Protocol Errors
#1 Code Violation: Wrong 10b symbol detected.
#2 Disparity Error: Wrong disparity detected.
#3 ALIGN Error: ALIGN primitive frequency is outside the specification requirements.
#4 STP Signaling Latency Error: DWORD difference between HOLD and HOLDA is greater
than entered value in the HOLD/HOLDA Response Timeout field.
#5 STP Invalid State Transition (Unexpected Primitive): Second SATA_SOF is encountered
before SATA_EOF, and other unexpected primitives.
#6 STP Invalid State Transition (Primitive Timeout): Timeout between two paired
primitives is above entered value. 65000 DWORDs is default. For example, it can occur
between WTRM and R_OK, or X_RDY and R_RDY. It expects device (or host) to send a
response, but response is not received after 65000 DWORDs. You set Primitive Response
Timeout and HOLD/HOLDA Response Timeout in the Settings tab Analyzer Settings
section.
