LCD Registers
Preliminary
TABLE 26-1:
The LCDCON register (Register 26-1) controls the
operation of the LCD driver module. The LCDPS regis-
ter (Register 26-2) configures the LCD clock source
prescaler and the type of waveform; Type-A or Type-B.
The LCDSEn registers (Register 26-5) configure the
functions of the port pins.
The following LCDSEn registers are available:
• LCDSE0
• LCDSE1
• LCDSE2
Once the module is initialized for the LCD panel, the
individual bits of the LCDDATAn 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
As
Register 26-6.
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.
