EVTSELx
EDMA event selection bits for channel x. Allows mapping of the EDMA events to the EDMA channels.
The EVTSEL0 through EVTSEL15 bits correspond to the channels 0 to 15, respectively. These
EVTSELx fields are user−selectable. By configuring the EVTSELx fields to the EDMA selector value
of the desired EDMA sync event number (see Table 23), users can map any EDMA event to the
EDMA channel.
For example, if EVTSEL15 is programmed to 00 0001b (the EDMA selector code for TINT0), then
channel 15 is triggered by Timer0 TINT0 events.
