int ScuWdtIntrExample ( XScuGic *  IntcInstancePtr,
XScuWdt WdtInstancePtr,
u16  WdtDeviceId,
u16  WdtIntrId 
)

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
IntcInstancePtris a pointer to the instance of the XScuGic driver.
WdtInstancePtris a pointer to the instance of XScuWdt driver.
WdtDeviceIdis the Device ID of the XScuWdt device.
WdtIntrIdis the Interrupt Id of the XScuWdt device.
Returns
XST_SUCCESS if successful, otherwise XST_FAILURE.
Note
None.
