5.6.1. Uncorrectable Internal Error Mask Register

Table 51.  Uncorrectable Internal Error Mask Register The Uncorrectable Internal Error Mask register controls which errors are forwarded as internal uncorrectable errors. With the exception of the configuration error detected in CvP mode, all of the errors are severe and may place the device or PCIe link in an inconsistent state. The configuration error detected in CvP mode may be correctable depending on the design of the programming software. The access code RWS stands for Read Write Sticky meaning the value is retained after a soft reset of the IP core.
