int ScuWdtIntrExample	(	XScuWdt *	WdtInstancePtr,
		UINTPTR	BaseAddress
	)

This function tests the functioning of the Scu Private WDT driver and hardware in Timer mode using interrupts.

After one expiration of the timeout interval, an interrupt is generated and the Event flag bit is set in the watchdog interrupt status register.

Parameters

WdtInstancePtr	is a pointer to the instance of XScuWdt driver.
BaseAddress	contains the base address of the device

Returns

XST_SUCCESS if successful, otherwise XST_FAILURE.

Note

None.
