  Summary:
    Interrupt vectors mapping

  Description:
    This file maps all the interrupt vectors to their corresponding
    implementations. If a particular module interrupt is used, then its ISR
    definition can be found in corresponding PLIB source file. If a module
    interrupt is not used, then its ISR implementation is mapped to dummy
    handler.
