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.
