Understanding the Unformated Trace & Diagnostic Data Packet Encapsulation for RI...
summary
Specification standardizes an encapsulation that already ratifies E‑Trace use and general unformatted diagnostics, and it ships a one‑byte header with a 5‑bit length, flow and extend bits, a source ID sized 0–16 bytes, an optional timestamp up to 8 bytes, and a payload of 1–31 bytes. It defines null and null‑alignment bytes for sync, shows ATB sideband versus in‑band messaging usage, and proves practical by fitting AMBA ATB and Siemens messaging transports.
