On the TMS320VC5509, the channel frame index applies to both source and destination and this register behaves as DMA_CFIn. On the
TMS320VC5509A, DMA_CSFIn and DMA_CDFIn provide separate source and destination frame indexing. The 5509A can be programmed
for software compatibility with the 5509 through the Software Compatibility Register (DMA_GSCR).
