ADAU1466 Serial Port 2 Configuration

I am looking for assistance with setting up Serial Input Port 2 as an I2S input using SigmaStudio 3.17.  I have created a project with a Input block with channels 32-33 selected.  This connects to a two channel volume control and then to two outputs.  The project link, compiles and downloads without problem and the volume control is working.  However, instead of Serial Port 2 accepting I2S signals as inputs, it is sending out Bclk and LRclk clock signals.  Looking at the ADAU1466 data sheet, pins 65-67 (Serial Port 2 pins) are bidirectional and must be configured.  Obviously, the project I have desinged with SigmaStudio is not properly configuring these pins.
