12. Pin V_DD must not be used for any external supply
13. The RAM content will not be altered above this voltage.
14. External resistance value seen from pin SWI or HW, including 1 kW series resistor. For the switch OPEN, the maximum allowed leakage
current is represented by a minimum resistance seen from the pin.
