6.9 Enhanced Direct Memory Access Controller (EDMA3)
The EDMA3 controller handles all data transfers between memories and the device slave peripherals on
the device. These data transfers include cache servicing, non-cacheable memory accesses, user-
programmed data transfers, and host accesses.
6.9.1 EDMA3 Channel Synchronization Events
Each EDMA3 channel controller supports up to 32 channels which service peripherals and memory.
Table 6-12 lists the source of the EDMA3 synchronization events associated with each of the
programmable EDMA channels.
