STM32G0x1 external interrupt from PE possible?

[JOtru.1]

My target device is a STM32G0B1VE which has PE but according to RM0444 Reference manual for STM32G0x1 chips the description of EXTI_EXTICRx register says that combination for PE is not present (reserved). Is it really no possible to use PE for an external interrupt? I don't have hardware yet so I cannot test it.

Probably the RM was written when there weren't any chips with a GPIOE and wasn't fully updated. I would be surprised if it didn't work. I don't have a chip to test.

I have the same opinion, STM32G0B1 and STM32G0C1 are the latest devices from the line. Also older IDEs doesn't support them so I suppose the RM is probably outdated in this way.

Hello @JOtru.1​ and welcome to the Community :)

I confirm that Port E is set to enter the EXTI, and the RM should be fixed.

Thank you for your contribution and spotting this out.
