I would like to consult on a problem I have with my AD5724 DAC.

I wanted to operate it as BiPolar at all its four ports.

What I managed to have is ports A-C works fine and port D insists on translating the Data word I sent it as if it

was initialized to be UniPolar. It translation works "fine" and it changes its output level  but not according to the required polarity.

I started with one BiPolar word (+/- 5V <-- 0x3)  to all at once (DAC Adress = 0x100) but changed it to four separate approach for each

register, but the same problem remained. I added NOP cycles, no help ...

Please suggest what else to check
