Hi, This may take some time to get an answer on this. As you've noted, the MUXn bits can be used to connect the inputs a variety of functions including the test signal, supply measurement, temperature sensor, and the shorted inputs. However, I don't know offhand if the Input Out-of-Range Detection is on the input side of the multiplexer or on the output side of the multiplexer. If it is on the input side, the comparators would be used to measure the pins, and not the ADC connection at the time. Again, I'll need to check the design of this section and see if I can get you an answer. Joseph Wu
