In the table shown in the image below, the function settings highlighted in yellow do not match the descriptions on the right-hand side.

Could you check below check list again?

Hi Wang,

My comments:

- Which mode does TI generally recommend?

[GC] TI generally recommends enhanced mode.

- Please confirm crystal meets datasheet requirements

- Please ensure Reset is idle high due to active low nature of pin

- This application is for an automotive. Do we can use the transformer-less network application? Following design showed in datasheet: Is the common-coil necessary?

[GC] Transformerless should work. I am unclear about what you mean by common-coil. Do you mean common mode choke (CMC)? If so, this is not required.

Sincerely,

Gerome
