EXTI limits for STM32L562

[Leroy3]

STM32CubeIDE does not give me an options to select PE15 as an external interrupt source.

The documentation , RM0438 suggests there are 15 possible external interrupts.  Which is true?

Hello @Leroy3, 

It is possible to select PE15 as GPIO_EXTI15 

Could you share a screenshot of your issue 

[Leroy3]

Yes.  That was my mistake.  Somehow I accidently setup PB1 and PB2 as EXTI instead of outputs.  And didn't notice the possibility to select a pin as an external input source.  Thank-you
