Correctable Error Mask Register @0x114
The mask bits in this register control the reporting of correctable errors. For each error type in the Correctable Error Status Register, there is a corresponding bit in this register to mask its reporting. When a mask bit is set, the occurrence of the error is not reported to the Root Complex (by a PCI Express error message). The individual bits of the mask register are described below. The bits marked RW can also be written from the local management bus.
