3.17.70 PCI Express Uncorrectable Error Status - ERRUNC_STS

The Uncorrectable Error Status register indicates error detection status of individual

uncorrectable errors on a PCI Express device. An individual error status bit that is set to

“1” indicates that a particular error was detected; software may clear an error status by

writing a 1 to the respective bit.

Note:

All bits in this register are sticky through reset.
