PEX_UNIT_FERR[7:2, 0] - PCI Express First Unit Error Register
This register records the occurrence of the first unit errors that are specific to this PCI
Express port caused by external activities. For example, VPP error due to a
malfunctioning port on the SMBUS that did not receive acknowledge due to a PCI
Express hot-plug event. The unit errors are sent to the Coherency Engine to classify as
to which port cluster it came from ports 2-3 or ports 4-7 and the errors are recorded in
Coherency Engine and appropriate interrupts generated through ERR pins.
