Implications of disconnecting the transmit bus on AD9364 if unused

In our application we don't plan to use the AD9364 / AD9361 transmit path.


Q: Can we leave the AD9361 / AD9364 P0_Dn/TX_Dn bus, TX_FRAME and FB_CLK signals disconnected (or pulled low) ?


and what are the software implications?

Do we need to modify the driver software to prevent any issues? (we are currently using the OS option and our application only reads the receive buffer).


Does the software use the P0_Dn bidirectional bus to read any registers/configuration?
