Bias voltage level for LCD driving.
Input voltage to the voltage converter to
generate LCD drive voltage
(Vci = 1.0 to 4.5 V).
Segment signal output for LCD drive.
Common signal output for LCD drive.
When using internal oscillator, connect
external Rf resistor
If external clock is used, connect it to
OSC1.
When EXT = “High”,
each outputs latch clock and shift clock
for extension driver.
To use the voltage converter (2 times /
times), these pins must be connected to
the external capacitance.
When EXT = “High”, outputs the
alternating signal to convert LCD driver
waveform to AC for extension driver.
When EXT = “High”, outputs extension
driver data (the 61th dot's data)
When EXT = “High”, enables extension
diver control signal, When EXT = “Low”,
suppresses extra current consumption
and CLK1/CLK2/M/D should be open.
Initialized to Low
When IE = “Low”, instruction set is
selected as Table 10.
When IE = “High”, instruction set is
selected as Table 6.
