Trace Instrumentation generates an instrumentation trace packet that contains the value of the provided register.

This is an alias of SYS. This means:

The encodings in this description are named to match the encodings of SYS.
The description of SYS gives the operational pseudocode, any constrained unpredictable behavior, and any operational information for this instruction.
