AD9910 Eval Board under external MCU control. Cut traces?

Hi,

 

In the message:

https://ez.analog.com/message/153592#153592

 

there is some discussion of the need to cut traces on the AD9910 eval board in order to use IO_UPDATE.

 

Is this true? Didn't the FPGA programmer make his IO lines tri-state when the "disable" jumpers are set?

 

Do I have to cut all the traces going from the FPGA to the AD9910?

 

David
