Note 1:
When the USB module is enabled, VUSB should be provided 3.0V-3.6V while VDD must be 2.35V. When the USB
module is not enabled, the wider limits shaded in grey apply. VUSB should be maintained  VDD, but may optionally
be high-impedance (without external pull-down) when the USB module is not in use.

2:
VDD and VDDCORE must be maintained so that VDDCORE  VDD.
When the USB module is enabled, VUSB should be provided 3.0V-3.6V while VDDCORE must be 2.35V. When
the USB module is not enabled, the wider limits shaded in grey apply. VUSB should be maintained  VDD, but
may optionally be high-impedance (without external pull-down) when the USB module is not in use.
