PEX_UNIT_NERR[7:2] - PCI Express Next Unit Error Register
This register records the occurrence of subsequent 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 next unit errors are sent to the Coherency Engine
where the errors are further recorded and appropriate interrupts are generated through
ERR pins.
PEX_SSERR[7:2,0]: PCI Express Stop and Scream Error Register
This register records the occurrence of stop and scream error due to data poisoning.
