48/243 Doc ID 13829 Rev 1
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, software can detect a watchdog reset but cannot detect an external reset.
Caution: When the LVD is not activated with the associated option byte, the WDGRF flag cannot be
used in the application.
