23.3.2 Power Sequencing
When the VDDIOxMD bit is correctly configured as explained in the previous section, the
MVIO domains are designed to be independent of one another, thus allowing the
VDD and VDDIOx voltages to ramp up/down independently. The
following power sequencing scenarios are covered:
- VDD ramps up before VDDIOx
- VDDIOx ramps up before VDD
- VDD loses and regains power while VDDIOx is stable
- VDDIOx loses and regains power while VDD is stable
