@ (RE = 1)
DL : Interface data length control bit
8-bit or 4-bit bus mode.
N : Display line number control bit
RE : Extended function registers enable bit
BE : CGRAM/SEGRAM data blink enable bit
10) Set CGRAM Address (RE = 0)
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
11) Set SEGRAM Address (RE = 1)
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
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
When 4-bit bus mode, it is required to transfer 4-bit data twice.
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, it means 4-line mode independent of N bit.
When RE = "High", extended function set registers, SEGRAM address set registers, BID bit, HS/DS bits of
shift/scroll enable instruction and BE bits of function set register can be accessed.
BE = “High”, makes user font of CGRAM and segment of SEGRAM blinking. The quantity of blink is
assigned the highest 2 bit of CGRAM/SEGRAM.
