17.1.2
Once the module is initialized for the LCD panel, the
individual bits of the LCDDATA registers are cleared or
set to represent a clear or dark pixel, respectively.
Specific sets of LCDDATA registers are used with
specific segments and common signals. Each bit
represents a unique combination of a specific segment
connected to a specific common.

Individual LCDDATA bits are named by the convention
“SxxCy”, with “xx” as the segment number and “y” as
the common number. The relationship is summarized
in Table 17-2. The prototype LCDDATA register is
shown in Register 17-4.
