Table 5-12: Uncorrectable Internal Error Status Register
This register reports the status of the internally checked errors that are uncorrectable. When specific errors are
enabled by the

register, they are handled as Uncorrectable Internal
Errors as defined in the PCI Express Base Specification 3.0. This register is for debug only. It should only be used to
observe behavior, not to drive custom logic. The access code RW1CS represents Read Write 1 to Clear Sticky.
