PCIe x4 connector above the Communication Processor (PCI) connector on a TMU-520

PCIe

Bus, resembling Conventional PCIe x4 1.0, partly connected to South Bridge, with 200 exposed pads.
Can be activated by setting the Repository Node sys.lv1.iosys.pciex to 1 (in sysctl.txt). The PCIe MMIO address space can be extended to 1GB by setting sys.lv1.large_pciex to 1.
