AD5643R-5 cannot output voltage

I tied /LADC pin to GND, and /CLR pin to VDD on hardware connection.

I used an FPGA  to sent config signals to AD5643.

First I sent 00_111_000_0000_0000_0000_0001 to use the internal reference, I can see a 2.5V output on the  REFOUT pin.

Then I sent 00_011_111_1111_1111_1111_1111 to config DAC output ,but I can't see output on the VOUTA and VOUTB pins, they are still 0V.

How should I do to get the right output? Should config more registers?
