EDMA channel synchronization events

The C64x EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.

Table 18 lists the source of C64x EDMA synchronization events associated with each of the programmable

EDMA channels. For the C6411 device, the association of an event to a channel is fixed; each of the EDMA

channels has one specific event associated with it. These specific events are captured in the EDMA event

registers (ERL, ERH) even if the events are disabled by the EDMA event enable registers (EERL, EERH). The

priority of each event can be specified independently in the transfer parameters stored in the EDMA parameter

RAM. For more detailed information on the EDMA module and how EDMA events are enabled, captured,

processed, linked, chained, and cleared, etc., see the TMS320C6000 DSP Enhanced Direct Memory Access

(EDMA) Controller Reference Guide (literature number SPRU234).

† In addition to the events shown in this table, each of the 64 channels can also be synchronized with the transfer completion or alternate transfer

completion events. For more detailed information on EDMA event-transfer chaining, see the TMS320C6000 DSP Enhanced Direct Memory

Access (EDMA) Controller Reference Guide (literature number SPRU234).
