Does PTN5110 support Alt mode negotiation?

[Danz1]

Hi,

I am using PTN5110NHQZ as the TCP controller in my application. I would like to know the steps to perform ALT mode negotiation (eg write to which register; Power-role and Data-role setting). Any document to recommend?

In my application, the device get power from external display monitor.

Thanks.

Hello,

I hope all is great with you.

Unfortunately, we do not have any documentation about the DP ALT mode.

In this case, you can download the PD stack with Alt mode support from NXP to study the code. The spec can be download from the USB IF website. I think you have to be a registered member to download it.

I hope this information helps.

Regards,
