Hi, I'm trying to use all the external interrupts in a project in order to detect the "end of conversion" signals from some sensors I'm using.
I was trying to use EXTINT3 and I have some problems. If I only use EXTINT3 then everything works fine, but if I also use another external interrupt, e.g. EXTINT2, then I receive interrupts from EXTINT2 in the EXTINT3 handler. I know all GPIO interrupts are connected to EXTINT3, and I guess this has something to do with this problem, but I don't know how to avoid it.
I can't avoid using EXTINT3, any ideas to solve it?
Thanks in advance.
