Figure 28-3. Fast Startup Circuitry
Each wake-up input pin and alarm can be enabled to generate a Fast Startup event by writing at
1 the corresponding bit in the Fast Startup Mode Register SUPC_FSMR.
The user interface does not provide any status for Fast Startup, but the user can easily recover
this information by reading the PIO Controller, and the status registers of the RTC, RTT and
USB High Speed Device Controller.
