Interface

Power Supply

Bias voltage level for LCD driving

Input voltage to the voltage converter to

generate LCD drive voltage

(Vci = 1.0 to 4.5V).

Segment signal output for LCD drive.

When using internal oscillator, connect

external Rf resistor.

If external clock is used, connect it to

OSC1.

clock and shift clock for extension driver.

driver

To use the voltage converter (2 times /3

times), these pins must be connected to

the external capacitance.

External

capacitance

When EXT = "High", outputs the

alternating signal to convert LCD driver

waveform to AC for Extension driver.

Extension

driver

When EXT = "High", outputs extension

driver data (the 61th dot's data)

Extension

driver control signal enable, When EXT

= "Low", suppress extra current

consumption and CLK1,CLK2,M,D

should be open.

Initialized to Low

selected as Table 6.

When IE = "Low", instruction set is

selected as Table 10.
