Supply Voltage to AVSS
or DVss (AVDD, DVDD)
Stresses above those listed under Absolute Maximum Rat-
ings may cause permanent device failure. Functionality at or
above these limits is not implied. Exposure to Absolute Maxi-
mum Ratings for extended periods may affect device reliabil-
ity. Programming conditions may differ.
