KS0074 34COM/80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
INITIALIZING
1) Initializing by Internal Reset Circuit
When the power is turned on, KS0074 is initialized automatically by power on reset circuit.
During the initialization, the following instructions are executed, and BF(Busy Flag) is kept "High"(busy state) to the end of
initialization.
Display Clear instruction
Write "20H" to all DDRAM
Set Functions instruction
DL = 1 : 8-bit bus mode
N = 1 : 2-line display mode
RE = 0 : Extension register disable
BE = 0 : CGRAM/SEGRAM blink OFF
DH = 0 : Horizontal scroll enable
REV = 0 : Normal display (Not reversed display)
Control Display ON/OFF instruction
D = 0 : Display OFF
C = 0 : Cursor OFF
B = 0 : Blink OFF
Set Entry Mode instruction
I/D = 1 : Increment by 1
S = 0 : No entire display shift
BID = 0 : Normal direction segment port
Set Extension Function instruction
FW = 0 : 5-dot font width character display
B/W = 0 : Normal cursor (8th line)
NW = 0 : Not 4-line display mode, 2-line mode is set because of N("1")
Enable Shift instruction
HS = 0000 : Scroll per line disable
DS = 0000 : Shift per line disable
Set scroll Quantity instruction
SQ = 000000 : Not scroll
2) Initializing by Hardware RESET input
When RESET pin = "Low", KS0074 can be initialized like the case of power on reset.
During the power on reset operation, this pin is ignored.
