The Frame Index (FRINDEX) register is used by the Host Controller to index into the
periodic frame list. The register updates every 125 µs; once each micro frame. Bits N to 3
are used to select a particular entry in the periodic frame list during periodic schedule
execution. The number of bits used for the index depends on the size of the frame list as
set by the system software in FLS[1:0] (bits 3 to 2) of the USBCMD register. This register
must be written as a DWord. Byte writes produce undefined results. This register cannot
be written unless the Host Controller is in the halted state, as indicated by HCH (bit 12 in
the USBSTS register). A write to this register while RS (bit 0 in the USBCMD register) is
set produces undefined results. Writes to this register also affect the SOF value. The bit
allocation is given in
