6. A method for transferring a control signal between at least a first digital domain and a second digital domain of a system-on-a-chip, comprising:
generating, in the first digital domain, a control signal for transmission to the second digital domain comprising a pulse intended to have a nominal duration that is adapted for a level-shifting circuit that converts a signal between the first digital domain and the second digital domain; and
at an input of the level-shifting circuit, lengthening a duration of the pulse of the control signal to the nominal duration when the duration of the pulse of the control signal is shorter than the nominal duration and non-zero.
