          Args:
            self (JLink): the ``JLink`` instance
  
          Returns:
            A list of ``JLInkMOEInfo`` instances specifying the reasons for which
            the CPU was halted.  This list may be empty in the case that the CPU
            is not halted.
  
          Raises:
            JLinkException: on hardware error.
