15.3.6 LLWU Flag 1 Register (LLWU_F1)
LLWU_F1 contains the wakeup flags indicating which wakeup source caused the MCU
to exit LLS or VLLS mode. For LLS, this will be the source causing the CPU interrupt
flow. For VLLS, this will be the source causing the MCU reset flow.
The external wakeup flags are read only and clearing a flag is accomplished by a write of
a one to the corresponding WUFx bit. The wakeup flag (WUFx) if set will remain set if
the associated WUPEx bit is cleared.
NOTE
This register is unaffected by wakeup from low leakage modes
(exit from LLS via RESET or any exit from VLLS).
