lpuart wakeup vlps

Hi.  It is unclear to me as to whether the lpuart can be used to wake-up from vlps mode.  I am using the MK22f512xxx MCU and in section 48.1.2.1 it states that "the LPUART will remain functional during Stop mode.  The LPUART can generate an interrupt to casue a wakeup from stop mode."

 

But, I thought that wakeup's must occur through LLWU sources (I don't think the LLWU has LPUART as a wake-up source). 

 

Can someone explain how I can enable the LPUART interrupt to wake from VLPS mode?
