2. If the device is in 3.3V mode of operation and the operating voltage drops below 3.02V, the device automatically reconfigures itself to work in 2.7V mode of operation.
3. If the device is in 2.7V mode of operation and the operating voltage drops below 2.45V, the scanning for Capsense parameters shuts down until the voltage returns to
4. If the device is in 2.7V mode of operation and the operating voltage rises above 3.02V, the device automatically reconfigures itself to work in 3.3V mode of operation.
5. If the device is in 5.0V mode of operation and the operating voltage drops below 4.73V, the scanning for Capsense parameters shuts down until the voltage returns to
6. Powering up in the 3.6V to 4.75V range is not supported by Capsense Express. The device initializes to the 5.0V parameters but does not enable Capsense scanning
