Uncorrectable Error Status
The Uncorrectable Error Status register reports error status of individual uncorrectable error sources on
a PCIe device. An individual error status bit that is set to 1b indicates that a particular error occurred;
software can clear an error status by writing a 1b to the respective bit.

Uncorrectable Error Mask
The Uncorrectable Error Mask register controls reporting of individual uncorrectable errors by device to
the host bridge via a PCIe error message. A masked error (respective bit set in mask register) is not
reported to the host bridge by an individual device. Note that there is a mask bit per bit of the
Uncorrectable Error Status register.
