The device should not be op- erated at these limits. The parametric values defined in the Electrical Charac- teristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for ac- tual device operation. Note 2:The A port unused pins (inputs and I/O’s) must be held HIGH or LOW. They may not float.
