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.
Common output Common signal output for LCD drive.

Oscillator
When use internal oscillator, connect external Rf External
resistor.
resistor/oscillator
If external clock is used, connect it to OSC1.
(OSC1)
External
To use the voltage converter(2 times /3 times),
capacitance input
these pins must be connected to the external
capacitance.
Reset pin Initialized to Low
Select pin When IE = "High", Instruction set is
of
selected as Table 6.

When IE = "Low", Instruction set is selected as
Table 10.
Two times
converter
output
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.
Three times The value of Vci is converted three times.
