The AXI Base Address Translation Configuration Registers and their offsets are shown in Table: AXI Base Address Translation Configuration Registers and the register bits are described in Table: AXI Base Address Translation Configuration Register Bit Definitions . This set of registers can be used in two configurations based on the top-level parameter C_AXIBAR_AS_n . When the BAR is set to a 32-bit address space, then the translation vector should be placed into the AXIBAR2PCIEBAR_nL register where n is the BAR number. When the BAR is set to a 64-bit address space, then the most significant 32 bits are written into the AXIBAR2PCIEBAR_nU and the least significant 32 bits are written into AXIBAR2PCIEBAR_nL. These registers are only included if C_INCLUDE_BAR_OFFSET_REG = 1.
