Programming AD1836

Hello,
We have a buffer of 1152*2 bytes,which will be filled often and
which needs to be written to the DAC. We have configured the DAC for
the sampling freq. of 48KHz. The DAC is in master mode. The transfers
to the DAC are through SPORT. The document says that SPORT has an 8
word FIFO and interrupts the source of data until the FIFO is full.
We have configured the DMA to interrupt after the completion of
transfer of 1152 words.
But we are not sure about how the data is moved in
between the SPORT and DMA as we have no control whatsoever.
Can anyone kindly explain HOw the data transfer from memory to SPORT
through DMA happens. Please correct us if we have gone wrong somewhere.

Thank you
