23.6.5.5 Continuous Mode
Continuous mode is the default mode for BOD33.
The BOD33 is continuously monitoring the supply voltage (VDD or VBAT, depending on BOD33.VMON) if it is enabled (BOD33.ENABLE=1) and if the BOD33 Configuration bit in the BOD33 register is cleared (BOD33.ACTCFG=0 for active mode, BOD33.STDBYCFG=0 for standby mode).
