Will there be any HW dependencies when a OC situation occurs:</P><P>1: Activating the OC input, will the USB data transfer be interrupted?</P><P>2: Will the OC input by any means directly control the PWR output?</P><P>I am thinking of any HW links between functions of the USB block.</P><P>A lot of reference designs are using any other GPIO pin for OC status, which I assume requires the USB driver to be adapted to that. But as the Reference Manual lists a number of dedicated pins for OC status, I'm wondering if the chip itself has any HW functionality for handling OC situations.</P></BODY></HTML> Tue, 15 Nov 2016 09:19:52 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6UL-USB-over-current-functionality/m-p/661851#M101611 hansjpetersen 2016-11-15T09:19:52Z Re: iMX6UL USB over current functionality https://community.nxp.com/t5/i-MX-Processors/iMX6UL-USB-over-current-functionality/m-p/661852#M101612 <HTML><HEAD></HEAD><BODY><P>See&nbsp;<A href="https://community.nxp.com/thread/438911">https://community.nxp.com/thread/438911</A>&nbsp;</P></BODY></HTML> Tue, 15 Nov 2016 11:52:59 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6UL-USB-over-current-functionality/m-p/661852#M101612 RossMcLuckie 2016-11-15T11:52:59Z
