13.3 Pixel Control
13.3.1 LCDD (PIXEL DATA) REGISTERS
The pixel registers contain bits which define the state of
each pixel. Each bit defines one unique pixel.
Table 13-4 shows the correlation of each bit in the
LCDD registers to the respective common and seg-
ment signals.
Any LCD pixel location not being used for display can
be used as general purpose RAM.
