7.8.4 EDMA3 Channel Synchronization Events

The EDMA3 supports up to 16 DMA channels for CC0, 64 each for CC1 and CC2 that can be used to service system
peripherals and to move data between system memories. DMA channels can be triggered by synchronization events
generated by system peripherals. The following tables lists the source of the synchronization event associated with
each of the EDMA CC DMA channels. On the C6670, the association of each synchronization event and DMA
channel is fixed and cannot be reprogrammed.
For more detailed information on the EDMA3 module and how EDMA3 events are enabled, captured, processed,
prioritized, linked, chained, and cleared, etc., see the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone
