2.6 Secure Monitor

When no bootable program is found in any external Non-Volatile Memory (NVM) during the boot sequence and Secure Boot mode is enabled, the ROM code executes the Secure Monitor.

With the set of commands implemented in the Secure Monitor, the user can send commands to write the customer key and the RSA root certificate public key hash, and execute secure applets.

For more details about the Secure Monitor and its commands, refer to the SAM9X60 data sheet (see References).
