The invention concerns an electronic watch () including:

Watch fitted with an electric motor control case

An electronic device including an electronic circuit () for delivering an output signal (CKS) and a programmable non volatile memory () coupled to the electronic circuit to allow storage of a binary word (EED[]) representative of at least one adjustable feature (C, C) of the electronic circuit (), this electronic device including at least first and second supply terminals (PAD_VDD, PAD_VSS), to which first and second supply voltages are applied (V, V) and at least one output terminal (PAD_OUT) at which the output signal from the electronic circuit is delivered. Circuits are provided for switching the output terminal into a so-called high impedance state so as to allow the introduction, in serial form, via this output terminal, of data bits intended, in particular, to be stored in the non volatile memory of the device. This device is applied, in particular, for adjusting the features of an oscillator circuit.
