          int ScuTimerIntrExample 
          (
          XScuTimer * 
          TimerInstancePtr,

          )
          
        

      





This function tests the functioning of the Cortex A9 Scu Private Timer driver and hardware using interrupts. 


Parameters

  

    
TimerInstancePtris a pointer to the instance of XScuTimer driver. 

    
BaseAddressis the base address of the XScuTimer device.

  

  




Returns
XST_SUCCESS if successful, otherwise XST_FAILURE.


Note
In XSCT/classic flow, DeviceId is used to look up the device configuration.
