Acknowledgement: The tracing mechanism is based on the tracing
mechanism developed at Infineon (formerly Siemens HL). Though this
code is somewhat different, the basics are identical to what was
originally contributed by Infineon. The contribution of Infineon
in the development of this tracing technology is hereby
