14.Pin VDD must not be used for any external supply

15.The RAM content will not be altered above this voltage.

16.External resistance value seen from pin SWI or HW2, including 1 kW series resistor. For the switch OPEN, the maximum allowed leakage

current is represented by a minimum resistance seen from the pin.
