THE DAC SERIAL DATA STREAM IS COMPOSED OF TWO CONCATENATED 16 BIT WORDS.<br />
THE FIRST HALF GOES TO DAC B (Vernier). THE SECOND HALF INTO DAC A (Main RF)<br />
THE PAIR OF WORDS SHOULD BE SENT AS ONE 32-BIT WORD.<br />
IF ONLY DAC A IS TO BE LOADED, THAN 16 BITS ARE TRANSMITTED FOLLOWED IMMEDIATELY BY<br />
DEASSERTING THE ~DAC_SYNC.<br />
BOTH DAC OUTPUT REGISTERS ARE LOADED WHEN ~DAC SYNC IS ASSERTED.<br />
