Integrated I/O (IIO) Configuration Registers
14.2.103 XPCOREDMASK
XP Correctable Error Detect Mask
This register masks other correctable errors from causing the associated 
XPCORERRSTS status bit to be set.
14.2.104 XPGLBERRSTS
XP Global Error Status
This register captures a concise summary of the error logging in AER registers so that 
sideband system management software can view the errors independent of the main 
OS that might be controlling the AER errors.
14.2.105 XPGLBERRPTR

pcie_aer_correctable_error:
A PCIe* correctable error (ERR_COR message received from externally or 
through a virtual ERR_COR message generated internally) was detected 
anew. Note that if that error was masked in the PCIe* AER, it is not reported 
in this field. Software clears this bit by writing a 1 and at that stage, only 
‘subsequent’ PCIe* unmasked correctable errors will set this bit.Concep-
tually, per the flow of PCI Express Base Spec 2.0 defined Error message 
control, this bit is set by the ERR_COR message that is enabled to cause a 
System Error notification.

pcie_aer_non_fatal_error:
A PCIe* nonfatal error (ERR_NONFATAL message received from externally or 
through a virtual ERR_NONFATAL message generated internally) was 
detected anew. Note that if that error was masked in the PCIe* AER, it is not 
reported in this field. Software clears this bit by writing a 1 and at that stage 
only ‘subsequent’ PCIe* unmasked nonfatal errors will set this bit again.

pcie_aer_fatal_error:
A PCIe* fatal error (ERR_FATAL message received from externally or through 
a virtual ERR_FATAL message generated internally) was detected anew. Note 
that if that error was masked in the PCIe* AER, it is not reported in this field. 
Software clears this bit by writing a 1 and at that stage, only ‘subsequent’ 
PCIe* unmasked fatal errors will set this bit.
