The LCD0 to LCD20 registers provide 21 bytes of display memory. Depending on the duty cycle and package type,
not all display memory can be used by the LCD controller. Any display memory that is unused by the LCD controller
can be used for application purposes if desired. The following tables show the display memory mapping for different
duty cycle and package configurations.
