Figure 65. LVD Startup Behaviour
Note: When the LVD is enabled, the MCU reaches its authorized operating voltage from a reset state.
However, in some devices, the reset signal may be undefined until V
quence, the I/Os may toggle when V
Because Flash write access is impossible below this voltage, the Flash memory contents will not be cor-
rupted.
