Application notes
The LVDRF flag is not cleared when another reset type occurs (external or watchdog); the
LVDRF flag remains set to keep trace of the original failure. In this case, a watchdog reset
can be detected by software while an external reset cannot.
When the LVD is not activated with the associated option byte, the WDGRF flag can not be
used in the application.
