• Interrupt requests: Generates various interrupt signals necessary for USB
transmission/reception
• Clock: External input (48 MHz) (Refer to section 9.4.1, Frequency Control Register (FRQCR),
and section 9.4.2, USB Clock Frequency Control Register (UCLKCR))
• Power-down mode
Power consumption can be reduced by stopping UDC internal clock when USB cable is
disconnected
Automatic transition to/recovery from suspend state
• Can be connected to a Philips PDIUSBP11 Series transceiver or compatible product in internal
transceiver bypass mode (the XVEROFF bit in XVERCR is set to 1)
When using a compatible product, carry out evaluation and investigation with the
manufacturer supplying the transceiver beforehand.
• Power mode: Self-powered
