Liquid Crystal Display (LCD)
2.0 LCD REGISTERS
The LCD driver module has 40 registers:
• LCD Control Register (LCDCON)
• LCD Phase Register (LCDPS)
• LCD Voltage Regulator Control Register (LCDREG)
• LCD Reference Ladder Control Register (LCDREF)
• Four LCD Segment Enable Registers (LCDSE3:LCDSE0)
• 32 LCD Data Registers (LCDDATA31:LCDDATA0)
The LCDCON register, shown in Register 2-1, controls the overall operation of the module. Once
the module is configured, the LCDEN (LCDCON<15>) 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 LCDPS register, shown in Register 2-2, configures the LCD clock source prescaler and the
type of waveform: Type-A or Type-B. For details on these features, see Section 4.0 “LCD Clock
Source Selection”, Table 14-1 and Section 10.0 “LCD Waveform Generation”.
