Hello,

because of safety reasons I need so trigger an NMI via an external line. Is there any way get this working on the STM32F103VC?

I read the reference manual and the datasheet and didn't find anything helpful for this problem (maybe, I did just look for the wrong info).

I appreciate any help.

Thanks and Regards.

Steve

According to Table 36 in section 8.1.2 (and section 6.2.7) of the STM32F103xx Reference manual

''The RCC Clock Security System (CSS) is linked to the NMI vector.''

I don't think you can directly connect the NMI to an external pin :(
