Voltage monitor electrical characteristics
The device implements a Power On Reset module to ensure correct power-up initialization, as well as three low voltage
detectors to monitor the VDD and the VDD_LV voltage while device is supplied:
POR monitors VDD during the power-up phase to ensure device is maintained in a safe reset state
LVDHV3 monitors VDD to ensure device reset below minimum functional supply
LVDHV5 monitors VDD when application uses device in the 5.0V ± 10% range
LVDLVCOR monitors low voltage digital power domain
