EXTI limits for STM32L562

Leroy3 · ‎2023-12-04

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?

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
