The Voltage Monitor contains a 2-channel analog multiplexor that allows an incoming analog signal to be routed directly to the analog to digital converter, or allows the signal to be routed to a prescaler circuit before being sent to the ADC.
See the Configuring Current, Voltage, and Temp peripherals for information on the Digital filtering factor, Acquisition time, and Comparison Flag Specifications.
The only control unique to this peripheral is Maximum voltage (described below).

The maximum anticipated voltage measured by this Voltage Monitor peripheral pad. The range is -12V to +12V (the voltage range is NOT bipolar). The ADC is capable of measuring a voltage range of 0 - Vref. For the Internal voltage reference, this value is 2.56V. SmartGen automatically configures the Pre-scalar in the AB Analog Block for this peripheral based on the maximum voltage such that the input voltage is scaled up / down (if the voltage given to ADC is in the proper range). SmartGen also post-scales the digital result of ADC conversion so that it returns a result in your specified range.
