    Providing negative value to an analog pin in PSoC


       Hi all,


      At the moment I am trying to provide a negative value to a comparator positive input pin, so the comparator output will be triggered high once a negative voltage goes lower than this defined threshold.


      Unfortunatelly it looks like the PSoC does not accept a negative signal. I have checked this with scope and anything that goes below 0 Volts just disappears from the input signal.


      Am I doing somethign wrong or this is, in fact, the way it is?
