7.8.4 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2 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 EDMA3CC DMA channels. On the C6672, 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
Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 69.
