TPS65987DDK: Tx Identity configuration

TPS65987DDK: 0x47 Tx Identity value

Tool/software:

Hi

What value should I set 0x47 field by Application Customization Tool?

My application is DRP with DP Altmode feature, and work as USB Device up to USB2.0.

TBT, USB4 and USB Host feature are not supported.

Is the following setting correct?

Especially I'm not sure about "Alternate Mode" in VDO0, "Max Power" in VDO1 and DFP/UFP VDO Version.

I attached my pjt for your reference. I'm glad if you review only 0x47 field.

    Hi Eugene,

    For the settings you circled

    Alternate Mode: Supports that reconfigures signal

    UFP VDO Version: 0x03

    DFP VDO Version: 0x02

    DP alt mode reconfigures the signals o nteh type-C connector

    The VDO versions are defined and fixed in the USBCPD Spec section 6.4.4.3.1.X

    Thanks and Regards,

    Chris
