9.5.2 Initialization Examples
This section provides initialization information for configuration of the LCD. Each example details the
register and bit field values required in order to achieve the appropriate LCD configuration for a given LCD
application scenario. Table 9-21 lists each example and the setup requirements.
These examples illustrate the flexibility of the LCD module to be configured to meet a wide range of application requirements
including:
• clock inputs/sources
• LCD power supply
• LCD glass operating voltage
• LCD segment count
• varied blink modes/frequencies
• LCD frame rate
