EDMA channel synchronization events [C6711/11B only]
The C67x EDMA on the C6711/C6711B device 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 22 lists the source of synchronization events associated with each of the programmable EDMA
channels. For the C6711/11B, 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).
