GPIO (Vddio) operating at voltage higher than Vddd and Vdda in PSoC3/5

Version 1
    Question: Can Vdda and Vddd be at lesser voltage as compared to Vddio? For example Vddio is connected to 5 V and Vdda and Vddd is connected to 3.3V.

     

    Answer:

    No, Vdda should be the highest voltage in the system to guarantee the operation.
