I am developing a hardware for msp430f5510 i want to implement a usb functionality according to SLAA457B.
My question is: how should I leave the Xin and Xout pins, since they will not be used. options:
1) Are Xin and Xout floating around?
2) Are Xin and Xout grounded?
3) Do Xin and Xout receive a capacitor between them? How to calculate the value of this capacitor?
