Uncorrectable Error Mask Register
The uncorrectable error mask register controls the reporting of individual errors as they occur. When a mask
bit is set to 1b, the corresponding error status bit is not set, PCI Express error messages are blocked, the
header log is not loaded, and the first error pointer is not updated. See Table 5−3 for a complete description
of the register contents.
