KL82 VLLS low power modes

Hello,

I am trying to use VLLS mode 1 to implement a low power wakeup. For my wakeup sources, I am using an input pin, and the LPTMR0 set for 15 seconds. The device goes to sleep, and if I toggle the input pin, the device wakes up just fine, and eventually goes back to sleep. If I wait 15s for the LPTMR0 to expire, the device wakes up (I can see a jump in current consumption) but the device is in an unknown state, and can only be restarted by cycling power.

Am I correct in assuming that the VLLS1 can support wake up on pin, and wake up on module together? The provided example in the SDK(power mode switch) will only do one or the other.

I have modelled my code like the SDK example, except I have enabled 2 wakeup sources as mentioned above.

Any insight on this would be appreciated.
