23.4.1 MVIO Control Register

Note:
  1. Refer to the MVIO VDDIOx Low-Voltage Detect parameters in the "Electrical Specifications" chapter for more information.
  2. When the VDDIOx IO monitor has been disabled using the MODE bit, the associated system level interrupt (VDDIOxRDYIF) will no longer function and should be disabled using the respective interrupt enable bit (VDDIOxRDYIE).
  3. This bit will always read back as '0' when the VDDIOx Low-Voltage detection is disabled (LVD = 0b000), and when the the VDDIOx voltage domain is not ready for use.
