d
(RE = 1)
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.
Hence, 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 twice.
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, 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 blinking. The quantity
of blink is assigned the highest 2 bit of CGRAM/SEGRAM.
9) Set CGRAM Address (RE = 0)
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
10) Set SEGRAM Address (RE = 1)
Set SEGRAM address to AC.
This instruction makes SEGRAM data available from MPU.
