KL25 using LLWU: crazy microcontroller

Hi, I put my kl25 in LLS mode, and I config LPTMR0 (clocked by LPO) as wake-up source, so I have two class of interrupt to config. I noted this: if the priority of LLWU is bigger than LPTMR0, the micro goes to "loop" in Cpu_INT_LLWInterrupt, it seems LLWU_F3_MWUF0 never is deleted, so it enters and exits continuously. But  if the priority of LLWU is smaller than LPTMR0 all works.

Very very strange.

Any idea?

 

Thank you.
