9.10 Configuring the LCD Module
The following is the sequence of steps to configure the
LCD module.
1. Select the frame clock prescale using bits
LP<3:0> (LCDPS<3:0>).
2. Configure the appropriate pins to function as
segment drivers using the LCDSEn registers.
3. Configure the LCD module for the following
using the LCDCON register:
-Multiplex and Bias mode, bits LMUX<1:0>
-Timing source, bits CS<1:0>
-Sleep mode, bit SLPEN
4. Write initial values to pixel data registers,
LCDDATA0 through LCDDATA11.
5. Clear LCD Interrupt Flag, LCDIF (PIR2<4>) and
if desired, enable the interrupt by setting bit
LCDIE (PIE2<4>).
6. Enable bias voltage pins (VLCD<3:1>) by
setting VLCDEN (LCDCON<4>).
7. Enable the LCD module by setting bit LCDEN
(LCDCON<7>).
