Correctable Error Mask Register

The correctable 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 5−6 for a complete description of the

PCI Express extended register offset:

114h

Read-only, Read/Write

Default value:

0000 0000h
