• The arg element is a generic argument that is passed to the plugged function as its only parameter. The default value is 0.
• The enableInt element determines whether the interrupt should be enabled in the IER by create.
• The maskSetting element defines the dispatcherAutoNestingSupport behavior of the interrupt.
