2.2.6. Security

The DMC-400 can protect areas of memory from unwanted memory map aliasing but it does not support any type of security control.


  • To define regions of either the ACE-Lite address map or the APB address map as secure, ARM recommends that you use the TrustZone address space Controller (TZC).

  • If you define any memory region as secure, you must also define the APB interface as secure.
