Result
< 2.9
The device automatically reconfigures itself to work in 2.7 V mode
of operation.
> 2.9 or < 3.10
This range is not recommended for CapSense usage.
< 2.45 V
The scanning for CapSense parameters shuts down until the
voltage returns to over 2.45 V.
> 3.10
The device automatically reconfigures itself to work in 3.3 V mode
of operation.
< 2.4 V
The device goes into reset.
< 4.73 V
The scanning for CapSense parameters shuts down until the
voltage returns to over 4.73 V.
