Figure 7-88 shows the USB block diagram.
The accuracy of the on-chip zero-pin oscillator (Section 220.127.116.11.1, INTOSC Characteristics) will not meet the accuracy requirements of the USB protocol. An external clock source must be used for applications using USB. For applications using the USB boot mode, see Section 8.6 for clock frequency requirements.
