/* Interrupt Tasks Routine Pointer

  Summary:
    Pointer to an interrupt-handling "Tasks" routine.

  Description:
    This data type defines a pointer to an interrupt-handling "Tasks" routine.
    The form of a tasks routine is as follows:
    
       void My_Tasks ( SYS_MODULE_OBJ object );
    
    Where "MyTasks" is the name of the tasks routine and object is a Handle 
    to the module instance.
    
  Remarks:
    "Tasks" is normally defined by a device driver, middleware, or system
    layer.
    
    The term Interrupt Service Routine (ISR) is used for the "raw" ISR code 
    that is either located directly at the interrupt vector address or whose 
    address is loaded from the interrupt vector.  The term "Tasks" routine is 
    used to identify the driver-specific routine that is called by the actual
    ISR to perform the tasks necessary to handle and clear the interrupt.

  Description:
    This function registers an Interrupt "Tasks" Routine for the specified
    interrupt source or trap).
  Conditions:
    SYS_INT_Initialize must have been called.
  Input:
    source -  Identifier for the desired interrupt source
    tasks -   Pointer to the tasks routine
    object -  Handle to the module instance
  Return:
    None.
  Example:
    <code>
    SYS_INT_Initialize();
    SYS_INT_DynamicRegister(MY_DRIVER_INTERRUPT_SOURCE, DRV_MYDEV_Tasks, MyObject);
    </code>
  Remarks:
    This routine only generates executable code when a driver is configured
    to register dynamically its "Tasks" routine with the system interrupt
    service. However, it should be called even if the ISR-to-source
    association is defined statically at compile time to maintain source
    code compatibility. A device driver normally registers its own ISR from
    its initialization routine.
    
    In the example code, the macros MY_DRIVER_INTERRUPT_SOURCE would be
    defined in the appropriate configuration header, which would be
    included by the driver source file where the "DRV_MYDEV_Tasks" routine
    and the MyParam data would be defined.
    
    It is safe to call this routine without first calling
    SYS_INT_DynamicDeregister, even if a previous ISR has been registered.
    The effect will be that the new ISR supplants the old one.
