Shutdown Controller
RTTWKEN
The Shutdown Controller controls the power supplies VDDIO and VDDCORE and the wake-up
detection on debounced input lines.
The Shutdown Controller is continuously clocked by Slow Clock. The Power Management Con-
troller has no effect on the behavior of the Shutdown Controller.
