         Choosing right ground pane for Vssd PSoC3 CY8C3866AXI-208

    jlkjslkjflk.kfjslkjfkf

      We decided to use mentioned device in 100TQFP package.

      We've choosed to sepearte digital and analog grounds. We do provide two different voltages in our design - analog and digital. Three of four quadrants are powered by analog voltage(Vddio=Vdda). I was wondering if we're supposed to choose for Vssd digital ground on quadrants powered by analog voltage as described anyway(Pin14/38/66/88) or may we provide analog ground here.

      Thanks in advance
