Uncorrectable Internal Error Mask Register
Table 5-11: 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.
