Bit Acronym
Bit Description
Sticky
MTLP
Malformed TLP Status: Malformed TLP errors include:
data payload length issues, byte enable rule violations, and
various other illegal field settings. This bit is sticky through
reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Malformed TLP detected.
ROVF
Receiver Overflow Status: IMCH checks for overflows on
the following upstream queues: posted, non-posted, and
completion. This bit is sticky through reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Receiver Overflow detected.
UEC
Unexpected Completion Status: This bit is set when the
device receives a completion which does not correspond to
any of the outstanding requests issued by that device. This
bit is sticky through reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Unexpected Completion detected.
Completer Abort Status: If a request received violates
the specific programming model of this device, but is
otherwise legal, this bit is set. This bit is sticky through
CA
reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Completer Abort detected.
Completion Timeout Status: The Completion Timeout
timer must expire if a Request is not completed in 50 ms,
but must not expire earlier than 50 µs. When the timer
CT
expires, this bit is set. This bit is sticky through reset.
Y
0 = Cleared by writing a ‘1’ to the bit location.
1 = Completion timeout detected.
Reserved Reserved
PTLP
Poisoned TLP Status: This bit when set indicates that
some portion of the TLP data payload was corrupt. This bit
is sticky through reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Poisoned TLP detected.
Reserved Reserved
DLPE
Data Link Protocol Error Status: This bit is set when an
ACK/NAK received does not specify the sequence number
of an unacknowledged TLP, or of the most recently
acknowledged TLP. This bit is sticky through reset.
0 = Cleared by writing a ‘1’ to the bit location.
1 = Data Link Protocol Error detected.
Reserved Reserved
RTTO
Replay Timer Timeout Status: The replay timer counts
time since the last ACK or NAK DLLP was received. When
the timer expires, this bit is set. This bit is sticky through
system reset.
Y
0 = Cleared by writing a ‘1’ to the bit location.
1 = Replay Timer timeout detected.
