1) In case both core power domains are clocked, the difference between the power supply voltages must be less

3) This limitation must be fulfilled under all operating conditions including power-ramp-up, power-ramp-down,
4) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin
5) Not subject to production test - verified by design/characterization.

supply both core power domains, two independent external voltage regulators may not be used. The simplest
possibility is to supply both power domains directly via a single external power supply.

overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the specified
limits. Proper operation under overload conditions depends on the application.
