Hi community,

 

I have a question about i.MX6SL USB HSIC.

I want to know how connect the USB HSIC pads of i.MX6SL (HSIC_DAT an HSIC_STROBE) when USB HSIC is unused.

My understanding is as below, is this correct?

 

In boot sequence:

The out of reset condition of HSIC_xxx pads are input, but there is 100k ohm internal pull-down.

So it is no problem even if these pads are floating.

 

After boot:

HSIC_xxx pads can be used for GPIO, so it is no problem even if these pads are floating by set the pads to GPIO output pins.

 

 

Best Regards,

Satoshi Shimoda
