21.13 Disabling the LCD Module
To disable the LCD module, write all ‘0’s to the
LCDCON register.
© 2008 Microchip Technology Inc.
Select the frame clock prescale using bits
LP<3:0> of the LCDPS register.
Configure the appropriate pins to function as
segment drivers using the LCDSEn registers.
Configure the LCD module for the following
using the LCDCON register:
Write initial values to pixel data registers,
LCDDATA0 through LCDDATA11 (LCDDATA23
on PIC16F1938).
Clear LCD Interrupt Flag, LCDIF bit of the PIR2
register and if desired, enable the interrupt by
setting bit LCDIE of the PIE2 register.
Configure bias voltages by setting the LCDRL,
LCDREF and the associated ANSELx
registers as needed.
Enable the LCD module by setting bit LCDEN of
the LCDCON register.

- Sleep mode, bit SLPEN
- Multiplex and Bias mode, bits LMUX<1:0>
Preliminary
21.14 LCD Current Consumption
When using the LCD module the current consumption
consists of the following three factors:
• Oscillator Selection
• LCD Bias Source
• Capacitance of the LCD segments
The current consumption of just the LCD module can
be considered negligible compared to these other
factors.
21.14.1
The current consumed by the clock source selected
must be considered when using the LCD module. See
Section 28.0 “Electrical Specifications” for oscillator
current consumption information.
21.14.2
The LCD bias source, internal or external, can contrib-
ute significantly to the current consumption. Use the
highest possible resistor values while maintaining
contrast to minimize current.
21.14.3
The LCD segments which can be modeled as capaci-
tors which must be both charged and discharged every
frame. The size of the LCD segment and its technology
determines the segment’s capacitance.
