• Clock: Selection by means of EXCPG
For details, see section 11, Extend Clock Pulse Generator for USB (EXCPG).
• Power-down mode
Power consumption can be reduced by stopping internal clock when UDC cable is
disconnected
Automatic transition to/recovery from suspend state
• Can be connected to a Philips PDIUSBP11 Series transceiver or compatible product (when
using a compatible product, carry out evaluation and investigation with the manufacturer
supplying the transceiver beforehand)
