Supply-Application in 3.3V environment
Supply-Application in 5V environment
*) When operating in a 5V environment, the voltage-drop across the voltage
regulators 5 Æ 3.3V has to be limited, to keep the regulators in a safe
operating range. Resistive or capacitive loads (in excess to the scheme
shown above) on pins VDDA and VDDD are not recommended.
