TRCIT
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.
