EDMA channel synchronization events
The C62x EDMA supports up to 16 EDMA channels. Four of the sixteen channels (channels 8−11) are reserved
for EDMA chaining, leaving 12 EDMA channels available to service peripheral devices. Table 15 lists the source
of synchronization events associated with each of the programmable EDMA channels. For the C6211/11B, the
association of an event to a channel is fixed; each of the EDMA channels has one specific event associated
with it. For more detailed information on the EDMA module, associated channels, and event-transfer chaining,
see the TMS320C6000 DSP Enhanced Direct Memory Access (EDMA) Controller Reference Guide (literature
number SPRU234).
