BF707 Unused DMC0 Pins, Termination

I'm planning on using the BF707 (ADSP-BF707KBCZ-3) in SPI slave boot mode, so no external DDR2/3 is needed.  However, I can't find any place that specifies how to terminate all the unused DMC0 pins.  Is it okay to leave these floating?  Do the VDD_DMC balls still need to be powered?
