Primitive Sequence Errors
(PSE)
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.
Multiplexing Alignment
Errors (MAE) 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.
Any Errors (AE)
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
