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.
If using the internal reference resistors for
biasing, enable the internal reference ladder
and:
• Define the Mode A and Mode B interval by
• Define the low, medium or high ladder for
• Set the VLCDxPE bits and enable the
using the LRLAT<2:0> bits (LCDRL<2:0>)
Mode A and Mode B by using the LRLAP<1:0>
bits (LCDRL<7:6>) and the LRLBP<1:0> bits
(LCDRL<5:4>), respectively

Configure the following LCD module functions
using the LCDCON register:
• Multiplex and Bias mode – LMUX<1:0> bits
• Timing Source – CS<1:0> bits
• Sleep mode – SLPEN bit
Write initial values to the pixel data registers,
LCDDATA0 through LCDDATA23.
Clear the 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>).
