Regrding channel bitmap and ping pong buffers in tsip interface

Hello Madhuri,

Channel bitmap is described well in section 2.4. I would suggest you read it again.

Ping-pong buffer concept is fairly common. When TSIP peripheral is getting data in Ping buffer and your software can handle the data in Pong buffer and then the other way around so it is continuous.

The best way to under it is to run example software on platform and use CCS to view memory (registers and buffers & data).

For TCI6486, I think we only offer CSL:

However, you can look at a sister chip, C6678 which also offers TSIP to see how TSIP is implemented

There is TSIP example available in this software package.

Are you just starting TCI6486 project or your project is already using TCI6486 and you just want to understand more about it?

best regards,

David Zhou
