## Data Structures
struct | XIntc_Config
| This typedef contains configuration information for the device. More...
struct | XIntc
| The XIntc driver instance data. More...

## Macros
Configuration options
These options are used in XIntc_SetOptions() to configure the device.
#define | XIN_SVC_SGL_ISR_OPTION 1UL
#define | XIN_SVC_ALL_ISRS_OPTION 2UL
Start modes
One of these values is passed to XIntc_Start() to start the device.
#define | XIN_SIMULATION_MODE 0
| Simulation only mode, no hardware interrupts recognized. More...
#define | XIN_REAL_MODE 1
| Real mode, no simulation allowed, hardware interrupts recognized. More...
Masks to specify Interrupt Controller Mode
#define | XIN_INTC_NOCASCADE 0 /* Normal - No Cascade Mode */
#define | XIN_INTC_PRIMARY 1 /* Master/Primary controller */
#define | XIN_INTC_SECONDARY 2 /* Secondary Slave Controllers */
#define | XIN_INTC_LAST 3 /* Last Slave Controller */
Mask to specify maximum number of interrupt sources per controller
#define | XIN_CONTROLLER_MAX_INTRS
#define | XINTC_STANDARD_VECTOR_ADDRESS_WIDTH 32U

## Functions
int | XIntc_Initialize (XIntc *InstancePtr, u16 DeviceId)
| Initialize a specific interrupt controller instance/driver. More...
int | XIntc_Start (XIntc *InstancePtr, u8 Mode)
| Starts the interrupt controller by enabling the output from the controller to the processor. More...
void | XIntc_Stop (XIntc *InstancePtr)
| Stops the interrupt controller by disabling the output from the controller so that no interrupts will be caused by the interrupt controller. More...
int | XIntc_Connect (XIntc *InstancePtr, u8 Id, XInterruptHandler Handler, void *CallBackRef)
| Makes the connection between the Id of the interrupt source and the associated handler that is to run when the interrupt is recognized. More...
void | XIntc_Disconnect (XIntc *InstancePtr, u8 Id)
| Updates the interrupt table with the Null Handler and NULL arguments at the location pointed at by the Id. More...
void | XIntc_Enable (XIntc *InstancePtr, u8 Id)
| Enables the interrupt source provided as the argument Id. More...
void | XIntc_Disable (XIntc *InstancePtr, u8 Id)
| Disables the interrupt source provided as the argument Id such that the interrupt controller will not cause interrupts for the specified Id. More...
void | XIntc_Acknowledge (XIntc *InstancePtr, u8 Id)
| Acknowledges the interrupt source provided as the argument Id. More...
XIntc_Config * | XIntc_LookupConfig (u16 DeviceId)
| Looks up the device configuration based on the unique device ID. More...
int | XIntc_ConnectFastHandler (XIntc *InstancePtr, u8 Id, XFastInterruptHandler Handler)
| Makes the connection between the Id of the interrupt source and the associated handler that is to run when the interrupt is recognized.In Cascade mode, connects handler to corresponding Slave controller IVAR/IVEAR register depending on the Id and sets all interrupt sources of the Slave controller as fast interrupts. More...
void | XIntc_SetNormalIntrMode (XIntc *InstancePtr, u8 Id)
| Sets the normal interrupt mode for the specified interrupt in the Interrupt Mode Register. More...
void | XIntc_InterruptHandler (XIntc *InstancePtr)
| Interrupt handler for the driver used when there can be no argument passed to the handler. More...
int | XIntc_SetOptions (XIntc *InstancePtr, u32 Options)
| Set the options for the interrupt controller driver. More...
u32 | XIntc_GetOptions (XIntc *InstancePtr)
| Return the currently set options. More...
int | XIntc_SelfTest (XIntc *InstancePtr)
| Run a self-test on the driver/device. More...
int | XIntc_SimulateIntr (XIntc *InstancePtr, u8 Id)
| Allows software to simulate an interrupt in the interrupt controller. More...
