4.3.9. Uncorrectable Internal Error Mask Register

This register controls which errors are forwarded as internal uncorrectable errors. With the exception of the configuration errors detected in CvP mode, all of the errors are severe and may place the device or PCIe link in an inconsistent state. The configuration error detected in CvP mode may be correctable depending on the design of the programming software.
