Custom Instruction-Related Exception Handler
For use outside the debugger, you can register your own instruction-related exception handler which is
called when the break (or any exception) is seen.
On an exception, including overflow, the HAL calls the instruction-related exception handler, passing in
the cause field from the exception register, and the address which caused the exception. At this point, it is
up to you to decide what do.
