Other Parts Discussed in Thread: TPS65982

hello

I  use the TPS65982 as Power source provider and as a data UFP role.

I have configured 2 PDO as source , and None as Sink.

I have configured the Port Type as a ( PR & DR swap   mode 6)

But how to force the port to work  as UFP ?  ( i have tried many configuration but no success with the Control Config Register) ?

Thanks

Franck

    If you want to be power provider / data UFP, you must configure the "USB Type-C Port Presentation" as DRP Toggling.
    Also, how have you configured the "Receptacle" - USB2 or Fully Featured Type-C?
    Do you have any accessory support enabled?

    Within "Control Configurations", it is possible to configure the Initiate Swap and Process Swap transitions according to your application. If you want your system to be a provider of power only, it should be configured to only Initiate and Process swaps to Source. To be a UFP only, only Initiate and Process swaps to UFP.
