98 / 182 page  PIC16C925/926 DS39544A-page 96 Preliminary 2001 Microchip Technology Inc. 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>).
