Description
34com/120seg Driver & Controller For Dot Matrix Lcd
Manufacturer
Samsung Semiconductor, Inc.
Datasheet
KS0078
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
shift/scroll enable instruction and BE bits of function set register can be accessed.
BE : CGRAM/SEGRAM data blink enable bit
assigned the highest 2 bit of CGRAM/SEGRAM.
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.
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
It is variable only when NW bit of extended function set instruction is Low.
If BE is "High", It makes user font of CGRAM and segment of SEGRAM blinking. The quantity of blink is
(RE = 1)
