Hi,
I can’t find anywhere in the supplied literature a description of what the DISC signal (PC11) is used for. Is there a specification for this signal?
Best Regards

Looking at the schematic DISC is connected to the USB hardware in the lower left corner of the first schematic page. I’m not familiar with the USB protocol, but it looks like when you pull DISC High, USBDP is not pulled up, when you pull DISC Low, it pulls up USBDP.

Thanks Todd for your time.
I agree it does seem to be doing something with the USBDM signal and I have since found out that DISC needs to be driven low in order for the USB port to work.
I probably need to find a USB specification to see why this is done.
