AD9914 , BPSK realization

I have question about realization BPSK in AD9914.

This device support mode F=0111, which can form 8 bits phase shift

every cycle (for example, 180 and 0 degrees). But frequency

perform by 24 bits, although I need perform frequency with

32 bit resolution. I found "parallel port streaming enable" bit,

which can allow perform phase and frequency separately in different

cycles and for next cycle assert of the IO_UPDATE pin,

but I need update phase permanently (every cycle) for BPSK.

Do you have other good decision for BPSK?

Can you please help me?
