V
powering the LCD module using V
provides recommendations regarding configuration of the VSUPPLY[1:0] bit field when using both 3-V
and 5-V LCD panels.
24.4.5
During a reset, the LCD module system is configured in the default mode. The default mode includes the
following settings:
24.4.6
When an LCD module frame-frequency interrupt event occurs, the LCDIF bit in the LCDS register is
asserted. The LCDIF bit remains asserted until software clears the LCD-module-frame-frequency
interrupt. The interrupt can be cleared by software writing a 1 to the LCDIF bit.
If both the LCDIF bit in the LCDS register and the LCDIEN bit in the LCDC1 register are set, an LCD
interrupt signal asserts.

This section provides a recommended initialization sequence for the LCD module and also includes
initialization examples for several LCD application scenarios.
