ADC VINPx, VINMy, x=0-11, y=0, 2, 4, x =0,1,…,11AnalogVINPx/VINMy Analog inputs for ADC Module 0
Note:
  1. Channel 12 is attached internally to the Temperature Sensor Monitor.
  2. Channel 13 is attached internally to the IVREF, Band Gap 1.2 Volt Monitor.
Note: Please consult the section Signal Description and ADC Pinout I/O Description table to determine which pins provide which input signals, depending on the device package in use.

All the VINPx signals listed above can be used for single-ended input. Only 3 specific VINPx inputs can be combined with the VINMx inputs for differential measurements.

  • (ADC_VINP0 (Diff +) , ADC_VINM0 (Diff -) )
  • (ADC_VINP2 (Diff +) , ADC_VINM2 (Diff -) )
  • (ADC_VINP4 (Diff +) , ADC_VINM4 (Diff -) )

These pairs are configured in the CHNCFG3n (n=1,2,3) register by setting the DIFF bits corresponding to the signal pairs in use.
