4.4 Secure EEPROM
The secure EEPROM is used to store the module serial number and configuration. In the future, the EEPROM
will be used for copy protection and licensing features. Please contact us for further information.
An example demonstrating how to read the module information from the EEPROM memory is included in
the Mercury XU5 SoC module reference design.
Warning!
The secure EEPROM is for Enclustra use only. Any attempt to write data to the secure EEPROM causes
the warranty to be rendered void.
