6.1.2.1.2. Master Security

All masters on the system interconnect are expected to drive the Secure bit attribute for every transaction. In addition to Secure bit, each master is assigned a Unique ID that identifies the source of a transaction. Accesses to secure slaves by non-secure masters result in a bus error.
