Access to the user zones occurs only through the control logic built into the device. This

logic is configurable through access registers, key registers and keys programmed into

the configuration zone during device personalization. Also implemented in the control

logic is a cryptographic engine for performing the various higher-level security functions

of the device.

The configuration zone consists of 2048 bits of EEPROM memory used for storing pass-

words, keys and codes and defining security levels to be used for each user zone.

Access rights to the configuration zone are defined in the control logic and may not be

altered by the user.
