6.9
EDMA
The EDMA 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 EDMA channel controller supports up to 32 channels which service peripherals and memory.
Table 6-9lists the source of the EDMA synchronization events associated with each of the programmable
EDMA channels.
