TZC-400 Memory Regions Question

Hi experts,

Based on the manual of TZC-400, we could set up at most 8 regions with different security settings.

However, I'm wondering, when a normal world(non-secure) application read or write a specific address, how does the TZC-400 decide whether the address is secure or not?

I think region 1-8 could overlap addresses with each other so I'm confused about how to decide the security of an address.

Any suggestion or discussion is welcomed.

Thank you.

Simon
