Programming the SKY fuse locks the Secret Seeds and Session Encryption Key registers so that the contents cannot

be read or changed. Once locked, these registers cannot be unlocked. The SKY fuse also disables the Secure

Personalization mode and disables the Write System Zone with Integrated MAC command.

The Configuration Memory Access requirements for all four of the Security Fuse states is described in Appendix G.

Note that it is not necessary to initialize the Session Encryption Key registers since any data contained in these

registers will be overwritten by the first Authentication Activation attempt.
