Hercules™ AJSM Unlock

This application report explains how to utilize the features of the Advanced JTAG Security Module (AJSM) contained on Hercules devices. It is the responsibility of the developer to protect the AJSM key. Failure analysis is not an option, unless the AJSM key is provided. The lock can be changed, but that information should be provided to TI, if possible.
