/* This file contains default interrupt handlers code for the
   interrupt vector.  All but one of the interrupts are user
   replaceable.

   These interrupt handlers are entered whenever the associated
   interrupt occurs.  All they do is stop the debugger to give the user
   the opportunity to determine where the problem was.
  
   User trap BDM_TRAPNUM (15) is used for semi hosting support.
   If you replace this one, semihosting will cease to function. */
