8-Bit CMOS Microcontroller with LCD Driver

Microchip Technology 

PIC16C9XX

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.
