Character generator select:
Common signals direction select:
0:Com1~24'Row address 23~0(Invert)
1:Com1~24'Row address 0~23(Normal)
Segment signals direction select:
0:Seg1~100&Column address 99~0(Invert)
1:Seg1~100&Column address 0~99(Normal)
Common signals that are not used are changed
to non-selection waveform. COM9 to COM16
are non-selection waveforms at 1/8 or 1/9 duty factor
ICON common signals
Select “N3” pin for common or segment waveform output
(follow up table 2 defined)

The built-in voltage follower circuit selection
For voltage booster circuit(V
External capacitor about 0.1u~4.7uf
Input the voltage to booster
DC/DC voltage converter. Connect a capacitor between this
terminal and VIN when the built-in booster is used.
Power supply for LCD drive
V0-Vss = 7V (Max)
Built-in/external Voltage follower circuit
VDD : 2.7V to 5.5V, VSS: 0V
Internal/External oscillation select
0:external clock
1:internal oscillation
When the pin input is an external clock, it must be input to
OSC.
When the on-chip oscillator is used, it must be connected
to VDD.
TEST1 must connect to VDD.
