USB0_ID pin connection for USB0 in LPC4367 for non OTG application

Hello,

We are using USB Type-B connector in our design and this connector has four pins D+, D-, VBUS and Ground and doesn't support OTG mode. USB0 of LPC4367 provides USB0_ID pin for OTG mode. For non-OTG mode can this pin be left open and can the USB connector be connected directly to the four pins namely D+, D-, VBUS and ground or should the interface be moved to USB1 port of LPC4367 which doesn't have an ID pin.

Hi,

This pin should be connected for an A-device (USB0_ID LOW), B-device (USB0_ID HIGH) or OTG this pin has an internal pull-up resistor.

Have a great day,
Sol
