PIC18F6390/6490/8390/8490
22.1
The LCD driver module has 32 registers:
• LCD Control Register (LCDCON)
• LCD Phase Register (LCDPS)
• Six LCD Segment Enable Registers
• 24 LCD Data Registers
The LCDCON register, shown in Register 22-1,
controls the overall operation of the module. Once the
module is configured, the LCDEN (LCDCON<7>) bit is
