The VDDIO pin provides a secondary input allowing some I/Os to be powered by a source other than LDO_3V3. The default state is power from LDO_3V3. The memory stored in the flash will configure the I/O’s to use LDO_3V3 or VDDIO as a source and application code will automatically scale the input and output voltage thresholds of the I/O buffer accordingly. See I/O Buffers for more information on the I/O buffer circuitry. See Table 11-1 for the recommended external capacitance on the VDDIO pin.
