Maximum Link Width Default Value for Different PCI Express* Ports
Table 56, “Maximum Link Width Default Value for Different PCI Express* Ports”
various combining options for PCI Express* ports. When ports combine, the control
registers for the combined port revert to the lower numbered port. Thus when ports 2
and 3 are combined, the combined x8 port is accessed through port 2 control registers.

Ext_Synch: Extended Synch
This bit when set forces the transmission of 4096 FTS ordered sets in the L0s
state followed by a single SKP ordered set prior to entering the L0 state, and
the transmission of 1024 TS1 ordered sets in the L1 state prior to entering the
Recovery state. This mode provides external devices (e.g., logic analyzers)
monitoring the Link time to achieve bit and Symbol lock before the Link enters
the L0 or Recovery states and resumes communication.
