23.4.1 VDDIOxCON

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 monitors have been disabled using the MODE bit, the associated system level interrupts (VDDIOxRDYIF and VDDIOxPORIF) will no longer function and should be disabled using the respective interrupt enable bits (VDDIOxRDYIE and VDDIOxPORIE).
  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.
