NAME
DESCRIPTION
for logical circuit(+3V,+5V)
0V(GND)
Power supply Bias voltage level for LCD driving.
Input voltage to the voltage converter to
generate LCD drive voltage(Vci = 1.0 -4.5V).
Segment output Segment signal output for LCD drive.

Oscillator
When use internal oscillator, connect external
Rf resistor.
If external clock is used, connect it to OSC1.

To use the voltage converter(2 times /3 times),
capacitance input these pins must be connected to the external
capacitance.

When IE = "High", Instruction set is
selected as Table 6.
When IE = "Low", Instruction set is selected as
Table 10.
The value of Vci is converted two times.
To use three times converter, the same
capacitance as that of C1-C2 should be
connected here.
The value of Vci is converted three times.
