Note: The set level of the Sub-regulator voltage is only be effective in case of Main Regulator is switched
off. Otherwise (with main regulator on) the default level is applied internally by hardware to the Sub-Reg-
ulator (the register setting is not changed in this case and will be applied next time the main regulator is
switched off).
