0V(GND)
Bias voltage level for LCD driving.
Input voltage to the voltage converter to
generate LCD drive voltage(Vci = 1.0 -4.5V).
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),
these pins must be connected to the external
capacitance.
Initialized to Low
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.
