I'm confused about the eDMA operation on the MCF54415. The user manual makes repeated statements referring to the 64 channel DMA controller but only 16 seem to be implemented. Also, there is no facility to multiplex the 64 possible DMA sources to the 16 implemented controllers. What am I missing?
Also, I'm trying to use DSPI with DMA and haven't been able to find any sample code for eDMA or DSPI. Is anyone aware of any eDMA and/or DSPI sample code for the MCF54415?
