Since the PIO state is preserved when in backup mode, any free PIO line can be used to switch
off the external regulator by driving the PIO line at low level (PIO is input, pull-up enabled after
backup reset). External wake-up of the system can be from a push button or any signal. See
Section 5.6 “Wake-up Sources”
