Hi All,
I make the MCU MK60FN1M0VLQ12 to LLS mode and use the following function to set the wake up timer.
But every time, after I call the set_timer_wakeup fucntion, it will enter the timer_wakeup_isr intermediately.
And I put a LED_Toggle command after enter_lls() , it never run that instruction. It seems the wake up timer does not wake up the MCU.
Any ideas about this?
Thank you.
