14. HcFmInterval Register
in a Frame, (i.e., between two consecutive SOFs), and a 15-bit value indicating the Full
Speed maximum packet size that the Host Controller may transmit or receive without
causing scheduling overrun. The Host Controller Driver may carry out minor adjustment
on the FrameInterval by writing a new value over the present one at each SOF. This
provides the programmability required for the Host Controller to synchronize with an
external clocking resource and to adjust any unfixed local clock offset.
The HcFmInterval register contains a 14-bit value which indicates the bit time interval

HCD toggles this bit each time it loads a new value to FrameInterval.
This field 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 HCD.
This field specifies the interval between two consecutive SOFs in bit
times. The nominal value is set to be 11,999. HCD should store the
current value of this field before resetting the HC. By setting the
HostControllerReset field of HcCommandStatus the HC resets this
field to its nominal value. HCD may choose to restore the stored value
upon the completion of the Reset sequence.
