The invention describes an electronic device and a method for operating the electronic device. The electronic device includes one or more circuit components. The electronic device further includes one or more fuses and one or more non-volatile memories to disable the access of at least one of the one or more circuit components. Each of the one or more non-volatile memories includes one or more firmware, which are used to program at least one bit to manage the access of the at least one circuit component. The method includes performing a power-up sequence in a power cycle for the electronic device. The method further includes determining a state of circuit and a state of a bit for selectively enabling a test function.
