Description
FrameIntervalToggle: The HCD toggles this bit whenever it loads
a new value to FrameInterval.
FSLargestDataPacket: Specifies a value which 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 which
can be sent or received by the HC 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 default value is 11999. The HCD must save
the current value of this field before resetting the HC. Setting the
HostControllerReset field of the HcCommandStatus register will
cause the HC to reset this field to its default value. HCD may
choose to restore the saved value upon completing the reset
sequence.
