EDMA module and EDMA selector<br />
The C67x EDMA supports up to 16 EDMA channels. Four of the sixteen channels (channels 8−11) are reserved<br />
for EDMA chaining, leaving 12 EDMA channels available to service peripheral devices.<br />
The EDMA selector registers that control the EDMA channels servicing peripheral devices are located at<br />
addresses 0x01A0FF00 (ESEL0), 0x01A0FF04 (ESEL1), and 0x01A0FF0C (ESEL3). These EDMA selector<br />
registers control the mapping of the EDMA events to the EDMA channels. Each EDMA event has an assigned<br />
EDMA selector code (see Table 30). By loading each EVTSELx register field with an EDMA selector code, users<br />
can map any desired EDMA event to any specified EDMA channel. Table 29 lists the default EDMA selector<br />
value for each EDMA channel.<br />
See Table 31 and Table 32 for the EDMA Event Selector registers and their associated bit descriptions.<br />
