TPS65994AE: DP connection bit in DATA_STATUS register

Hi Expert,

I use the TPS65994 in a notebook application, the PD controller act as DFP_D. The description of DPConnection bit in the 0x5F DATA_STATUS register is "Asseted when there is a DP connection", I am wondering that when will the DPConnection bit asserted exactly.

Is the bit updated when the PD controller receive the DP Config ACK message ? Or it updated when PD controller receive a DP Attention message?
