Hi all,

I have to be sure before I will make another step in my project:

Can I wake up the STM32L152 from the STOP mode by any edge on any pin? In other words: can I configure any pin as input to wake up from STOP mode?

According to the reference manual, you can use any EXTI line, if you enable the corresponding interrupt.

There is a difference if you enter with WFI or WFE - see the respective pages 75 + 184 of the ref. manual.

Yes, I saw the manual.

I made test on different pins and only those with additional WKUP function worked properly.
