Abstract
In an embodiment, a processing system includes a non-volatile memory, a hardware block, a protection circuit associated with the hardware block, and a password verification circuit. The non-volatile memory stores at least one reference password. The password verification circuit is configured to receive a password verification command, obtain a reference password, and test whether the passwords correspond. In case the passwords correspond, the password verification circuit generate an overwrite signal. The protection circuit is configured to receive a control command and selectively forward the control command to the associated hardware block as a function of the overwrite signal.
