cfg_wrreq_flr_vld	O	Configuration Write Request FLR Valid: Shows a 1-cycle pulse when a CfgWr Request TLP to the FLR bit field is received from the PCI Express link.
cfg_wrreq_msi_vld	O	Configuration Write Request MSI Valid: Shows a 1-cycle pulse when a CfgWr Request TLP to the MSI bit field is received from the PCI Express link.
cfg_wrreq_msix_vld	O	Configuration Write Request MSIX Valid: Shows a 1-cycle pulse when a CfgWr Request TLP to the MSIX bit field is received from the PCI Express link.
cfg_wrreq_bme_vld	O	Configuration Write Request BME / Interrupt Disable Valid: Shows a 1-cycle pulse when a CfgWr Request TLP to either the BME bit field or the Interrupt Disable bit field is received from the PCI Express link.
cfg_wrreq_vfe_vld	O	Configuration Write Request VFE Valid: Shows a 1-cycle pulse when a CfgWr Request TLP to the VF Enable bit field is received from the PCI Express link.
cfg_wrreq_func_num[15:0]	O	Configuration Write Request Function Number: Shows the Function ID for 1 cycle corresponding to the wrreq valid when a CfgWr Request TLP is received from the PCI Express link.
cfg_wrreq_out_value[3:0]	O	Configuration Write Request Output Value: Shows a 1-cycle pulse of the value corresponding to the wrreq valid when a CfgWr Request TLP is received from the PCI Express link. When FLR-Vld is asserted: [0]: flr value When MSI-Vld is asserted: [3:1]: msi_mmenable[2:0] value [0]: msi_enable value When BME-Vld is asserted: [3]: interrupt_disable write byte enable [2]: interrupt_disable value [1]: bus_master_enable write byte enable [0]: bus_master_enable value When VFE-Vld is asserted: [0]: vf_enable value When MSIX-Vld is asserted: [1]: msix_mask value [0]: msix_enable value
cfg_perfunc_out[23:0]	O	Per-Function Output: Status. [0] Bus Master Enable [1] MSIX Enable [2] MSIX Mask [3] Transactions Pending [4] FLR In Progress [5] ATS Control [8:6] For PF: Power State[2:0] [9] For PF: Memory Space Enable [10] For PF: 10-Bit Tag Requester Enable [11] For PF: MSI Enable [14:12] For PF: MSI mmenable[2:0] [15] For PF: IO Space Enable [16] For PF: INTx Disable [17] For PF: RCB Status [18] For PF: Atomic Requester Enable [19] For PF: PASID Enable [20] For PF: PASID Exec Permission Enable [21] For PF: PASID Privil Mode Enable [23:22] For PF: PRI Control
cfg_perfunc_vld	O	Per-Function Output Valid: When asserted, indicates the Per-Function Input Request has been received and the cfg_perfunc_out contains valid output data.
cfg_perfunc_func_num[15:0]	I	Per-Function Function ID Input Request: Valid entries 16'h0000-16'h100F for Function IDs from 0 to 15 (PFs) and 16 to 4111 (VFs). Values 16'h1010-16'hFFFF are reserved.
cfg_perfunc_req	I	Per-Function Input Request: The user application asserts this input to request status of the cfg_perfunc_func_num Function ID. This input must be held asserted until cfg_perfunc_vld is asserted indicating the request has been received.
