 System Interrupts File



  File Name:

    system_interrupt.c



  Summary:

    Raw ISR definitions.



  Description:

    This file contains a definitions of the raw ISRs required to support the

    interrupt sub-system.



  Summary:

    This file contains source code for the interrupt vector functions in the

    system.



  Description:

    This file contains source code for the interrupt vector functions in the

    system.  It implements the system and part specific vector "stub" functions

    from which the individual "Tasks" functions are called for any modules

    executing interrupt-driven in the MPLAB Harmony system.



  Remarks:

    This file requires access to the systemObjects global data structure that

    contains the object handles to all MPLAB Harmony module objects executing

    interrupt-driven in the system.  These handles are passed into the individual

    module "Tasks" functions to identify the instance of the module to maintain.
