Power supply
Reference power supply for generating the liquid-
crystal application voltage. Supply a voltage in the
range VLCD/2 to VLCD – 0.1 V to pins V0–V4, and a
voltage in the range 0.1 V to VLCD/2 to pins V5–V9.
V4 to V0

CL1
1
Input
Data of one line is transferred to the latch at the rising
edge of this clock, and the liquid-crystal application
voltage is output at the falling edge. One pulse must
be input in each horizontal period.
CL2
1
Input
Display data is latched at the rising edge of this clock.
After the start pulse input, the start pulse output goes
high at the rising edge of the 64th clock, and this
becomes the start pulse of the next-stage driver. The
65th clock of the first-stage driver is the start-pulse
latch clock of the next-stage driver.
After the start pulse input, display data latching is
halted automatically when 66 clock pulses are input.
POL2
1
Input
Data-polarity inversion signal to reduce power
consumption of data bus lines in the interface.
When POL2 is high, display data is inverted in the
driver.
When POL2 is low, display data is input without
inversion in the driver.
