can external interrupt be shared?

[precisionman]

I have used all external interrupt sources:

   MCF5282_INT_EPORT1,          //  1 Edge port flag 1
   MCF5282_INT_EPORT2,          //  2 Edge port flag 2
   MCF5282_INT_EPORT3,          //  3 Edge port flag 3
   MCF5282_INT_EPORT4,          //  4 Edge port flag 4
   MCF5282_INT_EPORT5,          //  5 Edge port flag 5
   MCF5282_INT_EPORT6,          //  6 Edge port flag 6

I need one more. I mux with one of the current source(port 2). I know which one is triggered, and in my ISR, I check and set the callback function to serve the proper interrupt. However, the trick is how to re-enable interrupt vector, so i wont miss ohter interrupt nor get hung up. My system hangs up after few minutes (no more interrupt from this port)

thx.

Hello precisionman,

can you be more specific with your ISR problem? What's your ISR routine now, at least highlight the step your code does in the ISR. How do you set the callback, using lwevent? direct function call inside the ISR?
