15.3.8 LLWU Flag 3 Register (LLWU_F3)
LLWU_F3 contains the wakeup flags indicating which internal 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.
For internal peripherals that are capable of running in LLS or VLLS mode, such as RTC
or CMP modules, the flag from the associated peripheral is accessible as the MWUFx bit.
Clearing of the flag will need to be done in the peripheral instead of writing a one to the
MWUFx bit.
Address: LLWU_F3 is 4007_C000h base + 7h offset = 4007_C007h

This register is unaffected by wakeup from low leakage modes
(exit from LLS via RESET or any exit from VLLS).

Wakeup flag for module 7 (Error Detect)
Indicates that an unexpected source of wakeup was active when LLS or VLLS was entered. An immediate
wakeup event was triggered and the source of the wakeup event is not known. Error handling routines
should treat this source as an unknown wakeup. To clear the flag write a one to MWUF7.

Wakeup flag for module 6
Indicates that an enabled internal peripheral was a source of exiting LLS or VLLS. To clear the flag follow
the internal peripheral flag clearing mechanism.
