The Liquid Crystal Display (LCD) driver module generates
the timing control to drive a static or multiplexed LCD
panel. In the PIC16F914/917 devices (PIC16F914/917),
the module drives the panels of up to four commons and
up to 24 segments and in the PIC16F913/916 devices
(PIC16F913/916), the module drives the panels of up to
four commons and up to 16 segments. It 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:
• Up to 24 (in PIC16F914/917 devices)/16 (in
• Static, 1/2 or 1/3 LCD Bias
The module has 32 registers:
• LCD Control Register (LCDCON)
• LCD Phase Register (LCDPS)
• Three LCD Segment Enable Registers
• 24 LCD Data Registers (LCDDATA<11:0>)
The LCDCON register, shown in Register 9-1, controls
the operation of the LCD driver module. The LCDPS
register, shown in Register 9-2, configures the LCD
clock source prescaler and the type of waveform;
Type-A or Type-B. The LCDSE<2:0> registers configure
the functions of the port pins:
• LCDSE0
• LCDSE1
• LCDSE2
As an example, LCDSEn is detailed in Register 9-3.

Once the module is initialized for the LCD panel, the
individual bits of the LCDDATA<11:0> registers are
cleared/set
respectively:
• LCDDATA0
• LCDDATA1
• LCDDATA2
• LCDDATA3
• LCDDATA4
• LCDDATA5
• LCDDATA6
• LCDDATA7
• LCDDATA8
• LCDDATA9
• LCDDATA10 SEG15COM3:SEG8COM3
• LCDDATA11 SEG23COM3:SEG16COM3
As an example, LCDDATAx is detailed in Register 9-4.
Once
(LCDCON<7>) bit is used to enable or disable the LCD
module. The LCD panel can also operate during Sleep
by clearing the SLPEN (LCDCON<6>) bit.
Note:

in PIC16F913/916 devices will not affect the
status of any pixel and these registers can
be used as General Purpose Registers.
