5.1 Detailed Description

To enable the security features of CryptoMemory®, personalize the device by setting up registers and loading appropriate passwords and keys. This is accomplished through programming the Configuration zone of CryptoMemory using simple write and read commands. To gain access to the Configuration zone, the secure code (Write 7 password) must be successfully presented. After writing and verifying data in the Configuration zone, the security fuses must be blown to lock this information in the device. For additional information on personalizing CryptoMemory, please see the initialization examples in 9 Synchronous Initialization Example and 11 Asynchronous Initialization Example.
