17.1.2
Once the module is initialized for the LCD panel, the
individual bits of the LCDDATA23:LCDDATA0 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.

Bits<7:1> of these registers are not implemented in PIC18F6XJ90 devices. Bit 0 of these registers
(SEG32Cy) is always implemented.
These registers are not implemented on PIC18F6XJ90 devices.

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.
