Description
This counter increments when any of the following conditions are encountered:
•
In SAS, when a Dword interrupts either a Triple or Redundant Primitive Sequence
•
In SAS, when a Triple or Redundant Primitive Sequence is started without having the
required gap since the previous Primitive Sequence
•
In SAS, when more than 3 consecutive Identical Triple Primitives are detected as part of the
Triple Primitive Sequence, or more than 6 consecutive identical Redundant Primitives are
detected as part of a Redundant Primitive Sequence
•
In SATA, for any violation of the structure of a Continued Primitive Sequence. This is strictly
2 or more Primitives, followed by a CONT Primitive, followed by Scrambled Primitive Data or
CONT Primitives. For example: One Primitive followed by a CONT, or a missing CONT
Primitive, etc.
This counter increments when a multiplexing alignment error occurs. These errors can occur
only when the signal through the port contains two logical channels. Every other Dword on the
physical port must belong to a single logical channel.
This counter increments when any of the following errors are encountered:
•
Bad OOB or Speed Negotiation error
•
Framing Error
•
CRC Error
•
Loss of Sync
•
CV
•
Disparity Error
•
Primitive Error
