PIC18F87J90 FAMILY
17.1
The LCD driver module has 33 registers:
• LCD Control Register (LCDCON)
• LCD Phase Register (LCDPS)
• LCDREG Register (LCD Regulator Control)
• Six LCD Segment Enable Registers
• 24 LCD Data Registers
17.1.1
The LCDCON register, shown in Register 17-1,
controls the overall operation of the module. Once the
module is configured, the LCDEN (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.

The
configures the LCD clock source prescaler and the type
of waveform: Type-A or Type-B. Details on these
features are provided in Section 17.2 “LCD Clock
Source”, Section 17.3 “LCD Bias Generation” and
Section 17.8 “LCD Waveform Generation”.
The LCDREG register is described in Section 17.3
“LCD Bias Generation”.
The LCD Segment Enable registers (LCDSEx)
configure the functions of the port pins. Setting the
segment enable bit for a particular segment configures
that pin as an LCD driver. The prototype LCDSE register
is shown in Register 17-3. There are six LCDSE
registers (LCDSE5:LCDSE0) listed in Table 17-1.
