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. Segments S0 through S3 are disabled when the LCD charge pump feature is enabled (LCDCPEN = 1) and cannot be used together
with the LCD charge pump. In addition, when using segments S0 through S3 with an external LCD voltage supply, VLCD ≤ AVCC.
4. Connecting an actual display will increase the current consumption depending on the size of the LCD.
