i.MX6SL HSIC connection when unused.

[satoshishimoda]

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

Hi Satoshi

you are right: when HSIC is unused, no problem leave these pads floating

and they can be used for GPIO.

Best regards

igor
