3. Configuration Memory

The configuration memory consists of 2048 bits of EEPROM memory used for storing system data, passwords, keys,

codes, and access control registers for each user zone. Access rights to the configuration memory are defined in the

control logic and cannot be altered by the user. These access rights include the ability to program certain portions of

the configuration memory and then lock the data written through use of the security fuses. The Read System Zone and

Write System Zone commands are used to access the configuration memory. For Configuration Memory Maps see

Appendix D.
