B.1. Sending Translated/Untranslated Requests
The function with an ATC can send Memory Read requests that contain either translated or untranslated addresses. If the Endpoint wants to receive the associated translated address to update the ATC, it will generate a Memory Read with the "Translation Request" field set.
The Endpoint will receive the translated address in the associated Completion with the ATS field's S/N/G/P/E/U/W/R values.
