Effects of a Reset
Configuring the LCD Module
The LCD module is disabled, but the LCD pins are configured as LCD drivers. This ensures that
the microcontroller does not damage the LCD glass by accidently having a DC voltage across a
segment.
The following is the sequence of steps to follow to configure the LCD module.
1.
2.
3.
4.
5.
6.
- Multiplex mode and Bias, selected by the LMUX1:LMUX0 bits
- Timing source, selected by the CS1:CS0 bits
- Voltage generation, enabled by the VGEN bit
- Sleep mode operation, enabled by the SLPEN bit
Select the frame clock prescale using the LP3:LP0 bits (LCDPS<3:0>).
Configure the appropriate pins to function as segment drivers using the LCDSE register.
Configure the LCD module for the following using the LCDCON register.
Write initial values to pixel data registers, LCDD00 through LCDD15.
Clear LCD interrupt flag bit, LCDIF, and if desired, enable the interrupt by setting the
LCDIE bit.
Enable the LCD module, by setting the LCDEN bit (LCDCON<7>).
