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.
IntcInstancePtr | is a pointer to the instance of the XScuGic driver. |
WdtInstancePtr | is a pointer to the instance of XScuWdt driver. |
WdtDeviceId | is the Device ID of the XScuWdt device. |
WdtIntrId | is the Interrupt Id of the XScuWdt device. |
