Interrupt processing registers are shared between AXI Bridge and AXI DMA. In AXI Bridge mode when MSI-X Capabilities is selected, 64 KB address space from the BAR0 is reserved for the MSI-X table. By default, register space is allocated in BAR0. You can select register space in a different BAR, from BAR1 to BAR5, by using the CONFIG.bar_indicator {BAR0} Tcl command. This option is valid only when MSI-X Capabilities option is selected. There is no allocated space for other interrupt options.
