6.1
PI7C9X111SL supports Type-0 and Type-1 configuration space headers and Capability ID of 01h (PCI power
management) to 10h (PCI Express capability structure).
With pin REVRSB = 0, device-port type (bit [7:4]) of capability register will be set to 7h (PCI Express-to-PCI).
When pin REVRSB = 1, device-port type (bit [7:4]) of capability register will be set to 8h (PCI-to-PCI Express
bridge).
PI7C9X111SL supports PCI Express capabilities register structure with capability version set to 1h (bit [3:0] of
offset 02h).
PI7C9X111SL supports capability pointer with PCI power management (ID=01h), PCI bridge sub-system vendor
ID (ID=0Dh), PCI Express (ID=10h), vital product data (ID=03h), and message signaled interrupt (ID=05h). Slot
identification (ID=04h) is off by default and can be turned on through configuration programming.
