11.6 Configuring the LCD Module
The following is the sequence of steps to follow to con-
figure the LCD module.
1. Select the frame clock prescale using bits
LP3:LP0 (LCDPS<3:0>).
2. Configure the appropriate pins to function as
segment drivers using the LCDSE register.
3. Configure the LCD module for the following
using the LCDCON register:
- Multiplex mode and Bias, bits
LMUX1:LMUX0
- Timing source, bits CS1:CS0
- Voltage generation, bit VGEN
- SLEEP mode, bit SLPEN
4. Write initial values to pixel data registers,
LCDD00 through LCDD15.
5. Clear LCD interrupt flag, LCDIF (PIR1<7>), and
if desired, enable the interrupt by setting bit
LCDIE (PIE1<7>).
6. Enable the LCD module, by setting bit LCDEN
(LCDCON<7>).
