NOTES:

1. Enabling the internal charge pump with an external capacitor smaller than the minimum specified might damage the device.

2. Refer to the supply current specifications I(LPM3) for additional current specifications with the LCD_A module active.

3. Connecting an actual display will increase the current consumption depending on the size of the LCD.
