Received flow control DLLP virtual channel ID parameter. This
signal reports the virtual channel ID of the received flow control
DLLP:
●
●
●
●
This signal also indicates the type of PM DLLP received.
Received nullified transaction layer packet. This signal indicates
that a nullified transaction layer packet has been received.
Received transaction layer packet with LCRC error. This signal
reports that a transaction layer packet has been received that
contains an LCRC error.
Received valid transaction layer packet. This signal reports that
a valid transaction layer packet has been received that contains
the correct sequence number. Such a transaction layer packet
is transmitted to the application layer.
Received duplicated transaction layer packet. This signal
indicates that a transaction layer packet has been received that
has already been correctly received. Such a transaction layer
packet is silently discarded.
Received erroneous transaction layer packet. This signal
indicates that a transaction layer packet has been received that
contains a valid LCRC but a non-sequential sequence number
(higher than the current sequence number).
Data link layer framing error detected. This signal indicates that
received data cannot be considered as a DLLP or transaction
layer packet, in which case a Receive Port error is generated
and link retraining is initiated.
transaction layer packet count in retry buffer. This signal
indicates the number of transaction layer packets stored in the
retry buffer (saturation limit is 31).
