For nRF52, nRF53, nRF54L, and nRF91 Series, the protection mechanism can use the following levels:
| Level | Description |
|---|---|
| All | Enables AP-Protect for the specified core, which disables all debug access. |
| SecureRegions | Enables Secure AP-Protect on the specified core. This disables secure debug access, but non-secure debug access is still possible. This option is only supported on device cores with ARM TrustZone support (the application core from devices of the nRF53, nRF54L, and nRF91 Series). |
