13.1.57 CES—Correctable Error Status Register (PCI Express*—
D28:F0/F1/F2/F3/F4/F5/F6/F7)
Address Offset: 110h–113h Attribute: R/WC
Default Value: 00000000h Size: 32 bits
13.1.58 CEM—Correctable Error Mask Register (PCI Express*—
D28:F0/F1/F2/F3/F4/F5/F6/F7)
Address Offset: 114h–117h Attribute: R/WO
Default Value: 00002000h Size: 32 bits
When set, the corresponding error in the CES register is masked, and the logged error
will cause no action. When cleared, the corresponding error is enabled.
12 Poisoned TLP Severity (PT) — R/W.
0 = Error considered non-fatal. (Default)
1 = Error is fatal.
11:5 Reserved
4 Data Link Protocol Error Severity (DLPE) — R/W.
0 = Error considered non-fatal.
1 = Error is fatal. (Default)
3:1 Reserved
0 Training Error Severity (TE) — R/W. TE is not supported.

13 Advisory Non-Fatal Error Status (ANFES) — R/WC.
0 = Advisory Non-Fatal Error did not occur.
1 = Advisory Non-Fatal Error did occur.
12 Replay Timer Timeout Status (RTT) — R/WC. Indicates the replay timer timed out.
11:9 Reserved
8 Replay Number Rollover Status (RNR) — R/WC. Indicates the replay number rolled over.
7 Bad DLLP Status (BD) — R/WC. Indicates a bad DLLP was received.
6 Bad TLP Status (BT) — R/WC. Indicates a bad TLP was received.
5:1 Reserved
0 Receiver Error Status (RE) — R/WC. Indicates a receiver error occurred.
Bit Description
31:14 Reserved
13 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.
11:9 Reserved
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.
6 Bad TLP Mask (BT) — R/WO. Mask for bad TLP reception.
