1. Voltage Regulator Disabled. High Impedance Output
2. Monitors VDDA, active only in Full Performance Mode. Indicates I/O & ADC performance degradation due to low supply
3. Monitors VDDX, active only in Full Performance Mode. MCU is monitored by the POR in RPM (see
4. The API Trimming bits must be set that the minimum period equals to 0.2 ms.
5. A hysteresis is guaranteed by design

Bandgap Reference Voltage
The LVR monitors the voltages VDDF and VDDX. If the voltage drops on
these supplies to a level which could prohibit the correct function of the
microcontroller, the LVR triggers.
