I need a reference circuit for using the ADSP-BF700 series  processors

In the ADSP-BF700 series data sheet I find that the GPIO pins can be multiplexed using two bits. According to the values of those two bits each GPIO pin is connected to four different signals.

I am designing a 24 GHz radar and I have selected the ADSP-BF706 as the DSP processor and MCU to control the different chips of the radar. But I do not find those two control bits to connect them to the IC.

Can you help me?
