23 MVIO - Multi-Voltage I/O

The Multi-Voltage I/O (MVIO) feature allows a subset of the I/O pins to be powered by a different I/O voltage domain than the rest of the I/O pins. This eliminates the need of having external level shifters for communication or control of external components running on a different voltage level. The MVIO-capable I/O pads are supplied by a voltage applied to the V_DDIOx power pin(s), while the regular I/O pins are supplied by the voltage applied to the V_DD device power pin(s). The MVIO pins on the V_DDIOx power domain are capable of the same digital behavior as regular I/O pins on V_DD power domain like GPIO, serial communication, and PPS functionality. However, the MVIO pins do not support analog inputs or outputs.
