This figure shows how the UTMI signals should be used in device mode.<br />

Figure 12. USBDR as Device in UTMI Mode<br />

The 1.5-K pull-up resistors that determine the speed are not externally required, and the VBUS of the<br />

<strong>MPC8313E</strong> should not be directly fed with 5-V input. The recommended voltage divider circuit is shown<br />

in Figure 12.<br />
