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.
The Shutdown Controller manages the main power supply. To do so, it is supplied with VDDBU
and manages wake-up input pins and one output pin, SHDN.
