DMA transfer with MCF52233

Hi everyone
 
I am making a project  with the MCF52233, because of  a speed constraint I need to use DMA transfer.
I Have a FIFO memory and a MCF52233; so I am qoing to send data from FIFO to mcf52233.
I am a little confused about how DMA works with external devices
In order to get the right data at right time in the MCF52233 GPIO port I need to send a clock signal to the FIFO memory.
 
How can I produce that clock signal ? using DTOUTn pin?
How can I sure that the DMA clock is synchonized with the external FIFO memory.
 
 
 
Thanks for Your helphappy smiley
 
Antonio
