This provides the programmability necessary for the Host Controller to synchronize with
an external clocking resource and to adjust any unknown local clock offset.

Description
FrameIntervalToggle: The HCD toggles this bit whenever it loads a
new value to FrameInterval.
FSLargestDataPacket: Specifies a value that is loaded into the
largest data packet counter at the beginning of each frame. The
counter value represents the largest amount of data in bits that can be
sent or received by the Host Controller in a single transaction at any
given time, without causing a scheduling overrun. The field value is
calculated by the HCD.
reserved
FrameInterval: Specifies the interval between two consecutive SOFs
in bit times. The nominal value is set to 11999. The HCD must store
the current value of this field before resetting the Host Controller.
Setting the HostControllerReset (HCR) field of the HcCommandStatus
register causes the Host Controller to reset this field to its nominal
value. The HCD may choose to restore the stored value on completing
the reset sequence.
