TDA4VM: Understanding NAVSS Interrupt Configuration

Part Number: TDA4VM

Hi TI,

the TDA4VM TRM (SPRUIL1B – MAY 2019 – REVISED DECEMBER 2020) mentions an application example for configurring NAVSS Interrupt support in chapter 10.2.1.4. This example helped me a lot in understanding the basic ideas, but I still have some questions:

Q1: Table Table 10-108 says, that for the Ring Accelerator Module, I have to write 10 into Register RING[316]_EVT. Where do I define R#=316? I know, that 316 = 300 (UDMAP0 Receive, from table 10-533) + 16 (ring which is used). But Sciclient_rmIRqSet has no parameters to set this variable.

Q2: If I want to trigger the interrupt, which is mentioned in the example, manually (by writing to a specific register), what is the correct register to write to? Do I have to use the corresponding RINGACC_EVENT_j register (316) where I have to write the global event (10)?

Thanks for your help and best regards,

Felix
