halted state as indicated by the HCH (HCHalted) bit. A write to this register while the
RS (Run/Stop) bit is set produces undefined results. Writes to this register also affect
the SOF value. The bit allocation is given in

Frame Index
: Bits in this register are used for the frame number
in the SOF packet and as the index into the Frame List. The value
in this register increments at the end of each time frame (for
example, microframe). The bits used for the frame number in the
SOF token are taken from bits 13 to 3 of this register. Bits N to 3
are used for the Frame List current index. This means that each
location of the frame list is accessed 8 times (frames or
microframes) before moving to the next index.
The following illustrates values of N based on the value of the
FLS (Frame List Size) field in the USBCMD register.
