Abstract
Functions for simulating, burning and controlling integrated fuses of a device are provided by a dedicated circuit which, instead of differing from other circuits, is integrated by sharing part of the registers with the circuit that normally exists to scan test the integrity of the state of the device. The architecture is simplified and only requires an additional pin as compared to a common scan test circuit.
