GPIO Input to ADAU1701

I need to accept a TTL High / Low logic level on GPIO_2 on ADAU1701EVAL Board, and select either of two ADC inputs based on the received logic level. Is there a block in ADAU1701 toolbox that can do this?


Index  Selectable Multiplexer block has a control input that can select either of two inputs connected to the block. However, this control input can be from Index Lookup  Table, RMS Table or DC Input only. It is unable to take a GPIO_2 as input.
