The HcFmRemaining register is a 14-bit down counter showing the bit time remaining in
the current frame.

Description
Frame Interval Toggle: The HCD toggles this bit whenever it loads a new value to Frame
Interval.
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.
-
Frame Interval: This specifies the interval between two consecutive SOFs in bit times. The
nominal value is set to 11,999. The HCD must store the current value of this field before resetting
the Host Controller to reset this field to its nominal value. The HCD can then restore the stored
value on completing the reset sequence.
