16.4.1.62 Offset 110h: CORERRSTS - Correctable Error Status Register
The Correctable Error Status register reports the status of individual error sources on
the PCI Express* device. An individual error status bit that is set indicates that a
particular error occurred. Software may clear an error status bit by writing a ‘1’ to the
bit location. These bits are sticky through reset.
