Not tested in production. The VDD rise time rate condition is needed to ensure a correct device power-on
and LVD reset release. When the VDD slope is outside these values, the LVD may not release properly the
reset of the MCU.
3.
Use of LVD with capacitive power supply: With this type of power supply, if power cuts occur in the
application, it is recommended to pull VDD down to 0V to ensure optimum restart conditions. Refer to circuit
