SSID/SSVID
The PES16T4AG2 contains the mechanisms necessary to implement the PCI-to-PCI bridge Subsystem
ID and Subsystem Vendor ID capability structure. However, in the default configuration the Subsystem ID
and Subsystem Vendor ID capability structure is not enabled. To enable the capability, the SSID and SSVID
fields in the Subsystem ID and Subsystem Vendor ID (SSIDSSVID) register must be initialized with the
appropriate ID values. the Next Pointer (NXTPTR) field in one of the other enhanced capabilities should be
initialized to point to this capability. Finally, the Next Pointer (NXTPTR) of this capability should be adjusted
to point to the next capability if necessary.
