I'm creating a design with the LPC2148 where I don't use the USB functionality.
What should I do with the following pins:
- D+ (USB D+ Line), pin 10.
- D- (USB D- Line), pin 11.
I need to avoid EMI because my board is used in industrial applications and noisy environments.
Can I leave the pins unconnected or should I tied to ground?
What is better for EMI ?
I looked in all the available datasheets and manuals but none of them are telling what to do when not using the USB peripherals.
Thanks in advance
