LCD R bias / C bias
LCD can be configured as R bias or C bias. In R bias, Seg0-Seg19 all can be used. In C bias, only
Seg0-Seg15 can be used.
The circuit for LCD interface will be little different in different Vdd and LCD bias when using capacitor for LCD
biasing (C bias). Please see the table below:
Vdd = 3 V
