how to wakeup kl16 from vlps using uart0

Hi All,


How do you wake up a KL16 from VLPS (Very Low Power Stop) mode using UART0?

We are using a MKL16Z128VFT4 and according to the reference manual, UART0  is in Async operation (fully functional provided you are still clocking it) in VLPS. Can I clock it using the LPO since it is the only clock available and still ON during VLPS mode?


Any idea is welcomed and will be much appreciated.
