The LCD driver module is a CMOS charge pump voltage inverter that is designed for low-voltage, low-power operation. The LCD driver module is designed to generate the appropriate waveforms to drive multiplexed numeric, alpha-numeric, or custom LCD panels. Depending on LCD module hardware and software configuration, the LCD panels can be either 3 Vor 5 V and be driven by different waveform modes. The LCD module also has several timing and control settings that can be software configured depending on the applications requirements. Timing and control consists of registers and control logic for:

• LCD frame frequency

• Duty cycle select

• Frontplane/backplane select and enable

• Blink modes and frequency

• Operation in low-power modes

Peripheral Initialization Components provide a low-level hardware approach to initialize registers of the peripheral module. They are intended for experienced users.
