**     Description :
**         When a kbi interrupt occurs this event is called (only
**         when the bean is enabled - <Enable> and the events are
**         enabled - <EnableEvent>). This event is enabled only if a
**         <interrupt service/event> is enabled.
**     Parameters  : None
**     Returns     : Nothing
