Figure 1-7 shows the USB 2.0 ULPI Transceiver circuitry. Note that the shield for the USB
Mini-B connector (J1) can be tied to GND by a jumper on header J36 pins 1–2 (default). The
USB shield can optionally be connected through a capacitor to GND by installing a
capacitor (body size 0402) at location C202 and jumping pins 2-3 on header J36.
