2. User Memory
The User EEPROM Memory characteristics are summarized in Table 2-1 below. User Memory
is divided into equally sized User Zones. Access to the User Zones is allowed only after security
requirements have been met. These security requirements are defined by the user in the config-
uration memory during personalization of the device. The default configuration is open
read/write access to all user memory zones.

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.
