Features
Features
• 4 or 5 (product variant dependant) High-voltage inputs with VS/2 threshold voltage
• Wake capability for system stop mode and system sleep mode
• Edge sensitive wake-up feature configurable for transitions from low to high, high to low or both directions
• MON inputs can also be evaluated with ADC in Active Mode, using adjustable threshold values (see also
).
• Selectable pull-up and pull-down current sources available

Introduction
This module is dedicated to monitor external voltage levels above or below a specified threshold. Each MONx
pin can further be used to detect a wake-up event by detecting a level change by crossing the selected
threshold. This applies to any power mode. Further more each MONx pin can be sampled by the ADC as analog
input.
