Hi to everybody
Please can i have your help?
I would like to control an AD5328 DAC by a dsPIC33F.The AD5328 wants a SSEN kept low during the entire transmission,but the dsPIC33F in framend mode just send a pulse at the beginning of transmission. I could drive that pin as a normal I/O ,but it looks that interrupt and flags are not able to indicate when the transmission is done. Is that correct? Any hint about it? Many thanks

You can use the dsPIC33F in normal SPI mode with the normal SS# pin operation (use SPIxCON2 register to disable frame mode), interrupts occur when the transmit buffer has emptied regardless of mode. You would not use framed mode for this, as you point out the AD5328 requires a normal slave select.

Please check the data sheet again (??!!), the SYNC# signal performs the same function a normal SSEN# signal except you have to assert SYNC#, do your transfer, and de-assert SYNC# each time you access the device.

Please check this data sheet again:
Figure 3 has no SSEN pin ??!!
