    Separate analog and digital power supply for PSoC-4M




      I was wondering whether is it possible to connect (VSSA and VDDA) to a different supply voltage other than that is being used for (VSSD and VDDD).


      Also is it possible to connect VSSA to a slightly negative voltage, say -200mV as compared to VSSD which is referenced 0V for digital peripherals.


      The configuration would look like:


      VDDD = 3.3V


      VSSD = 0V


      VSSA = -0.2V


      VDDA = 3.1V  (VDDA-VSSA = 3.3V)
