A processing system includes a processing unit and a hardware block configured to change operation as a function of life cycle data. A one-time programmable memory includes original life cycle data. A hardware configuration module is configured to read the original life cycle data from the one-time programmable memory and provide the original life cycle data to the hardware block. The hardware configuration module includes a register providing the life cycle data used to change operation of the hardware block. The hardware configuration module is configured to store the original life cycle data in the register and receive a command from the processing unit. The command includes a write request for storing new life cycle data in the register.
