AD9164 EVAL Board Control through SPI

Hello, this should be posted to the high-speed DAC community.  I would move it for you but it seems I don't have the permission to do so on this forum.

HI deljones I moved to the question to High-Speed DACs. @mentioning  Biao.H may be able to help.

yes. the user can use P2 to control AD9164. but might need to disconnect these wires from on board PIC processors. recommend to start from lower SPI speed, like few hundreds kHz. 

also hook up the GND to the user's SPI communication cards. 

I analyzed the signal that the ACE program sends to the AD9164-EVAL Board through Logic Analizer, and I am making the same signal through the P2 connector.
When you want to change the value of the 0x0040 address to 0x01
After sending the values 0x00, 0x40, 0x01,
0x01, 0x13, 0x00 n
Send 0x01, 0x13, 0x01
But the register value doesn't change.
What is the problem?
