This additional Multi-Voltage I/O (MVIO) power supply input pin and corresponding grounding pin must be treated the same way as any other power supply pin pair: By connecting a separate decoupling capacitor at the shortest possible trace distance from pins. If there is more than one MVIO power supply pin, each supply pin and its corresponding ground pin must have a decoupling capacitor.
The following figure shows the recommendation for connecting a power supply to the VDDIO2 pin(s) of the device.
