Active/Sleep Mode
The Active/Sleep Mode control changes the operating mode of the LDC1101; pressing the button toggles
between Sleep mode and Active mode. While in Sleep Mode the device can be configured with the
desired settings; it is recommended to make all device configuration changes in Sleep Mode.
In Active mode, the device is continuously converting and any enabled output plots are updated.

Sensor Configuration
The CLKIN Frequency should be set to 12MHz unless the frequency is changed using an external clock
source.
The default sensor comes with a sensor capacitance of 390pF; if the sensor capacitance is physically
changed then modify the Sensor Capacitor control setting to match the new capacitor value.
