Table 107. N based value of FLS[1:0]
The Periodic Frame List Base Address (PERIODICLISTBASE) register contains the
beginning address of the periodic frame list in the system memory. If the Host Controller is
in 64-bit mode, as indicated by logic 1 in 64AC (bit 0 of the HCCPARAMS register), the
most significant 32 bits of every control data structure address comes from the
CTRLDSSEGMENT register. For details on the CTRLDSSEGMENT register, refer to
Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0 . The

Description
-
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 eight times, frames or
microframes, before moving to the next index.
