I2S Input - MP0,4,5 are all 3.3V?

I'm a little lost here.  I'm trying to get I2S input working on an ADAU1701.  I've spent countless hours debugging things, making shorter cables, wrapping cables in a ground, all without success.  Then I realized that the MP0, MP4, and MP5 are all producing a 3.3V.  It's as though they're set as an output and I cannot for the life of my figure out why.

 

Besides the schematic, and configuring the ports in the control register section is there something else I need to do to make them input ports?

 

Thanks,

Gus
