USB BC 1.2 (CDP, SDP) can support both USB 2.0 and USB 3.0 communication.
DCP mode does not enumerate a device. That is, there is no USB communication.
AN92554 - Implementing Battery Charging Features using HX3 is very helpful to understand USB BC 1.2.
Thank you for your reply.
I have one question to make sure.
CYUSB3314 supports DCP mode itself.
In this time, CYUSB3314 has only charging function without USB2.0/3.0 communication.
Is my understanding correct?
I apologize for bothering you…
Yes. If CYUSB3314 works on DCP mode, there is no support USB 2.0/3.0 communication.
It is USB BC specification. You can refer to on page 3, AN92554.
