MCBSP DigLpbkExample mapping event with EDMA interrupt C6657 pdk

Other Parts Discussed in Thread: TMS320C6657

Derar all,

I am going through the example MCBSP_DigLpbkExampleProject that is stored under the following path \ti\pdk_C6657_1_1_2_6\packages\ti\drv\exampleProjects.

Particularly I  try to understand the implementation of the  the function registerEdma3Interrupts. 

Regarding the current implementation the CIC0 for the core 0 and CIC20 for the core 1 are used.

These Chip Interrupts Controllers are mapped with the event 20 regarding the table 7.33,  document tms320c6657.pdf. 

In the configuration file there is the following definition

ECM.eventGroupHwiNum[0] = 7;
ECM.eventGroupHwiNum[1] = 8;
ECM.eventGroupHwiNum[2] = 9;
ECM.eventGroupHwiNum[3] = 10;

That means that the interrupt with id 7 should be  mapped with the events from 0 -31. Is this right?

Why  is the interrupt 8 enabled in this project?

Best regards

George
