## Functions
s32 | XScuGic_Connect (XScuGic *InstancePtr, u32 Int_Id, Xil_InterruptHandler Handler, void *CallBackRef)
| Makes the connection between the Int_Id of the interrupt source and the associated handler that is to run when the interrupt is recognized. More...
void | XScuGic_Disconnect (XScuGic *InstancePtr, u32 Int_Id)
| Updates the interrupt table with the Null Handler and NULL arguments at the location pointed at by the Int_Id. More...
