Legend:
Note 1: These pixels do not display, but can be used as general purpose RAM.
Address
Select the frame clock prescale using bits
LP3:LP0 (LCDPS<3:0>).
Configure the appropriate pins to function as
segment drivers using the LCDSE register.
Configure the LCD module for the following
using the LCDCON register:
- Multiplex mode and Bias, bits
- Timing source, bits CS1:CS0
- Voltage generation, bit VGEN
- SLEEP mode, bit SLPEN
LMUX1:LMUX0
Configuring the LCD Module
x = unknown, u = unchanged, - = unimplemented, read as '0'. Shaded cells are not used by the LCD module.

Write initial values to pixel data registers,
LCDD00 through LCDD15.
Clear LCD interrupt flag, LCDIF (PIR1<7>), and
if desired, enable the interrupt by setting bit
LCDIE (PIE1<7>).
Enable the LCD module, by setting bit LCDEN
(LCDCON<7>).
