SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE
MODEL NO: 19264-05
Busy Flag
Busy flag indicates that KS0108B is operating or not operating. When busy flag is high, KS0108B is in internal
operating. When busy flag is low, KS0108B can accept the data or instruction.
DB7 indicates busy flag of the KS0108B.
E
Busy flag
Display On/Off Flip-Flop
The display on/off flip-flop makes on/off of the liquid crystal display. When flip-flop is reset (logical low),
selective voltage or non selective voltage appears on segment output terminals. When flip-flop is set (logical high), non
selective voltage appears on segment output terminals regardless of display RAM data.
The display on/off flip-flop can changes status by instruction. The display data at all segment disappear while
RSTB is low. The status of the flip-flop is output to DB5 by status read instruction.
X Page Register
X page register designates page of the internal display data RAM. It has not count function. An address is set by
instruction.
Y Address Counter
Y address counter designates address of the internal display data RAM. An address is set by instruction and is
increased by 1 automatically by read or write operations of display data.
Display Data RAM
Display data RAM stores a display data for liquid crystal display. To express on state of dot matrix of liquid
crystal display, write data 1. The other way, off state writes 0.
DB<0:7>=0 Y address 0 S1
DB<0:7>=63 Y address 63 S64
Display Start Line Register
The display start line register indicates address of display data RAM to display top line of liquid crystal display.
Bit data (DB<0:5>) of the display start line set instruction is latched in display start line register. It is used for scrolling of
the liquid crystal display screen.
