The GPIO pin mapping scheme in SigmaStudio is not intuitive because of the way SigmaStudio auto-numbers the GPIO inputs and outputs in the schematic view. In order to clear up confusion, here is a mapping table and example project that shows how the GPIO interface hardware on the board maps to the ADAU1781's hardware pins, register settings, and SigmaStudio schematic I/O cells.
