When the ECRC generation option is on, the TX path generates ECRC. If you turn on ECRC forwarding, the ECRC value is forwarded with the TLP. The following table summarizes the TX ECRC generation and forwarding. All unspecified cases are unsupported and the behavior of the Hard IP is unknown.In this table, if TD is 1, the TLP includes an ECRC. TD is the TL digest bit of the TL packet.
