4.3.10. Correctable Internal Error Status Register

This register reports the status of the internally checked errors that are correctable. When these specific errors are enabled by the Correctable Internal Error Mask register, they are forwarded as Correctable Internal Errors as defined in the PCI Express Base Specification 3.0. This register is for debug only. Use this register to observe behavior, not to drive custom logic.
