Contains required functions for the <aclass="el"href="struct_x_intc.html">XIntc</a> driver for the Xilinx Interrupt Controller. See <aclass="el"href="xintc_8h.html">xintc.h</a> for a detailed description of the driver.<p>
Acknowledges the interrupt source provided as the argument Id. When the interrupt is acknowledged, it causes the interrupt controller to clear its interrupt condition.In Cascade mode, acknowledges corresponding interrupt source of Slave controllers depending on the Id.<p>

Makes the connection between the Id of the interrupt source and the associated handler that is to run when the interrupt is recognized. The argument provided in this call as the Callbackref is used as the argument for the handler when it is called. In Cascade mode, connects handler to Slave controller handler table depending on the interrupt Id.<p>

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 register depending on the Id and sets all interrupt sources of the Slave controller as fast interrupts.<p>

WARNING: The handler provided as an argument will overwrite any handler that was previously connected.
Disables the interrupt source provided as the argument Id such that the interrupt controller will not cause interrupts for the specified Id. The interrupt controller will continue to hold an interrupt condition for the Id, but will not cause an interrupt.In Cascade mode, disables corresponding interrupt of Slave controllers depending on the Id.<p>

Updates the interrupt table with the Null Handler and NULL arguments at the location pointed at by the Id. This effectively disconnects that interrupt source from any handler. The interrupt is disabled also. In Cascade mode, disconnects handler from Slave controller handler table depending on the interrupt Id.<p>

Enables the interrupt source provided as the argument Id. Any pending interrupt condition for the specified Id will occur after this function is called. In Cascade mode, enables corresponding interrupt of Slave controllers depending on the Id.<p>

Starts the interrupt controller by enabling the output from the controller to the processor. Interrupts may be generated by the interrupt controller after this function is called.<p>
It is necessary for the caller to connect the interrupt handler of this component to the proper interrupt source. This function also starts Slave controllers in Cascade mode.<p>
