RESET (Cont’d)
5.3.4 Watchdog Reset
The MCU provides a Watchdog timer function in
order to be able to recover from software hang-
ups. If the Watchdog register is not refreshed be-
fore an end-of-count condition is reached, a
Watchdog reset is generated.
After a Watchdog reset, the MCU restarts in the
same way as if a Reset was generated by the RE-
SET pin.
Note: When a watchdog reset occurs, the RESET
pin is tied low for very short time period, to flag the
reset phase. This time is not long enough to reset
external circuits.
For more details refer to the Watchdog Timer
chapter.
5.3.5 LVD Reset
Two different RESET sequences caused by the in-
ternal LVD circuitry can be distinguished:
During an LVD reset, the RESET pin is pulled low
when V

For more details, refer to the LVD chapter.
Caution: Do not externally connect directly the
RESET pin to V
component in case of internal RESET (Watchdog
or LVD).
