LLWU + PORT interrupt

Hello,

I have configured single pin both to generate interrupt (in PORTx_PCRn register) and to wake MCU (MK20DN512VLL10) from LLS (LLWU_PEn register).

 

I have enabled both interrupts in NVIC.

 

When MCU wakes up, will both interrupt handlers (LLW_IRQHandler and PORTx_IRQHandler) be invoked? Or only  LLW_IRQHandler?

 

When MCU wakes up, are PORTx_IRQHandler and LLW_IRQHandler invoked according to their interrupt priority (higher priority first)?

 

Does clearing of ISF bit in PORTx_PCRn also clear corresponding bit in LLWU_Fx?

 

Does clearing bit in LLWU_Fx also clear corresponding ISF bit in PORTx_PCRn?


Best regards

 

Martin
