USB0_DP and USB0_DM when USB not used - K60

igw — Fri, 04 Jul 2014 05:02:15 GMT

On a K60F what should we do with the USB0_DP and USB0_DM pins when we aren't using the USB peripheral?

There doesn't seem to be any guidance in the datasheet or user manual.

I was thinking that we would pull them down to GND lightly. Or should we pull them up lightly?

Thanks,

Ian

just put both of them to GND is OK.

Hi Ian,

Thank you very much for your focus on Freescale Kinetis product. I'm glad to provide service for you.

It's ok to pull the USB0_DP and USB0_DM pins down to GND.

Have a great day,
