Jesper, thanks for your help...

You are absolutely right. This is the behavior that I am seeing.
But, the "breakpoint" reached is inside of the "ctrlc_isr",
so the same "line number, file name" is reported. I'd like to
change that behavior and add the breakpoint to the address
of the interrupted routine.
