12.8.13 Note on USB Bus Disconnection
If the connector is disconnected by the user regardless of whether communication is in progress
with the host or the idle state is entered, the USB cable may be disconnected. When the USB cable
is disconnected and data transfer is performed between the USB module and the host, the correct
transfer cannot be performed after the cable is connected again. Therefore, when the cable
disconnection is detected, the USB module must be reset. To reset this, set the USBSWRST bit in
PFCR3 to 1. The CPU must access PFCR3. After the USBSWRST bit is set to 1 and one clock is
elapsed, clear the USBSWRST bit to 0. Then, the USB module operates normally. After a reset,
values of all registers in the USB module are returned to the initial values so they should be set
again.
12.8.14 Example of External Circuit
Since this LSI does not contain the on-chip USB physical layer, the physical layer LSI in the
UTMI specification should be connected externally. Figure 12.19 shows a connection example of
the external circuit. Figure 12.19 is only an example. The actual connecting differs according to
the specifications of the external physical layer LSI in the UTMI specification.
