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?
