int ScuTimerIntrExample	(	XScuGic *	IntcInstancePtr,
		XScuTimer *	TimerInstancePtr,
		u16	TimerDeviceId,
		u16	TimerIntrId
	)

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

Parameters

IntcInstancePtr	is a pointer to the instance of XScuGic driver.
TimerInstancePtr	is a pointer to the instance of XScuTimer driver.
TimerDeviceId	is the Device ID of the XScuTimer device.
TimerIntrId	is the Interrupt Id of the XScuTimer device.

Returns

XST_SUCCESS if successful, otherwise XST_FAILURE.

Note

None.
