Value Description

An implementation specific error has been detected. It covers illegal field of Maintenance packet error, illegal destination ID, not supported transaction.

Reserved

Reserved. Received a packet/control symbol with an S-bit parity error (Not Valid for SERIAL)

Received a control symbol with a bad CRC value (serial)

Received an acknowledge control symbol with an unexpected ackID (packet-accepted or packet-retry). The Capture Registers don'thave valid information during this error detection.

Received packet-not-accepted acknowledge control symbol

Received packet with unexpected ackID value- out-of-sequence ackID

Received packet with a bad CRC value

Received packet which exceeds the maximum allowed size

Reserved

Link-response received with an ackID that is not outstanding. The Capture Registers don'thave valid information during this error detection.

An unexpected packet or control symbol was received

Reserved

Received unaligned /SC/ or /PD/ or undefined code-group (serial). The Capture Registers don't have valid information during this error detection.

An unexpected acknowledge control symbol was received

An acknowledge or link-response control symbol is not received within the specified time-out interval. The Capture Registers don'thave valid information during this error detection.
