System software observes the resume event on the port, delays a port resume time (nominally 20
milliseconds), then terminates the resume sequence by clearing PORTSC[FPR] in the port. The host
controller receives the write of zero to PORTSC[FPR], terminates the resume sequence and clears
PORTSC[FPR] and PORTSC[SUSP]. Software can determine that the port is enabled (not suspended) by
sampling the PORTSC register and observing that the SUSP and FPR bits are zero. Software must ensure
that the host controller is running (that is, USBSTS[HCH] is a zero), before terminating a resume by
clearing the port's PORTSC[FPR] bit. If HCH is a one when PORTSC[FPR] is cleared, then SOFs will not
occur down the enabled port and the device will return to suspend mode in a maximum of 10 milliseconds.
Table 21-63
If USBINTR[PCE] (port change interrupt enable) is a one, the host controller also generates an interrupt
on the resume event. Software acknowledges the resume event interrupt by clearing the USBSTS[PCI].
