9. Control Logic
Access to the user zones occur only through the control logic built into the device. This logic is
configurable through access registers, key registers and keys programmed into the configuration
memory during device personalization. Also implemented in the control logic is a cryptographic
engine for performing the various higher-level security functions of the device.
10. Configuration Memory
The configuration memory consists of 2048 bits of EEPROM memory used for storage of pass-
words, keys, codes, and also used for definition of security access rights for the user zones.
Access rights to the configuration memory are defined in the control logic and are not alterable
by the user after completion of personalization.
