1) To ensure the stability of the voltage regulators the EVRs must be buffered with ceramic capacitors. Separate
2) Use one Capacitor for each pin.
3) This is the reference load. For bigger capacitive loads, use the derating factors listed in the PAD properties
4) The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output
5) The operating frequency range may be reduced for specific device types. This is indicated in the device
6) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin
7) An overload current (
