While in Low Power Mode, the Data interface is redefined so that the Link can monitor Linestate and
the Vbus voltage. In Low Power Mode DATA[3:0] are redefined as shown in
Mapping During Low Power
receivers. The “int” or interrupt signal indicates an unmasked interrupt has occurred. When an
unmasked interrupt or linestate change has occurred, the Link is notified and can determine if it should
wake-up the PHY.
An unmasked interrupt can be caused by the following comparators changing state, VbusVld, SessVld,
SessEnd, and IdGnd. If any of these signals change state during Low Power Mode and either their
rising or falling edge interrupt is enabled, DATA[3] will assert. During Low Power Mode, the VbusVld
and SessEnd comparators can have their interrupts masked to lower the suspend current. Refer to
Section 6.1.9.4, "Minimizing Current in Low Power
While in Low Power Mode, the Data bus is driven asynchronously because all of the PHY clocks are
stopped during Low Power Mode.
