HcPeriodicStart register (address: value read from func0 or func1 of address
10H
+
40H)
The HcPeriodicStart register has a 14-bit programmable value that determines when
is the earliest time the Host Controller should start processing the periodic list. The bit
allocation is given in
Table 74
.

FrameNumber
: This is incremented when HcFmRemaining is
re-loaded. It needs to be rolled over to 0H after FFFFH. When
entering the USBOPERATIONAL state, this is incremented
automatically. The content is written to HCCA after the Host
Controller has incremented FrameNumber at each frame
boundary and sent a SOF but before the Host Controller reads the
first ED in that frame. After writing to HCCA, the Host Controller
sets the SF (StartofFrame) in HcInterruptStatus.

PeriodicStart:
After a hardware reset, this field is cleared. This is
then set by the HCD during the Host Controller initialization. The
value is calculated roughly as 10% of the HcFmInterval. A typical
value is 3E67H. When HcFmRemaining reaches the value
specified, processing of the periodic lists have priority over
Control/Bulk processing. The Host Controller, therefore, starts
processing the Interrupt list after completing the current Control or
the Bulk transaction that is in progress.
