46.6.5 VDDANA Scaler

The VDDANA scaler generates a reference voltage that is a fraction of the device’s supply voltage, with 64 levels. One independent voltage channel is dedicated for each comparator. The scaler of a comparator is enabled when the Negative Input Mux bit field or the Positive Input Mux in the respective Comparator Control register (COMPCTRLx) is set to VSCALE as an input and the comparator is enabled. The voltage of each channel is selected by the Value bit field in the SCALERx registers (SCALERx.VALUE).
