53.1 Description

The TrustZone Advanced Encryption Standard Bridge Address Space Controller (TZAESBASC) is used to define which part of the product memory space is accessed through the TrustZone AES Bridge.

The user can define up to 8 regions. Each region can be sized independently with a granularity of 4 Kbytes, and is defined by a base address and a top address.

The address bus of each peripheral host which can access the TrustZone AES Bridge goes through a TZAESBASC Address Manager. If a transfer address matches an enabled region, the address is modified in order to route the transferred data through the TrustZone AES Bridge, otherwise the transferred data is routed directly to/from the addressed peripheral client.
