DEVICES
15.4.1 LVD Operation
Depending on the operating conditions, especially
the V
in some cases the LVD may not start. When this
occurs, the MCU may operate outside the guaran-
teed functional area (see datasheet Figure 76)
without being forced into reset state.
In this case, proper use of the watchdog may
make it possible to recover through a watchdog re-
set and allow normal operations to resume.
Consequently, the LVD function is not guaranteed
in the current silicon revision. For complete securi-
ty, an external reset circuit must be added.
