The device automatically reconfigures itself to work in 2.7 V
mode of operation.
This range is not recommended for CapSense usage.
The scanning for CapSense parameters shuts down until the
voltage returns to over 2.45 V.
The device automatically reconfigures itself to work in 3.3 V
mode of operation.
The device goes into reset.
The scanning for CapSense parameters shuts down until the
voltage returns to over 4.73 V.
