Patent ID: 11126234

Abstract:
A method is provided for initializing an electronic circuit in dependence on an externally applied voltage. The electronic circuit contains a first input circuit and further circuit elements. In a first step, a first enable signal for the operation of the input circuit and a further enable signal for the operation of the further circuit elements are deactivated if the voltage falls below a first threshold. In a second step, the first enable signal for the operation of an input circuit is activated and the further enable signal for the operation of the further circuit elements is deactivated if the voltage exceeds the first threshold. This is followed by the reception, with the first input circuit, of a chip select signal for the activation of the electronic circuit and of a code word at a terminal for the command bus. The activation of the further enable signal for the operation of the further circuit elements takes place if the received chip select signal and the received code word have predetermined values.
