22.4 FIIC Controller Registers

The register set contains two interrupt enable registers, two interrupt status registers and an interrupt mode register. The interrupt enable registers do not affect the Cortex-M3 processor NVIC; these are per bit enables of the interrupt routed to the FPGA fabric.

The following table summarizes each of the registers covered by this chapter. The base address of the FIIC block is 0x40006000.
