(1)

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating

conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltage values are with respect to VSS, USB0_VSSA33, USB0_VSSA, PLL0_VSSA, OSCVSS, RTC_VSS

(3)

Up to a maximum of 24 hours.
