Note: Program Trace can be implemented using either Branch History/Predicate Instruction
Messages, or traditional Direct/Indirect Branch Messages. The user can select between the
two types of Program Trace. The advantages for each are discussed in
Branch Trace Messaging
TCODES above will not be messaged out.
