help
|

This option indicates that we are building a Zephyr image that
|
||||
is intended to execute in Secure state. The option is only
|
||||
applicable to ARMv8-M MCUs that implement the Security Extension.
|
||||
|
||||
This option enables Zephyr to include code that executes in
|
||||
Secure state, as well as to exclude code that is designed to
|
||||
execute only in Non-secure state. The option is only applicable
|
||||
to ARMv8-M MCUs that implement the Security Extension.
|
||||
execute only in Non-secure state.
|
||||
|
||||
Code executing in Secure state has access to both the Secure
|
||||
and Non-Secure resources of the Cortex-M MCU.
