
When N = "Low", it means 1-line display mode.
When N = "High", 2-line display mode is set.
When NW = "High", N bit is invalid, it means 4-line mode independent of N bit.
RE:
Extended function registers enable bit
When RE = "High", extended function set registers, SEGRAM address set registers, HS bits of scroll
enable instruction and BE bits of function set register can be accessed.
BE:
CGRAM/SEGRAM data blink enable bit
If BE is "High", It makes user font of CGRAM and segment of SEGRAM blink. The quantity of blink is
assigned the highest 2 bit of CGRAM/SEGRAM.
