7.27.2 Comparator
The analog comparator can compare voltage levels on external pins and internal voltages.
The comparator has five inputs multiplexed separately to its positive and negative inputs.
7.27.2.1 Features
• Selectable external inputs can be used as either the positive or negative input of the
comparator.
• Voltage ladder source selectable between the supply, multiplexing between internal
VBAT_PMU and ACMPVREF.
• 32-stage voltage ladder can be used as either the positive or negative input of the
comparator.
• Supports standard and low power modes
• Interrupt capability.
