3 Monitors VDDA, active only in full performance mode. Indicates I/O and ADC performance degradation due to low supply
voltage.
4 Monitors VDD, active only in full performance mode. MCU is monitored by the POR in RPM (see Figure A-1)
5 Digital functionality is guaranteed in the range between VDD(min) and VLVRA(min).
6 Monitors VDD. Active in all modes.
7 The API Trimming bits must be set that the minimum periode equals to 0.2 ms. fnominal = 1/0.2ms
