AD9364 Tx Power Control (TPC) by CTRL_IN pins

I'd like to control AD9364 TX attenuation by CTRL_IN pins. But I can't find any information how to do this.

 

There is function ad9361_set_rx_gain_control_mode() in API, but there isn't such function for TX side

There is register 0x081 /* TX Symbol Atten Config */ in API, but there isn't this register in UG672. 

 

But the datasheet says: " In transmit mode, the BBP can use two of the pins to change the transmit gain in real time."

 

How can I configure thr AD9364 to control the TX attenuation by Control Inputs (CTRL_IN3 to CTRL_IN0)?
