38.4.5 Supply Monitor

To activate the supply monitor, the bit SMEN in the Analog Control Register (ADC_ACR) must be written to 1.

The detection voltage can be adjusted by configuring ADC_ACR.SMVT. Refer to the section “Electrical Characteristics” for further details.

When the supply monitor detects an under voltage, an interrupt can be triggered if the bit SMEV in the Interrupt Enable register (ADC_IER) is written to 1.
