Zusammenfassung:The disclosed technology is generally directed to microcontrollers. In one example of the technology, an operating system is run on at least one processor of a multi-core controller. At the operating system, a command that is associated with a manufacturer test mode is received. A permission associated with the command is requested. The permission is based, at least in part, on the status of a one-way e-fuse. Responsive to the permission associated with the command being granted, the command is caused to be processed.
