8 * The CoreSight STM supports guaranteed and invariant timing
9 * transactions. Guaranteed transactions are guaranteed to be
10 * traced, this might involve stalling the bus or system to
11 * ensure the transaction is accepted by the STM. While invariant
12 * timing transactions are not guaranteed to be traced, they
13 * will take an invariant amount of time regardless of the
14 * state of the STM.
