LCD SEGMENT AND DATA

REGISTERS

The LCDCON register (Register 27-1) controls the

operation of the LCD driver module. The LCDPS regis-

ter (Register 27-2) configures the LCD clock source

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

The LCDSEn registers (Register 27-5) configure the

functions of the port pins.

The following LCDSEn registers are available:

• LCDSE0 SE<7:0>

• LCDSE1 SE<15:8>

•

LCDSE2 SE<23:16>(1)

• LCDSE3 SE<31:24>

• LCDSE4 SE<39:32>

• LCDSE5 SE<45:40>

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

• LCDDATA2

SEG<23:16>COM0

• LCDDATA3

SEG<7:0>COM1

• LCDDATA4

SEG<15:8>COM1

• LCDDATA5

SEG<23:16>COM1

• LCDDATA6

SEG<7:0>COM2

• LCDDATA7

SEG<15:8>COM2

• LCDDATA8

SEG<23:16>COM2

• LCDDATA9

SEG<7:0>COM3

• LCDDATA10 SEG<15:8>COM3

• LCDDATA11 SEG<23:16>COM3

• LCDDATA12 SEG<31:24>COM0

• LCDDATA13 SEG<39:32>COM0

• LCDDATA14 SEG<45:40>COM0

• LCDDATA15 SEG<31:24>COM1

• LCDDATA16 SEG<39:32>COM1

• LCDDATA17 SEG<45:40>COM1

• LCDDATA18 SEG<31:24>COM2

• LCDDATA19 SEG<39:32>COM2

• LCDDATA20 SEG<45:40>COM2

• LCDDATA21 SEG<31:24>COM3

• LCDDATA22 SEG<39:32>COM3

• LCDDATA23 SEG<45:40>COM3

detailed

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.
