1. If the internal voltage regulator is enabled, the minimum voltage is 4.25V instead of 3.0V.
2. CLKOUT is not driven and the device is not accessed.
3. The internal votlage regulator is disabled.
4. These voltage levels apply only when an external clock is connected to XTALIN.
5. Much lower voltage levels are expected when the internal oscillator is used.
6. Not tested. Guaranteed by design.
7. The internal voltage regulator is intended to power only the internal transceivers and one external pull-up.
