Function
Outputs the latch pulse of segment extension
driver.Cam also be used as a shift clock of common
extention driver. Exters tristate when both EXT1 and
EXT2 are 0.
Outputs shift clock of segment extension driver. Can
also be used as a common extension driver latch clock.
Enters tristate when both EXT1 and EXT2 are 0.
Outputs data of extension driver. Data after the 72nd
dot is output. Enters tristate when EXT1 bit is 0.
Acts as an alternating current signal of extension driver.
Enters tristate when both EXT1 and EXT2 bits are 0.
Power supply for LCD drive

V
When crystal oscillation is performed, an external
resistor must be connected. When the pin input is an
external clock, it must be input to OSC1.
Inputs voltage to the booster to generate the liquid
crystal display drive voltage.
Vci is reference voltage and power supply for the
booster.
Vci: 1.0V to 5.0V
Voltage input to the Vci pin is boosted twice and output.
When the voltage is boosted three times, a capacitor
with the same capacitance as that of C1–C2 should be
connected here.
Voltage input to the Vci pin is boosted three times and
output.
