> @fjmolinas Ah, so it is not application specific? I mean could a specifically crafted application/configuration increase or reduce the number of interrupts ?

Yes and No, you could but that would mean meddling with the `vectors.c` files. e.g.:

https://github.com/RIOT-OS/RIOT/blob/7a264b2af3391fe885dfeb5eacfb2697190c107a/cpu/stm32f4/vectors.c#L141-L147

When the cpu was ported a specific amount of interrupts where defined. If another new peripheral is added that could mean adding a new interrupt, that maybe wasn't added before. But as I understand by looking at the code, even if not used the vector is defined and therefor included in the vector table.

So for me it is not application specific, but CPU specific.
