TPS65988: “Initiate Swap to UFP” and “Process Swap to UFP” in Firmware Tool of TPS65988DH

I read descriptions of “TPS65987DDH Host Interface Technical Reference Manual (Rev. B)”.

I cannot understand different between “Initiate Swap to UFP” and “Process Swap to UFP”.

Could you tell me different between “Initiate Swap to UFP” and “Process Swap to UFP” ?

    Hi,

    'Initiate Swap to UFP' will send a DR_Swap message to the port partner if the current data role is DFP. If this is not set, there is no DR_Swap sent automatically.

    'Process Swap to UFP' will process a DR_Swap message coming from the port partner if the current data role is DFP. If this is not set, the PD will send a 'Not_Supported' message to the port if it receives a 'DR_Swap' when the present role is DFP.
