Caution:

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.

When the LVD is not activated with the associated option byte, the WDGRF flag cannot be

used in the application.
