Hi There,

 

I want to check how to use the USB controller of LS1046A.

There is a difference between the contents of the reference board and the application note.

Please tell me the correct unused processing the following conditions.

 

[Conditions]

 ・USB1 works with USB2.0.

 ・USB2 / 3 is unused.

 

【Check】

1.Does USB [2/3] _VBUS need a 5V power supply?

2.Is the USB [2/3] _ID 1kΩ connection correct?

3.Does USB [1] _RESREF require 200Ω?

4.Does USB [2/3] _RESREF require 200Ω?

 

Best regards
