The Liquid Crystal Display (LCD) driver module
generates the timing control to drive a static or
multiplexed LCD panel. In the PIC16F913/916 devices,
the module drives the panels of up to four commons
and up to 16 segments. In the PIC16F914/917 devices,
the module drives the panels of up to four commons
and up to 24 segments. In the PIC16F946 device, the
module drives the panels of up to four commons and up
to 42 segments. The LCD module also provides control
of the LCD pixel data.
The LCD driver module supports:
• Direct driving of LCD panel
• Three LCD clock sources with selectable prescaler
• Up to four commons:
• Segments up to:
• Static, 1/2 or 1/3 LCD Bias
10.1
The module contains the following registers:
• LCD Control Register (LCDCON)
• LCD Phase Register (LCDPS)
• Up to 6 LCD Segment Enable Registers (LCDSEn)
• Up to 24 LCD Data Registers (LCDDATA)

LCD Registers
COM3 and SEG15 share the same
physical pin on the PIC16F913/916,
therefore SEG15 is not available when
using 1/4 multiplex displays.

The LCDCON register (Register 10-1) controls the
operation of the LCD driver module. The LCDPS
register (Register 10-2) configures the LCD clock
source prescaler and the type of waveform; Type-A or
Type-B.
configure the functions of the port pins.
The following LCDSE registers are available:
• LCDSE0
• LCDSE1
• LCDSE2
• LCDSE3
• LCDSE4
• LCDSE5
Once the module is initialized for the LCD panel, the
individual bits of the LCDDATA<11:0> registers are
cleared/set to represent a clear/dark pixel, respectively:
• LCDDATA0
• LCDDATA1
• LCDDATA2
• LCDDATA3
• LCDDATA4
• LCDDATA5
• LCDDATA6
• LCDDATA7
• LCDDATA8
• LCDDATA9
• LCDDATA10 SEG<15:8>COM3
• LCDDATA11 SEG<23:16>COM3
The following additional registers are available on the
PIC16F946 only:
• LCDDATA12 SEG<31:24>COM0
• LCDDATA13 SEG<39:32>COM0
• LCDDATA14 SEG<41:40>COM0
• LCDDATA15 SEG<31:24>COM1
• LCDDATA16 SEG<39:32>COM1
• LCDDATA17 SEG<41:40>COM1
• LCDDATA18 SEG<31:24>COM2
• LCDDATA19 SEG<39:32>COM2
• LCDDATA20 SEG<41:40>COM2
• LCDDATA21 SEG<31:24>COM3
• LCDDATA22 SEG<39:32>COM3
• LCDDATA23 SEG<41:40>COM3
As
Register 10-4.
Once the module is configured, the LCDEN bit of the
LCDCON register is used to enable or disable the LCD
module. The LCD panel can also operate during Sleep
by clearing the SLPEN bit of the LCDCON register.
