Hi, I want to ask if its possible to use the same ISR for various interrupts sources, as I want to implement a "OS like" function that handles all the interrupts and jumps into the corresponding user ISR performing different privilege/stack adjustments.
I dont know if this is possible and if there is a way to know the specific interrupt source that caused the interrupt inside the same function.
Thanks!! All comments would be appreciated
Yes - if you look at many implementations, you will see that they use the same default handler for all interrupts.

Probably the easiest way is to have a separate ISR for each interrupt, and that ISR passes source info, etc, to your "common" handler.
__get_IPSR() from the interrupt handler will give you an integer indicating the interrupt number (1 is Reset, 16 is the first Programmable interrupt...)
Thanks. This is what i was looking for
