LCD segment driver output pins.
Segment driver output voltage is controlled by display data and FR signal.
LCD common driver output pins.
Common driver output voltage is controlled by internal scanning data and FR signal.
Common drive output for the icons. There are two COMS pin, COMS(R), COMS(L).
They output same signal. When in master/slave mode, the same signal is output by both
master and slave.
Static segment driver output pin. This pin is paired with FRS pin.
Static segment driver output pin. This pin is paired with FR pin.
