BQ24253: D+D- connection mode

Donghang Jiang
Prodigy 50 points
Part Number: BQ24253

If I use USB to power BQ24253 and simultaneously need USB to transfer data, do I have to ensure that USD's D+D- and BQ24253's D+D- are always connected? Under such a premise, BC1.2 detection is carried out right after power-on, and after the detection is completed, D+D- can be used normally for data transmission, right?
