Provided schematics is incorrect.

Consider that when a switch is closed then corresponding IFC_AD signal is directly connected to the 3.3V supply and cannot be driven by the processor.

Complete schematics review is possible only by a FAE request.

Even partial review is possible only if the schematics is provide as searchable PDF - i.e. not pictures.
