Bias voltage level for LCD driving.
Input voltage to the voltage converter to
generate LCD drive voltage
(Vci = 2.5 - 4.5V).
Segment output Segment signal output for LCD drive.

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.
Select Interface mode with the MPU.
When IM = "Low": Serial mode,
When IM = "High": 4-bit/8-bit bus mode.
