Select the frame clock prescale using bits,
LP3:LP0 (LCDPS<3:0>).
Configure the appropriate pins to function as
segment drivers using the LCDSEx registers.
Configure the LCD module for the following
using the LCDCON register:
- Multiplex and Bias mode, LMUX1:LMUX0
- Timing source, CS1:CS0 bits
- Sleep mode, SLPEN bit
bits

Write initial values to Pixel Data registers,
LCDDATA0 through LCDDATA23.
Clear LCD Interrupt Flag, LCDIF (PIR3<6>),
and if desired, enable the interrupt by setting bit,
LCDIE (PIE3<6>).
Enable the LCD module by setting bit, LCDEN
(LCDCON<7>).
