Shutdown Controller

The Shutdown Controller controls the power supplies VDDIO and VDDCORE and the wake-up
detection on debounced input lines.
The Shut Down Controller is supplied on VDDBU and allows a software-controllable shut down
of the system through the pin SHDN. An input change of the WKUP pin or an alarm releases the
SHDN pin, and thus wakes up the system power supply.
