Select the frame clock prescale using bits,
LP<3:0> (LCDPS<3:0>).
Configure the appropriate pins to function as
segment drivers using the LCDSEx registers.
Configure the appropriate pins as inputs using
the TRISx registers.
Configure the LCD module for the following
using the LCDCON register:
•
•
•
Write initial values to pixel data registers,
LCDDATA0 through LCDDATA23.

Timing source (CS<1:0>)
Sleep mode (SLPEN)

Clear LCD Interrupt Flag, LCDIF (PIR3<6>),
and if desired, enable the interrupt by setting the
LCDIE bit (PIE3<6>).
Enable the LCD module by setting the LCDEN
bit (LCDCON<7>).
If M2 or M3 bias configuration is to be used,
turn
CKSEL<1:0> (LCDREG<1:0>) to ‘00’. Set
or clear the CPEN bit (LCDREG<6>) to
select Mode 2 or Mode 3, as appropriate.
If M0 or M1 bias generation is to be used:
• Set the V
• Set or clear the CPEN bit to enable or
