Hi,

I would implement a â€œdivide by zero trapâ€� in C program. I know that this trap is different from normal interrupt it has to be finished not with ''iret''.

How it can be done? Could someone give me a simple example?

Thanks a lot.

Read crtbegin.spp file and track the divide by zero ISR

there wont be anything but you can add your function.

but do read the datasheet carefully before that.
