Pericom Semiconductor
Other than the PCI 2.3 compatible configuration space header, the Switch also implements PCI
express extended configuration space header, which includes advanced error reporting, virtual channel,
and power budgeting capability registers. The following table details the allocation of the register
fields of PCI express extended capability space header. The first extended capability always begins at
offset 100h with a PCI Express Enhanced Capability header and the rest of capabilities are located at
an offset greater than 0FFh relative to the beginning of PCI compatible configuration space.
