We have configured ADCB inputs for differential sampling such that ADCIN0/ADCIN1 form one pair and ADCIN2/ADCIN3 form the second pair. ADCIN0 and ADCIN1 are at same voltage level (1.25) in the absence of any signal. So a differential reading will be close to 0 Volts. If both inputs go bad at the same time for e.g. both are shorted to Vdd or Vss then the differential pair will again read close to zero. It is therefore a requirement that for diagnostic/self test readings from both the analog inputs of the differential pair be measured and displayed. This needs to be done during initial system power up. For normal operation only differential readings are required. Please guide if there is some method for reading both analog inputs of a differential pair. One solution that comes to my mind is to configure additional SOCs for sampling individual analog inputs and enabling trigger source. Once the readings are done then these SOCs can be disabled by disabling the trigger source. Let me know if there is a better and more efficient way.
