This register contains an 11-bit value used by the Host Controller to determine whether to
commit to the transfer of a maximum of 8-byte low-speed packet before EOF. Neither the
Host Controller nor the HCD can change this value. The bit allocation of the
HcLSThreshold register is given in

Description

Periodic Start: After a hardware reset, this field is cleared. It 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 or bulk processing. The Host
Controller, therefore, starts processing the interrupt list after completing
the current control or bulk transaction that is in progress.
