  File Name:
    exceptions.c

  Summary:
    This file contains a function which overrides the default _weak_ exception
    handlers provided by the interrupt.c file.

  Description:
    This file redefines the default _weak_  exception handler with a more debug
    friendly one. If an unexpected exception occurs the code will stop in a
    while(1) loop.
