System Error on Fatal Error Enable (SFE) — R/W.
0 = Disable. An SERR# will not be generated.
1 = Enable. An SERR# will be generated, assuming CMD.SEE (D28:F0/F1/F2/F3/F4/
System Error on Non-Fatal Error Enable (SNE) — R/W.
0 = Disable. An SERR# will not be generated.
1 = Enable. An SERR# will be generated, assuming CMD.SEE (D28:F0/F1/F2/F3/F4/
System Error on Correctable Error Enable (SCE) — R/W.
0 = Disable. An SERR# will not be generated.
1 = Enable. An SERR# will be generated, assuming CMD.SEE (D28:F0/F1/F2/F3/F4/

PME Pending (PP) — RO.
0 = Indicates no more PMEs are pending.
1 = Indicates another PME is pending (this is implicit because of the definition of this bit
PME Status (PS) — R/WC.
0 = PME was not asserted.
1 = PME was asserted by the requestor ID in RID. Subsequent PMEs are kept pending
PME Requestor ID (RID) — RO. This field indicates the PCI requestor ID of the last
PME requestor. The value in this field is valid only when PS is set.
F5:60h, bit 16) is in a set state (either due to a 0 to 1 transition, or due to this bit
being set with RSTS.IS already set).
F5:04, bit 8) is set, if a fatal error is reported by any of the devices in the hierarchy
of this root port, including fatal errors in this root port.
F5:04, bit 8) is set, if a non-fatal error is reported by any of the devices in the
hierarchy of this root port, including non-fatal errors in this root port.
F5:04, bit 8) if a correctable error is reported by any of the devices in the hierarchy
of this root port, including correctable errors in this root port.

appropriately. The PME pending bit is cleared by hardware if no more PMEs are
pending.
