PFUSE: Configuration fuses¶
Introduction¶
PFUSE contains factory-set configuration values that cannot be overridden by software later on. The name comes from the fact that once the Configuration has been set, it is possible to avoid further writes by blowing the power supply or the data lines of the the write circuitry.
