The LCDCON register, shown in Register 20-1,
controls the overall operation of the module. Once the
module is configured, the LCDEN (LCDCON<7>) bit is
used to enable or disable the LCD module. The LCD
panel can also operate during Sleep by clearing the
SLPEN (LCDCON<6>) bit.
The
configures the LCD clock source prescaler and the type
of waveform, Type-A or Type-B. For details on these
features, see Section 20.2 “LCD Clock Source
Selection”, Section 20.3 “LCD Bias Types” and
Section 20.8 “LCD Waveform Generation”.
