The LCDCON register (Register 18-1) controls the

operation of the LCD driver module. The LCDPS regis-

ter (Register 18-2) configures the LCD clock source

prescaler and the type of waveform; Type-A or Type-B.

The LCDSEn registers (Register 18-5) configure the

functions of the port pins.

The following LCDSEn registers are available:

• LCDSE0 SE<7:0>

• LCDSE1 SE<15:8>

• LCDSE3 SE<26:24>

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 SEG<7:0>COM0

• LCDDATA1 SEG<15:8>COM0

• LCDDATA3 SEG<7:0>COM1

• LCDDATA4 SEG<15:8>COM1

• LCDDATA6 SEG<7:0>COM2

• LCDDATA7 SEG<15:8>COM2

• LCDDATA9 SEG<7:0>COM3

• LCDDATA10 SEG<15:8>COM3

• LCDDATA12 SEG<26:24>COM0

• LCDDATA15 SEG<26:24>COM1

• LCDDATA18 SEG<26:24>COM2

• LCDDATA21 SEG<26:24>COM3

As an example, LCDDATAn is detailed in

Register 18-6.

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.
