Revision 1: Siemens MSS54
Definition sources
The saildot4k project publishes MSS54 and MSS54HP XDFs and explains its item-description confidence indicators. Some English labels are best-effort interpretations.
Choose the hardware branch
Use the MSS54HP child page for HP-specific material. MSS54 and MSS54HP definition matching describes what to retain when selecting a definition.
Sources
Curated reference notes. Applicability follows the cited sources; hardware testing by this wiki is not implied.
Revision 2: Siemens MSS54
Family and variant scope
The saildot4k collection separates MSS54 and MSS54HP definitions. Its English labels are interpretations, and item descriptions preserve search/match information. MSS54/MSS54HP project guide. Choose MSS54HP for the larger-image hardware branch and its CSL context.

This is an example from the pinned collection, not a support statement for every MSS54 release. MSS54 hw2801 Complete XDF.
The repository has Basic and Complete collections. Those names describe the supplied definition sets; they do not establish that every address or interpretation has been independently verified. Retain the complete software identity and confidence comments when using the matching file.
Read next
Keep an example from another release under this ECU branch with its own source definition and software ID. Use the HP child branch for HP-specific offsets and hardware observations.
