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.
