About pin E10 and F10 of i.MX6D

[宗標廖]

Hello, community

I do not use USB Host function,so USB_H1_DP(E10) and USB_H1_DN(F10) will be left not be connected.

Should I just left it not connected or should I connect it to ground or connect it to 3.3V.

Thank you!

Hello,

The recommended connections for unused analog interfaces can be found in the section,
“Unused analog interfaces,” of the Hardware Development Guide for i.MX 6Quad, 6Dual, 6DualLite,
6Solo Families of Applications Processors (IMX6DQ6SDLHDG).

In particular, USB_H1_DN, USB_H1_DP, USB_H1_VBUS, USB_OTG_CHD_B,

USB_OTG_DN, USB_OTG_DP, USB_OTG_VBUS may be left float.

Have a great day,
Yuri
