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, V

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