AWR2944: Question about DSP TPCC A/B/C and HWA_DMA_REQ EVENT

Hi,

In C:\ti\mcu_plus_sdk_awr294x_08_02_00_25\source\drivers\hw_include\awr294x\cslr_soc_defines.h we found for DSP TPCC A/B/C, the last 32 events are same for these 3 TPCC which are all events of HWA DMA REQ, 

My understanding is that only total 32 HWA DMA REQ events can be used in AWR2944. Then why there are 3 TPCCs to support same 32 HWA DMA REQ events?

Pls correct me if I miss anything.

Thanks,

Chris
