Cant wakeup KL26Z from LLS

Discussion created by Maximilian Niedernhuber on Nov 22, 2016

Hello,

I cant wake up my KL26Z from LLS mode.

 

I configured the LLWU with ...

  LLWU_SetExternalWakeupPinMode(LLWU,8,kLLWU_ExternalPinFallingEdge);
  LLWU_SetExternalWakeupPinMode(LLWU,7,kLLWU_ExternalPinFallingEdge); 
  PORT_SetPinInterruptConfig(PORTC, (1<<4) | (1<<3) , kPORT_InterruptFallingEdge);
  NVIC_EnableIRQ(LLWU_IRQn);

 

And enter the LLS with ...

  SMC_SetPowerModeLls(SMC);

 

I push a button to cause a falling edge on PTC4/LLWU_P8 but nothing happends.

 

What is wrong? Why I cant wake the MCU from sleep mode?

 

I hope someone can help me.

 

Thanks a lot and best regards,

 

Maximilian
