3.2. Modes of operation and execution

If the Security Extension is implemented, the programmers model has Secure and Non-secure views of the operating modes, operating states, and privileged access and unprivileged user access.

If the Security Extension is not implemented, the programmers model has only Non-secure views of the operating modes, operating states, and privileged access and unprivileged user access.

See the ARM®v8-M Architecture Reference Manual for information about the modes of operation and execution.
