Advisory Non-Fatal Error Mask (ANFEM) — R/WO.
0 = Does not mask Advisory Non-Fatal errors.
1 = Masks Advisory Non-Fatal errors from (a) signaling ERR_COR to the device control
register and (b) updating the Uncorrectable Error Status register.
This register is set by default to enable compatibility with software that does not
comprehend Role-Based Error Reporting.
NOTE: The correctable error detected bit in device status register is set whenever the
Advisory Non-Fatal error is detected, independent of this mask bit.
12 Replay Timer Timeout Mask (RTT) — R/WO. Mask for replay timer timeout.

8 Replay Number Rollover Mask (RNR) — R/WO. Mask for replay number rollover.
7 Bad DLLP Mask (BD) — R/WO. Mask for bad DLLP reception.
