Is it possible to break out of a function after X amount of time has passed?

[JWall40]

I have a function at the start of my main loop that is updating some local buffers from an ethernet interface.

The problem is, sometimes this hangs and takes about 50x the amount of time it should and disrupts other parts of my program. I'd like to create something which breaks out of this function if, for example, 100uS has passed. 

Is this possible on the nios2 processor? I guess if so, I would first need to implement a timer peripheral, but I'm not sure how I could use this to break the function call and return to outside of the function.

Any suggestions are much appreciated. Thanks for reading

Hi @JWall40,

Thank you for posting in Intel community forum and hope all is well.
If I understand your doubts correctly, you can look into using the internal timer core with irq enable for your purpose.

More details can be found here in explaining the behavior and functions.
And to implement it, perhaps you can refer to the started steps by step example here.
Hope that clarify your doubts.
