TMS320F280049: Is there a bug in F280049 X-Bar TRM?

Part Number: TMS320F280049


Hi team,

I noticed in theTRM for ePWM X-BAR mux, the available mux is 1-4.

However, in the register description, the available mux is 0-3.

And in the our example code, the mux is also 0-3

Is it a bug a in TRM? Since it was not revised in the latest 2019 TRm yet, I am wondering if I am misunderstanding this issue.

Regards,

Brian
